Résumé
Introducción: El tratamiento de las infecciones del tracto urinario es casi siempre empírico, lo que genera una serie de problemas en la consulta diaria. Objetivo: Caracterizar clínica y microbiológicamente las infecciones de vías urinarias bajas no complicadas en pacientes de una clínica de primer nivel. Métodos: Se realizó un estudio transversal descriptivo. La identificación de las bacterias del cultivo de orina se efectuó por métodos establecidos. La prueba de susceptibilidad a los antimicrobianos se realizó por la técnica Kirby-Bauer. Se utilizó el programa estadístico SPSS versión 26, con la prueba de ji al cuadrado y un análisis multivariado discriminante. Se calculó también razón de momios con el programa Epi-Info. Resultados: Se incluyeron 270 pacientes, con frecuencia de 39,3 por ciento de cultivos positivos, y Escherichia coli como la especie predominante. Se identificaron, además, 31,3 por ciento de bacterias Gram positivas. Se presentó significancia estadística entre la infección urinaria y factores como el sexo, y la infección del tracto urinario previa en las mujeres. Se obtuvo 100 por ciento de cepas resistentes a ampicilina. En general, se obtuvieron porcentajes de resistencia altos en los antimicrobianos probados. Conclusiones: Escherichia coli fue la especie más frecuentemente aislada, sin embargo, existe una serie de microorganismos implicados en enfermedades del tracto genital como Gardnerella vaginalis, que parecen estar involucrados en la etiología de las infecciones del tracto urinario. Se identificaron factores de riesgo como el sexo biológico y las infecciones previas en mujeres. Se obtuvieron porcentajes de resistencia altos en los antimicrobianos probados(AU)
Introduction: The management of urinary tract infections is almost always empirical, which generates a series of problems in the daily consultation. Objective: To characterize, clinically and microbiologically, uncomplicated lower urinary tract infections in patients of a primary level clinic. Methods: A descriptive and cross-sectional study was carried out. Bacterial identification in urine culture was performed by established methods. Antimicrobial susceptibility testing was performed using the Kirby-Bauer technique. The statistical software SPSS (version 26) was used, with the chi squared test and multivariate discriminant analysis. Odds ratios were also calculated with the Epi-Info program. Results: A total of 270 patients were included, with a 39.3percent frequency of positive cultures and Escherichia coli as the predominant species. In addition, 31.3percent of Gram-positive bacteria were identified. There was statistical significance between urinary tract infection and factors such as sex or previous urinary tract infection in women. One result was 100percent of ampicillin-resistant strains. In general, high percentages of resistance were obtained for the tested antimicrobials. Conclusions: Escherichia coli was the most frequently isolated species; however, there is a number of microorganisms implicated in genital tract diseases, such as Gardnerella vaginalis, which appear to be involved in the etiology of urinary tract infections. Risk factors such as biological sex and previous infections in women were identified. High percentages of resistance were obtained for the tested antimicrobials(AU)

Objetivos . Describir la actividad antimicrobiana in vitro del extracto metanólico de las hojas de Bixa orellana L. contra las bacterias anaerobias asociadas a la vaginosis bacteriana y Lactobacillus spp. Materiales y métodos . Se incluyeron en el estudio ocho cepas de referencia ATCC; Gardnerella vaginalis, Prevotella bivia, Peptococcus niger, Peptostreptococcus anaerobius, Mobiluncus curtisii, Atopobium vaginae, Veillonella parvula y Lactobacillus crispatus, y 22 aislamientos clínicos; once aislados de Gardnerella vaginalis y once aislados de Lactobacillus. La susceptibilidad antimicrobiana se determinó mediante el método de difusión en agar. La concentración mínima inhibitoria (CMI) y la concentración bactericida mínima (CBM) fueron determinadas utilizando el método de dilución en agar y un método de dilución modificado, respectivamente. Resultados . Todas las cepas de referencia ATCC tuvieron un alto nivel de susceptibilidad al extracto, con excepción de P. vibia, V. parvula y L. crispatus. Interesantemente, los aislamientos clínicos de G. vaginalis y la cepa ATCC de G. vaginalis fueron los más susceptibles al extracto dados los bajos valores de CMI (1,0 - 2,0 mg/mL) y CBM (1,0 - 4,0 mg/mL), mientras que, los aislamientos clínicos de Lactobacillus spp. y la cepa ATCC de L. crispatus fueron los menos susceptibles debido a los altos valores de CMI (32,0 mg/mL) y CBM (≥ 32,0 mg/mL). Conclusiones . Los experimentos in vitro sugieren que el extracto posee propiedades antibacterianas selectivas dada su alta actividad contra bacterias anaerobias asociadas a vaginosis bacteriana y baja actividad contra especies de Lactobacillus.
Objective. To describe the in vitro antimicrobial activity of the methanolic extract of Bixa orellana L. leaves against anaerobic bacteria associated to bacterial vaginosis and Lactobacillus spp. Materials and methods. Eight ATCC reference strains; Gardnerella vaginalis, Prevotella bivia, Peptococcus niger, Peptostreptococcus anaerobius, Mobiluncus curtisii, Atopobium vaginae, Veillonella parvula, and Lactobacillus crispatus, and twenty-two clinical isolates; eleven Gardnerella vaginalis and eleven Lactobacillus strains, were included in the study. The antimicrobial susceptibility was determined by the agar diffusion method. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were determined by using agar dilution and a modified dilution plating method, respectively. Results. All ATCC reference strains showed high levels of susceptibility to the extract, except P. vibia, V. parvula and L. crispatus. Interestingly, all G. vaginalis clinical isolates and the G. vaginalis ATTC strain were the most susceptible to the extract, given their low MIC (1.0 - 2.0 mg/mL) and MBC (1.0 - 4.0 mg/mL) values, whereas, the Lactobacillus spp. clinical isolates and the L. crispatus ATCC strain were the least susceptible bacteria given their high MIC (32.0 mg/mL) and MBC (≥ 32.0 mg/mL) values. Conclusions. In vitro experiments suggest that the extract possesses selective antimicrobial properties given its high activity against bacterial vaginosis-associated anaerobic bacteria and low activity against Lactobacillus species.

