The bacterial microbiota of Hunner lesion interstitial cystitis/bladder pain syndrome.

OBJECTIVE: To undertake the first comprehensive evaluation of the urinary microbiota associated with Hunner lesion (HL) interstitial cystitis/bladder pain syndrome (IC/BPS). Despite no previous identification of a distinct IC/BPS microbial urotype, HL IC/BPS, an inflammatory subtype of IC/BPS, was hypothesized most likely to be associated with a specific bacterial species or microbial pattern. PARTICIPANTS AND METHODS: The bacterial microbiota of midstream urine specimens from HL IC/BPS and age- and gender-matched IC/BPS patients without HL (non-HL IC/BPS) were examined using the pan-bacterial domain clinical-level molecular diagnostic Pacific Biosciences full-length 16S gene sequencing protocol, informatics pipeline and database. We characterized the differential presence, abundances, and diversity of species, as well as gender-specific differences between and among HL and non-HL IC/BPS patients. RESULTS: A total of 59 patients with IC/BPS were enrolled (29 HL, 30 non-HL; 43 women, 16 men) from a single centre and the microbiota in midstream urine specimens was available for comparison. The species abundance differentiation between the HL and non-HL groups (12 species) was not significantly different after Bonferroni adjustments for multiple comparisons. Similarly, the nine differentiating species noted between female HL and non-HL patients were not significantly different after similar statistical correction. However, four species abundances (out of the 10 species differences identified prior to correction) remained significantly different between male HL and non-HL subjects: Negativicoccus succinivorans, Porphyromonas somerae, Mobiluncus curtisii and Corynebacterium renale. Shannon diversity metrics showed significantly higher diversity among HL male patients than HL female patients (P = 0.045), but no significant diversity differences between HL and non-HL patients overall. CONCLUSIONS: We were not able to identify a unique pathogenic urinary microbiota that differentiates all HL from all non-HL IC/BPS. It is likely that the male-specific differences resulted from colonization/contamination remote from the bladder. We were not able to show that bacteria play an important role in patients with HL IC/BPS.

Low prevalence of Cutibacterium acnes in prostatic tissue biopsies in a French hospital.

We evaluated the Cutibacterium acnes prevalence in prostatic biopsies and characterized the strains at a molecular level. 18 out of 36 biopsies (50%) were sterile after seven days in culture. C. acnes was observed in only two biopsies. Its prevalence was low (5.6%). Finally, the molecular characterization revealed diverse clusters including phylotypes IA1, IB and II.

Cervicovaginal microbiota and local immune response modulate the risk of spontaneous preterm delivery.

Failure to predict and understand the causes of preterm birth, the leading cause of neonatal morbidity and mortality, have limited effective interventions and therapeutics. From a cohort of 2000 pregnant women, we performed a nested case control study on 107 well-phenotyped cases of spontaneous preterm birth (sPTB) and 432 women delivering at term. Using innovative Bayesian modeling of cervicovaginal microbiota, seven bacterial taxa were significantly associated with increased risk of sPTB, with a stronger effect in African American women. However, higher vaginal levels of ß-defensin-2 lowered the risk of sPTB associated with cervicovaginal microbiota in an ethnicity-dependent manner. Surprisingly, even in Lactobacillus spp. dominated cervicovaginal microbiota, low ß-defensin-2 was associated with increased risk of sPTB. These findings hold promise for diagnostics to accurately identify women at risk for sPTB early in pregnancy. Therapeutic strategies could include immune modulators and microbiome-based therapeutics to reduce this significant health burden.

Changes in the Vaginal Microenvironment as Related to Frequency of Pessary Removal.

OBJECTIVE: The aim of the study was to describe the effect of frequency of pessary removal on the vaginal microenvironment. METHODS: We performed a secondary analysis of a multicenter randomized trial of hydroxyquinoline gel in women presenting for pessary fitting. Patients had vaginal secretions analyzed at baseline, 2 weeks, and 3 months. Patients were stratified by frequency of pessary removal at least once daily, at least once weekly, and less often than once weekly. These groups were compared for prevalence of Lactobacillus predominance (primary outcome), anaerobic predominance, Mobiluncus prominence, vaginal symptoms, and bacterial vaginosis by Nugent criteria, and correction for confounding variables was performed. RESULTS: One hundred thirty-seven women were included in this analysis: 34 (25%) removed the pessary daily, 54 (39%) at least weekly, and 49 (36%) less often than once weekly. Women who removed the pessary less often than weekly were older (P < 0.01), using more hormone therapy (P = 0.03), and more likely to have bacterial vaginosis at baseline (P < 0.01). At 2 weeks, the predominance of Lactobacillus in the group removing pessary daily was higher (41% daily vs 24% weekly vs 9% longer, P = 0.03) and this persisted after confounder correction (P < 0.01). Women who removed their pessary less than weekly were more likely to have anaerobic predominance at 3 months (P = 0.04). CONCLUSIONS: Women who remove their pessaries less often than once weekly have an increased prevalence of anaerobes at 3 months, but no difference in vaginal symptoms or pessary satisfaction.