Urinary tract infections are responsible for most human infections, these are caused by bacteria, fungi, protozoa and associated microorganisms. The goal of this study was to determine the rate of vaginal infection-causing agents in routine cytological exams and also to evaluate the characteristics of positive tested Pap smears. A retrospective documental with descriptive aspect research was performed in a Clinical Pathology laboratory from Maceió-AL. The results of the Pap smears exams for Trichomonas vaginalis, Gardnerella vaginalis, Candida spp and HPV were arranged in a database as well as other data such as bacterial, protozoan, fungal and viral coinfections. The sample was composed by 18.645 women who have undergone Pap smear exams from 2013 to 2017. Of these analyzed exams, 27.4% in 2013, 10.9% in 2014, 10.6% in 2015, 15.2% in 2016 and 13.67% in 2017 were within normal range, however more than half of these exams presented some infections caused by unspecific or microbiological agents. By analyzing all the reports, 4.073 (21.84%) presented inflammations caused by some species of infectious agent with the following rate order: G. vaginalis and T. vaginalis. Furthermore, it was possible to confirm high rates of coinfection by and Candida spp. The rate of genital infections in this study highlights that there is a public health matter that must be controlled, which points a greater need for monitoring, guidance and actions towards greater awareness in order to prevent these problems.
Infecções do trato urinário são responsáveis pela maior parte das infecções humanas, sendo causadas por bactérias, fungos, protozoários, e por microrganismos associados. O objetivo deste trabalho foi determinar a frequência de agentes causadores de infecções vaginais nos exames citológicos de rotina, bem como avaliar as características dos esfregaços positivos. Foi realizada uma pesquisa do tipo documental retrospectiva de aspecto descritivo, com abordagem quantitativa, em um Laboratório de Patologia Clínica de Maceió-AL. Nesse sentido, os resultados dos exames colpocitológicos para Trichomonas vaginalis, Gardnerella vaginalis, Candida spp e HPV foram organizados em um banco de dados, contendo os resultados para estes agentes, bem como a coinfecção bacteriana, protozoária, fúngica e viral. A amostra foi composta por 18.645 mulheres que realizaram exame colpocitológico, no período de 2013 a 2017. Destes exames analisados 27,4% em 2013, 10,9% em 2014, 10,6% em 2015, 15,2% em 2016 e 13,67% em 2017, estavam dentro do limite da normalidade, porém mais que a metade desses exames analisados apresentou algumas infecções causadas por agentes inespecíficos ou microbiológicos. Do total de laudos analisados, 4.073 (21,84%), apresentaram inflamações causadas por algum tipo de agente infeccioso, com a seguinte ordem de frequência: G. vaginalis, e T. vaginalis. Além disto, foi possível confirmar a elevada frequência de coinfecção entre G. vaginalis e Candida spp. Os índices de infecções genitais nesse trabalho mostram que há um problema de saúde pública que deve ser controlado, apontando uma necessidade maior de acompanhamento, orientações e de ações para uma maior conscientização para prevenir esses problemas.

Introducción: la Chlamydia trachomatis es la principal causa de infecciones bacterianas de transmisión sexual a nivel mundial. Se estima que cada año se producen 131 millones de casos. Cursa de manera asintomática, pero la infección ascendente en mujeres puede conducir a la enfermedad inflamatoria pélvica, embarazo ectópico e infertilidad. Objetivo: determinar la prevalencia de C. trachomatis en mujeres de población abierta que acuden al Hospital General de Zona No. 29. Material y métodos: se realizó la identificación de C. trachomatis por pruebas de PCR a 200 muestras de exudado vaginal y se determinó su genotipo. Paralelamente, se realizó el diagnóstico microbiológico de rutina. Resultados: la prevalencia de C. trachomatis fue del 8.5% (17/200) con una concomitancia significativa de p = 0.006 con Gardnerella vaginalis (riesgo relativo de 2.871, IC95%: 1.574-5.236). Asimismo, se identificó C. trachomatis en cinco muestras como el único agente etiológico. Dieciséis cepas de C. trachomatis pertenecieron al genotipo F. Una cepa identificada de C. trachomatis presentó motivos genéticos similares a la variante mexicana reportada en 2019. Conclusiones: la prevalencia de C. trachomatis en la población estudiada nos indica la necesidad de implementar técnicas de diagnóstico para esta bacteria. El uso de la PCR permite realizar una determinación genotípica rápida, que explicaría el comportamiento epidemiológico de la C. trachomatis y representaría una mejora significativa de la calidad de vida de la paciente.
Background: Chlamydia trachomatis is the main cause of sexually transmitted bacterial infections worldwide. An estimated of 131 million cases occur each year. It is asymptomatic, but ascending infection in women can lead to pelvic inflammatory disease, ectopic pregnancy, and infertility. Objective: To determine the prevalence of C. trachomatis in open population women who attend the Hospital General de Zona No. 29. Material and methods: Identification of C. trachomatis was carried out by PCR testing of 200 vaginal exudate samples and its genotype was determined. In parallel, a routine microbiological diagnosis was carried out. Results: The prevalence of C. trachomatis was 8.5% (17/200) with a significant concomitance of p = 0.006 with Gardnerella vaginalis (relative risk of 2.871, 95%CI: 1.574- 5.236). Likewise, C. trachomatis was identified in 5 samples as the only etiological agent. Sixteen strains of C. trachomatis belong to genotype F. An identified strain of C. trachomatis presented genetic motifs similar to the Mexican variant repor- ted in 2019. Conclusions: The prevalence of C. trachomatis in the studied population indicates the need to implement diagnostic techniques for this bacterium. The use of PCR allows a rapid genotypic determination that would explain the epidemiological behavior of C. trachomatis and would represent a sig- nificant improvement in the quality of life of the patient.

Introduction: Infertility is an important public health problem and has many causal factors. Previous findings, based mainly on culture techniques, suggest an association between infertility and changes in the vaginal microbiome. The metagenomic approach allowed the discovery of new bacterial species, previously unidentified in the female genital tract, permitting a deeper knowledge of the role of vaginal microbiome in female reproductive health. Objective: To evaluate the association of changes in the vaginal microbiota with infertility, and its repercussions on the outcome of assisted reproduction techniques after a decade of the Human Microbiome Project. Methods: A systematic search was carried out in the MEDLINE database between September and November 2018, by selecting 14 studies, associating vaginal microbiome with infertility, or with results of assisted reproduction techniques. Results: The findings showed a higher prevalence of bacterial vaginosis, and increased microbial diversity in the vagina of infertile women. Regarding the success of assisted reproduction techniques, most studies did not show any significant association between bacterial vaginosis and reduction in pregnancy rates. Conclusion: Further studies are needed to better understand the influence of the balance of vaginal microorganism species on female reproductive health, addressing the microbiome composition in contexts beyond in vitro fertilization techniques.
Introdução: A infertilidade é um importante problema de saúde pública e possui muitos fatores causais. Achados prévios, baseados principalmente em técnicas de cultura, sugerem uma associação entre infertilidade e alterações do microbioma vaginal. A abordagem metagenômica permitiu a descoberta de novas espécies bacterianas, anteriormente não identificadas, no trato genital feminino, possibilitando um conhecimento mais aprofundado do papel do microbioma vaginal na saúde reprodutiva feminina. Objetivo: Avaliar a associação das alterações da microbiota vaginal com a infertilidade e suas repercussões no resultado das técnicas de reprodução assistida após uma década do Projeto Microbioma Humano. Métodos: Foi realizada uma busca sistemática na base de dados MEDLINE, entre setembro e novembro de 2018, e selecionados 14 estudos que associavam o microbioma vaginal com a infertilidade ou com resultados de técnicas de reprodução assistida. Resultados: Os achados evidenciaram uma maior prevalência de vaginose bacteriana e um aumento da diversidade microbiana na vagina de mulheres inférteis. Com relação ao sucesso das técnicas de reprodução assistida, a maioria dos estudos não evidenciou uma associação significante entre a vaginose bacteriana e a redução nas taxas de gravidez. Conclusão: São necessários novos estudos para melhor compreender a influência do equilíbrio das espécies de microrganismos vaginais na saúde reprodutiva feminina, abordando a composição do microbioma em contextos além das técnicas de fertilização in vitro.