Establishment of a sensitive system for analysis of human vaginal microbiota on the basis of rRNA-targeted reverse transcription-quantitative PCR.

Ten specific primer sets, for Lactobacillus gasseri, Lactobacillus crispatus, Atopobium vaginae, Gardnerella vaginalis, Mobiluncus curtisii, Chlamydia trachomatis/muridarum, Bifidobacterium longum subsp. longum, Bifidobacterium longum subsp. infantis, Bifidobacterium adolescentis, and Bifidobacterium angulatum, were developed for quantitative analysis of vaginal microbiota. rRNA-targeted reverse transcription-quantitative PCR (RT-qPCR) analysis of the vaginal samples from 12 healthy Japanese volunteers using the new primer sets together with 25 existing primer sets revealed the diversity of their vaginal microbiota: Lactobacilli such as L. crispatus, L. gasseri, Lactobacillus jensenii, Lactobacillus iners, and Lactobacillus vaginalis, as the major populations at 10(7) cells/ml vaginal fluid, were followed by facultative anaerobes such as Streptococcus and strict anaerobes at lower population levels of 10(4) cells/ml or less. Certain bacterial vaginosis (BV)-related bacteria, such as G. vaginalis, A. vaginae, M. curtisii, and Prevotella, were also detected in some subjects. Especially in one subject, both G. vaginalis and A. vaginae were detected at high population levels of 10(8.8) and 10(8.9) cells/ml vaginal fluid, suggesting that she is an asymptomatic BV patient. These results suggest that the RT-qPCR system is effective for accurate analysis of major vaginal commensals and diagnosis of several vaginal infections.

Association between BVAB1 and high Nugent scores among women with bacterial vaginosis.

As part of a larger study using 454 pyrosequencing to investigate the vaginal microbiota of women with bacterial vaginosis (BV), we found an association between a novel BV-associated bacterium (BVAB1) and high Nugent scores and propose that BVAB1 is the curved Gram-negative rod traditionally identified as Mobiluncus spp. in vaginal Gram stains.

Early pregnancy changes in bacterial vaginosis-associated bacteria and preterm delivery.

BACKGROUND: We evaluated the importance of measuring early vaginal levels of eight bacterial vaginosis (BV)-associated bacteria, at two points in pregnancy, and the risk of spontaneous preterm delivery (SPTD) among pregnant women and the subgroup of pregnant women with a history of preterm delivery (PTD). METHODS: This prospective cohort study enrolled women at five urban obstetric practices at Temple University Hospital in Philadelphia PA. Women with singleton pregnancies less than 16 weeks gestation self-collected vaginal swabs at two points in pregnancy, prior to 16 weeks gestation and between 20-24 weeks gestation, to measure the presence and level of eight BV-associated bacteria. Women were followed-up for gestational age at delivery via medical records. RESULTS: Among women reporting a prior PTD, women with higher levels of Leptotrichia/Sneathia species, BVAB1 and Mobiluncus spp., prior to 16 weeks gestation, were significantly more likely to experience a SPTD. In addition, pregnant women with a prior PTD and increasing levels of Leptotrichia/Sneathia species (aOR: 9.1, 95% CI 1.9, 42.9), BVAB1 (aOR: 16.4, 95% CI 4.3, 62.7) or Megasphaera phylotype 1 (aOR: 6.2, 95% CI 1.9, 20.6), through 24 weeks gestation, were significantly more likely to experience an SPTD. Among the overall group of pregnant women, the levels of BV-associated bacteria were not related to SPTD. CONCLUSION: Among the group of women reporting a prior PTD, increasing levels of BVAB1, Leptotrichia/Sneathia species, and Megasphaera phylotype 1, through mid-pregnancy were related to an increased risk of SPTD.

Mycoplasma, bacterial vaginosis-associated bacteria BVAB3, race, and risk of preterm birth in a high-risk cohort.