Vários são os fatores envolvidos na etiologia desse câncer e suas lesões precursoras. Objetivo: Verificar os principais cofatores associados às alterações cervicouterinas. Casuística e Métodos: Trata-se de um estudo analítico e documental, realizado em um laboratório do município de Surubim-PE, incluindo resultados de exames citopatológicos do período de janeiro de 2014 a dezembro de 2015. Os dados foram avaliados pelo programa PRISM versão 7.0, por meio do teste Qui-quadrado, com intervalo de confiança 95% e razão de prevalência (RP). Resultados: Foram incluídos 1.200 resultados de exames de mulheres na faixa etária entre 14 e 78 anos. Quarenta e três por cento das mulheres pertenciam à faixa etária entre 31 e 47 anos e 86,6% haviam realizado seu último exame citopatológico a menos de três anos. A faixa etária entre 14 e 30 anos esteve associada a um maior risco para o desenvolvimento das anormalidades cervicais (p< 0,001 e OR 2,9). Mulheres que realizaram o exame citopatológico a menos de três anos apresentaram uma maior associação com a presença de lesões intraepiteliais escamosas de baixo grau (LSIL) e atipias escamosas (p < 0,0001 e OR 11,3). A lesão intraepitelial escamosa de baixo grau foi a anormalidade cervical de maior frequência, correspondendo a 46,3%. Mulheres com presença de Gardnerella vaginalis e/ou Mobiluncus spp. apresentaram associação com a presença de anormalidades cervicais (p< 0,0001). Conclusão: Mulheres abaixo de 30 anos, que realizaram exame citopatológico a menos de três anos ou apresentam Gardnerella vaginalis e/ou Mobiluncus spp.devem ser acompanhadas quanto aos possíveis riscos associados ao desenvolvimentode alterações cervicouterinas.
Introduction: Cervical cancer is still a serious public health problem in our country. It appears third among the most common types of cancer among women. Several are the factors involved in the etiology of this cancer and its precursor lesions. Objective: Verify the main cofactors associated with the changes in the cervix of the uterus. Patients and Methods:This is an analytical and documentary study, carried out in a laboratory in the municipality of Surubim-PE, including results of cytopathological exams from January 2014 to December 2015. Data were evaluated using the software PRISM version 7.0, by the Chi-square test, with 95% confidence interval and prevalence ratio (PR). Results: We included 1,200 tests results of women in the age between 14 and 78 years. Forty-three percent of the women were in the age group from 31 to 47 years and 86.6% had performed their last cytopathological examination less than three years. The age group ranging from 14 to 30 years was associated with a higher risk for the development of cervical abnormalities (p< 0.001 and OR 2.9). Women who underwent cytopathological examination less than three years presented a greater association with the presence of low squamous intraepithelial lesions (LSIL) and squamous atypia (p< 0.0001 and OR 11.3). The low-grade squamous intraepithelial lesion was the most frequent cervical abnormality, corresponding to 46.3%. Conclusion: Women under 30 years, who performed cytopathological examination at less than three years or present Gardnerella vaginalis and / or Mobiluncus spp. should be accompanied for the possible risks associated with the development of the changes in the cervix of uterus.

Background: Gardnerella vaginalis is a bacterial vaginosis (BV)-associated vaginal bacterium that produces the toxin vaginolysin (VLY). VLY is a pore-forming toxin that is suggested to be the main virulence factor of G. vaginalis. The high recurrence rate of BV and the emergence of antibiotic-resistant bacterial species demonstrate the need for the development of recombinant antibodies as novel therapeutic agents for disease treatment. Single-chain variable fragments (scFvs) generated against VLY exhibited reduced efficacy to neutralize VLY activity compared to the respective full-length antibodies. To improve the properties of scFvs, monospecific dimeric scFvs were generated by the genetic fusion of two anti-VLY scFv molecules connected by an alpha-helix-forming peptide linker. Results: N-terminal hexahistidine-tagged dimeric scFvs were constructed and produced in Escherichia coli and purified using metal chelate affinity chromatography. Inhibition of VLY-mediated human erythrocyte lysis by dimeric and monomeric scFvs was detected by in vitro hemolytic assay. The circulating half-life of purified scFvs in the blood plasma of mice was determined by ELISA. Dimeric anti-VLY scFvs showed higher neutralizing potency and extended circulating half-life than parental monomeric scFv. Conclusions: The protein obtained by the genetic fusion of two anti-VLY scFvs into a dimeric molecule exhibited improved properties in comparison with monomeric scFv. This new recombinant antibody might implement new possibilities for the prophylaxis and treatment of the diseases caused by the bacteria G. vaginalis.

BACKGROUND: Bacterial vaginosis (BV) is the most prevalent cause of symptomatic vaginitis. In the Philippines, prevalence of BV is at 28.16%. The mainstay for the treatment of BV is Metronidazole. Although antibiotic therapy has been shown to eliminate BV associated organisms, there is extremely high recurrence rate.OBJECTIVE: To compare the efficacy of metronidazole and metronidazole plus lactobacilli tablet in the treatment of bacterial vaginosis among non-pregnant patients seen at the outpatient department of a tertiary medical center.METHODOLOGY: The population included non-pregnant women ages 15 t0 44 years old, with bacterial vaginosis diagnosed by Amsel's criteria and Nugent's scoring. The participants were randomly assigned to their treatment group, one is Metronidazole only and other received Metronidazole plus Lactobacillus tablet. All participants followed up on day 8,15,22 and 56 from initiation of treatment resolution or persistence of symptoms and collection of vaginal specimen for gram stain and inquire on adverse effects.RESULTS: On day 8 treatment, there were significantly more participant in the metronidazole plus probiotic arm with an estimated lactobacilli count of more than 30/hpf as comapred to metronidazole alone. On day 15 post treatment, there was no statistically significant difference with the estimated Gardnerella vaginalis count, lactobacilli count, presence or absence of malodorous vaginal discharge between the metronidazole plus probiotic and the metronidazole alone arm. With metronidazole plus probiotic group, the proportion of women with less than 30 per hpf Gardnella vaginalis count and absent foul smelling vaginal discharge were accounted among 100% of the participants from day 8 to 56 post treatment. The early reduction in the causative agent and symptoms can be attributed to an increase in the estimated lactobacilli count sustained until 56 days post treatment metronidazole plus probiotic. However, from day 15 to 22 and 56 post- treatment, the proportion of participants who had a nugent's score of less than 4 were greater for both the metronidazole plus probiotic (100%) and metronidazole alone (95%) arm, when compared to day 8 post-treatment. This finding for the metronidazole plus probiotic group is due to sustained reduction in the Gardnella vaginalis count and increase in lactobacilli counts. Potentially , the metronidazole plus probiotic treatment was found to be more favorable in sustaining the normal flora and probiotic can be used as an adjunct may enhance the efficacy of metronidazole in the treatment of BV.CONCLUSION: Metronidazole plus probiotic and metronidazole only treatment are comparable in treating bacterial vaginosis. In terms of restoring and maintaining the normal flora, metronidazole plus probiotic appears to be more significantly efficacious. Probiotic in the form of lactobacilli is a promising adjunct to enhance the efficacy of metronidazole in the treatment of bacterial vaginosis.

Although antibiotic therapy has been shown to eliminate BV associated organisms, there is extremely high recurrence rate.OBJECTIVE: To compare the efficacy of metronidazole and metronidazole plus lactobacilli tablet in the treatment of bacterial vaginosis among non-pregnant patients seen at the outpatient department of a tertiary medical center.METHODOLOGY: The population included non-pregnant women ages 15 t0 44 years old, with bacterial vaginosis diagnosed by Amsel's criteria and Nugent's scoring. The participants were randomly assigned to their treatment group, one is Metronidazole only and other received Metronidazole plus Lactobacillus tablet. All participants followed up on day 8,15,22 and 56 from initiation of treatment resolution or persistence of symptoms and collection of vaginal specimen for gram stain and inquire on adverse effects.RESULTS: On day 8 treatment, there were significantly more participant in the metronidazole plus probiotic arm with an estimated lactobacilli count of more than 30/hpf as comapred to metronidazole alone. On day 15 post treatment, there was no statistically significant difference with the estimated Gardnerella vaginalis count, lactobacilli count, presence or absence of malodorous vaginal discharge between the metronidazole plus probiotic and the metronidazole alone arm. With metronidazole plus probiotic group, the proportion of women with less than 30 per hpf Gardnella vaginalis count and absent foul smelling vaginal discharge were accounted among 100% of the participants from day 8 to 56 post treatment. The early reduction in the causative agent and symptoms can be attributed to an increase in the estimated lactobacilli count sustained until 56 days post treatment metronidazole plus probiotic. However, from day 15 to 22 and 56 post- treatment, the proportion of participants who had a nugent's score of less than 4 were greater for both the metronidazole plus probiotic (100%) and metronidazole alone (95%) arm, when compared to day 8 post-treatment. This finding for the metronidazole plus probiotic group is due to sustained reduction in the Gardnella vaginalis count and increase in lactobacilli counts. Potentially , the metronidazole plus probiotic treatment was found to be more favorable in sustaining the normal flora and probiotic can be used as an adjunct may enhance the efficacy of metronidazole in the treatment of BV.CONCLUSION: Metronidazole plus probiotic and metronidazole only treatment are comparable in treating bacterial vaginosis. In terms of restoring and maintaining the normal flora, metronidazole plus probiotic appears to be more significantly efficacious. Probiotic in the form of lactobacilli is a promising adjunct to enhance the efficacy of metronidazole in the treatment of bacterial vaginosis.

BACKGROUND: Next-generation sequencing (NGS) can detect many more microorganisms of a microbiome than traditional methods. This study aimed to analyze the vaginal microbiomes of Korean women by using NGS that included bacteria and other microorganisms. The NGS results were compared with the results of other assays, and NGS was evaluated for its feasibility for predicting vaginitis. METHODS: In total, 89 vaginal swab specimens were collected. Microscopic examinations of Gram staining and microbiological cultures were conducted on 67 specimens. NGS was performed with GS junior system on all of the vaginal specimens for the 16S rRNA, internal transcribed spacer (ITS), and Tvk genes to detect bacteria, fungi, and Trichomonas vaginalis. In addition, DNA probe assays of the Candida spp., Gardnerella vaginalis, and Trichomonas vaginalis were performed. Various predictors of diversity that were obtained from the NGS data were analyzed to predict vaginitis. RESULTS: ITS sequences were obtained in most of the specimens (56.2%). The compositions of the intermediate and vaginitis Nugent score groups were similar to each other but differed from the composition of the normal score group. The fraction of the Lactobacillus spp. showed the highest area under the curve value (0.8559) in ROC curve analysis. The NGS and DNA probe assay results showed good agreement (range, 86.2-89.7%). CONCLUSIONS: Fungi as well as bacteria should be considered for the investigation of vaginal microbiome. The intermediate and vaginitis Nugent score groups were indistinguishable in NGS. NGS is a promising diagnostic tool of the vaginal microbiome and vaginitis, although some problems need to be resolved.

Bacterial vaginosis (BV) is the most frequent vaginal disease being apt to relapse. The growth inhibition effect of the mixture of citric acid (CA) and trisodium phosphate (TSP) on BV causative bacteria and probiotics was measured. Gardnerella vaginalis was reduced to zero in WCCT-1 (CA 0.25% and TSP 0.55% in Wilkins-Chalgren broth), 2.0 x 10(4)/ml in WCCT-2 (CA 0.5% and TSP 0.8% in WC), and 3.3 x 10(3)/ml in WCCT-3 (CA 1.0% and TSP 2.6% in WC) comparing with 1.3 x 10(5)/ml in WC after 48 h. Bacteroides fragilis was reduced to 6.0 x 10(3)/ml in WCCA (CA 0.34% in WC), 2.3 x 10(2)/ml in WCCT (CA 0.5% and TSP 0.2% in WC), 7.0 x 10(3)/ml in WCHCl (HCl in WC) after 48 h. Mobiluncus mulieris was reduced to 1.08 x 10(4)/ml in WCCA, 1.03 x 10(3)/ml in WCCT, and 10 ea/ml in WCHCl after 48 h. Peptostreptococcus asaccharolyticus was completely inhibited in WCCA, WCCT, and WCHCl after 24 h. Probiotics, Steroidobacter denitrificans YH1 (3.4 x 10(7)/ml) and Lactobacillus crispatus YH2 (2.7 x 10(6)/ml), grew to 1.25 x 10(8)/ml and 2.6 x 10(7)/ml in MRSCA (CA 1.0% in MRS), 1.8 x 10(7)/ml and 4.6 x 10(6)/ml in MRSCT (CA 1.5% and TSP 0.58% in MRS), 1.2 x 10(8)/ml and 2.3 x 10(7)/ml in MRSHCl after 48 h, respectively. These results mean that the CA-TSP mixture can be used as the useful vaginal pH controller, growth inhibitor on BV causative bacteria, and an efficient means for settlement of probiotics.

BACKGROUND: Infectious vaginitis is a common gynecologic disease that is primarily caused by three pathogens (Trichomonas vaginalis, Gardnerella vaginalis, and Candida species). The aim of this study was to confirm the effects of other infectious vaginitis-related test results on the interpretation of Gram stain and Papanicolaou (Pap) smear test results for disease diagnosis. METHODS: A total of 300 vaginal samples were collected from women presenting symptoms of vaginitis. The presence of the three previously mentioned pathogens was evaluated using both a Gram stain and Pap smear test, and interpreted twice by 4 different observers. The first interpretation was performed without any information, and a second interpretation was performed with knowledge of results of an Affirm VPIII test that was used to diagnose infectious vaginitis. The results from the two interpretations were compared and the sensitivity and specificity of both tests were evaluated. RESULTS: For the Gram stain samples, the detection rates of G. vaginalis were increased in the second interpretation by 6.2%, while the detection rates of Candida spp. were decreased by 0.3%. For the Pap smear test samples, the detection rates of G. vaginalis were increased in the second interpretation by 7.0%, and the detection rates of Candida spp. were increased by 2.0%. The sensitivity of both tests was increased in the second interpretation by 5.5% to 66.7%. There was no difference in the specificity between the two interpretations. CONCLUSIONS: We demonstrated that there is significant inter-observer variation when using Gram stain and Pap smear test results to diagnose infectious vaginitis. The detection rates and sensitivity of both tests changed when the results from an additional test were incorporated into the interpretation. Additional studies are needed to develop objective criteria and a standardized interpretation system for the evaluation of results from these diagnostic tests.

Two Gram-positive rod strains isolated from the healthy vagina of a woman were tested for the possibility as probiotics. One strain was identified as Steroidobacter denitrificans (YH1) and the other as Lactobacillus crispatus (YH2) by 16S rRNA partial sequencing. The Casman agar and Man-Rogosa-Sharpe (MRS) agar were mixed in same quantity, supplemented with 5% human rbc lysate (CMB agar). The Wilkins-Chalgren agar and MRS agar were mixed in same quantity (WCM agar). Gardnerella vaginalis was cultured in Casman broth, supplemented with 5% human rbc lysate and 1,000 x-diluted with normal saline. Bacteroides fragilis, Mobiluncus mulieris and Peptostreptococcus asaccharolyticus were cultured in Wilkins-Chalgren anaerobe broth and 2,000x-diluted. S. denitrificans YH1 and L. crispatus YH2 were cultured in MRS broth anaerobically and 100x-diluted. The diluted suspensions of B. fragilis, M. mulieris and P. asaccharolyticus were inoculated on WCM agar and G. vaginalis on CMB agar by cotton swabs. Ten microl aliquots of YH1 and YH2 were inoculated on the center of WCM agar and CMB agar. The growth inhibition zone diameters of B. fragilis, G. vaginalis, M. mulieris and P. asaccharolyticus by YH1 were 35 mm, 35 mm, 25 mm and 60 mm. The inhibition diameters by YH2 were 25 mm, 30 mm, 20 mm and 40 mm, respectively. These results implicate that S. denitrificans YH1 can be the stronger probiotics for the treatment of bacterial vaginosis than L. crispatus, compared inhibition zone diameters by YH1 and YH2.

ABSTRACT BACKGROUND: Bacterial vaginosis (BV) is the most common cause of vaginal discharge in women of reproductive age. The purpose of this study was to determine the frequency of BV in Bulgarian pregnant and nonpregnant women from several age ranges and to compare three different laboratory methods for Gardnerella vaginalis detection in patents suffering from BV. METHODS: Between September 2011 and June 2012, 809 women of 16-40 years of age separated in two major groups: nonpregnant - 469 (355 with and 114 without symptoms) and pregnant - 340 (213 and 127 respectively) were enrolled for the study. The women underwent three different laboratory tests simultaneously: scoring of Gram staining of vaginal smear, culture, and polymerase chain reaction (PCR) assay for G. vaginalis. RESULTS: The microscopic method detected high frequency of BV in symptomatic (57%) whereas only a minority of asymptomatic subjects (14%) were detected. G. vaginalisassociated BV was diagnosed in approximately equal proportions when evaluated with PCR and microscopic method for both pregnant and nonpregnant women. The comparative analysis of microscopic evaluation, culture and PCR assays demonstrated greater concurrence (about 90%) between Gram staining and PCR detection for BV, than both methods compared to culture. The combination of microscopy and PCR turned out to be very reliable and repeatable for detecting G. vaginalis-associated BV. CONCLUSIONS: This is the first comparative investigation on the epidemiology of G. vaginalisassociated BV in Bulgaria. The established highest frequency in the young Bulgarian women (21-30 years) is alarming and should be considered in prophylaxis and reproductive programmes.

BACKGROUND: The standard treatment for bacterial vaginosis is metronidazole. Side effects are not well tolerated by some patients and some develop resistance. Hence, the search for treatment with less side effects and less resistance. OBJECTIVES: To determine the efficacy of vaginal dequalinium chloride compared to oral metronidazole in the treatment of bacterial vaginosis among non; pregnant women. METHOD: Fourty non-pregnant women and non lactating women, 18-50 years old diagnosed with bacterial vaginosis by presence of vaginal discharge and malodor, Nugent's score of 4 and above, and clue cells seen in Gram stain, were randomly allocated to treatment groups. Group A received dequalinium chloride 10mg/vaginal tablet for 6 days at HS while Group B received metronidazole tablet, 500mg/tablet, 1 tablet per orem BID for 7 days. Microbiologic, clinical and complete cure rate as well as adverse effects of treatment were then assessed. Data entry and encoding was done using Epi info version 6. Analysis was done using stata version 9. Univariate analysis such as mean, median, mode and range were used to describe the characteristics of the subjects. Frequency distribution was used to describe the proportion of patients with microbiologic, clinical and complete cure. This was also used in describing proportion of the participants' acceptability in this study. Chi square was used for comparison of dequalinium chloride and metronidazole between treatment-arms. RESULTS: Ninety five percent (19/20) of those in the dequalinium arm had gram-negative coccobacilli count of less than 10/hpf as compared to 80% (16/20) among those in the control (P < 0.30). Lactobacilli was only restored among 25% of those in the metronidazole and in 75% of the control group (P = 0.002). Reduced amount of discharge was observed in all paricipants in both groups. Malodor of the discharge disappeared in 95% (19/20) of the H2O2 and 85% (17/20) of the control group (P=0.30). CONCLUSION: Dequalinium is comparable with the standard treatment. It is at par with the standard treatment in alleviating symptoms of bacterial vaginosis and reducing estimated coccobacilli. It is more effacious in restoring the normal flora.

A vagina possui um variado número de bactérias que vivem em harmonia com os Lactobacillus spp. Quando ocorre um desequilíbrio na flora, há um crescimento exagerado de bactérias em especial Gardnerella vaginalis, causando a vaginose bacteriana. Este trabalho tem por objetivo verificar a incidência de G. vaginalis nas amostras de secreção vaginal em mulheres atendidas pelo Laboratório Municipal de Fraiburgo. O estudo foi realizado no referido laboratório. Os dados foram coletados através dos laudos dos exames de secreção vaginal. Foram avaliados os dados referentes aos exames realizados em mulheres da faixa etária de 18 a 55 anos no período de 1 ano, totalizando 451 exames realizados neste período. Os resultados mostram que 54 exames foram positivos para G. vaginalis, 32 casos de Candida spp., 13 casos de Trichomonas spp. e 352 exames apresentaram-se normais. Em outras palavras 78% dos exames realizados apresentam-se normais e 22% dos exames apresentam resultado positivo para vulvovaginites. Foi observado ainda que a maior incidência de Gardnerella spp. esteja associada à faixa etária de 20 a 30 anos, demonstrando assim que esta infecção acomete principalmente mulheres em idade reprodutiva. Como sendo um dos principais agentes causadores de infecções em mulheres e pela carência de estudos epidemiológicos sobre estes agentes, é de fundamental importância um estudo nessa área, este será de grande valia não só para as usuárias do SUS, como para a equipe de saúde, como ação educativa para prevenção, controle e a solução para este problema que é a principal queixa entre as mulheres
The vagina has a number of different bacteria that live in harmony with Lactobacillus spp. When an imbalance occurs in this flora, there is an overgrowth of bacteria, in particular Gardnerella vaginalis, causing bacterial vaginosis. The aim of this study was to determine the incidence of Gardnerella vaginalis in samples of vaginal secretion in women attending the Municipal Laboratory at Fraiburgo. The study was conducted in that laboratory. Data were collected through the reports of examinations of vaginal discharge. These examinations were performed on women aged 18 to 55 years over a period of one year, totaling 451 tests overall. The results show that 54 cases were positive for Gardenerella vaginalis, 32 for Candida spp., 13 for Trichomonas spp. and 352 examinations were normal; hence, 78% of the exams were normal and 22% positive for vulvovaginitis. It was also observed that the highest incidence of Gardnerella spp was associated with an age range from 20 to 30 years, showing that this infection primarily affects women of reproductive age. As this is one of the main causative agents of infections in women and given the lack of epidemiological studies on these bacteria, a study of this type is vitally important and will be of great value not only for the users of the public health system and for the health team, but also as an educational activity for the prevention, control and solution of this problem, which is the main complaint among women.