OBJECTIVE: Genital tract infection accounts for approximately 25-40% of all preterm births. We sought to assess the relationship between preterm birth and selected vaginal bacterial taxa associated with preterm birth either directly or through their association with bacterial vaginosis (BV). STUDY DESIGN: Vaginal fluid for Gram stain was collected between 17 and 22 weeks' gestation as part of a randomized trial of ultrasound-indicated cerclage for preterm birth prevention in women at high risk for recurrent spontaneous preterm birth. Bacterial deoxyribonucleic acid was extracted from the Gram stain slides and analyzed using quantitative polymerase chain reaction. RESULTS: Among the 499 participants, Mycoplasma was positively correlated with increased risk of preterm (risk ratio [RR], 1.83; 95% confidence interval [CI], 1.52-2.22) as was Mobiluncus (RR, 1.36; 95% CI, 1.07-1.73) and Atopobium (RR, 1.44; 95% CI, 1.1-1.87). However, there were strong interactions between the race/ethnic group and the presence of these and other individual taxa on risk of preterm birth. By contrast, bacterial vaginosis-associated bacteria (BVAB)-3 was consistently associated with a reduction in the risk of preterm birth for all racial/ethnic groups (0.55; 95% CI, 0.39-0.78). CONCLUSION: BV is characterized by a reduction of Lactobacillus, and lactic acid-producing bacteria and the presence of Mobiluncus; we found these factors and the presence of Mycoplasma to be associated with an increased risk of preterm birth. By contrast, the presence of a recently identified organism sufficient to cause BV, BVAB3, decreased the risk of preterm birth. These findings give insight into why treating BV has mixed impact on risk of preterm birth.

Fast and effective paper based sensor for self-diagnosis of bacterial vaginosis.

In this contribution we present a sensitive colorimetric bioactive paper fabricated to determine sialidase-related diseases like bacterial vaginosis (BV) in a one-step and dry format spot assay with fast response and good storage stability. The paper was prepared by three simple steps. The first step involves preparation of poly(ethyleneimine) (PEI) microcapsules, the second step is to incubate positively charged microcapsules in negatively charged 5-bromo-4-chloro-3-indolyl-a-D-N-acetylneuraminic acid (BCIN) solution, a color enhancer nitro blue tetrazolium (NBT), and in the third step, paper was fabricated by incorporating incubated microcapsules into paper pulp. This paper changes color from white to dark purple in the presence of sialidase in as little as 6min, and color could be enhanced with increased length of reaction time. In this reaction system, BCIN was the substrate for sialidase, NBT was the color enhancer, and PEI microcapsules acted as catalyst. The loading efficiency of BCIN was about 22.2%, and filtered BCIN solution could be reused for the next fabrication.

A multi-omic systems-based approach reveals metabolic markers of bacterial vaginosis and insight into the disease.

BACKGROUND: Bacterial vaginosis (BV) is the most common vaginal disorder of reproductive-age women. Yet the cause of BV has not been established. To uncover key determinants of BV, we employed a multi-omic, systems-biology approach, including both deep 16S rRNA gene-based sequencing and metabolomics of lavage samples from 36 women. These women varied demographically, behaviorally, and in terms of health status and symptoms. PRINCIPAL FINDINGS: 16S rRNA gene-based community composition profiles reflected Nugent scores, but not Amsel criteria. In contrast, metabolomic profiles were markedly more concordant with Amsel criteria. Metabolomic profiles revealed two distinct symptomatic BV types (SBVI and SBVII) with similar characteristics that indicated disruption of epithelial integrity, but each type was correlated to the presence of different microbial taxa and metabolites, as well as to different host behaviors. The characteristic odor associated with BV was linked to increases in putrescine and cadaverine, which were both linked to Dialister spp. Additional correlations were seen with the presence of discharge, 2-methyl-2-hydroxybutanoic acid, and Mobiluncus spp., and with pain, diethylene glycol and Gardnerella spp. CONCLUSIONS: The results not only provide useful diagnostic biomarkers, but also may ultimately provide much needed insight into the determinants of BV.

[Microscopic examination of vaginal discharge specimens for Trichomonas vaginalis and other micro-organisms in 18-45 age group women]. / 18-45 Yas Grubu Kadinlarda, Trichomonas vaginalis ve Diger Mikroorganizmalarin Vajinal Akinti Örneklerinden Mikroskobik Olarak Incelenmesi.

OBJECTIVE: Trichomonas vaginalis is a protozoon that causes trichomoniasis which is characterised by a foamy yellowish odorous discharge and superficial defects and necrotic ulcers in vaginal mucosa. Trichomoniasis is transmitted from human to human by sexual contact and can be seen in almost every part of the world. The aim of this study was to determine the incidence of Trichomonas vaginalis in 18-45 years age group women with vaginal discharge complaints who applied to the Gynaecology Outpatient Clinic of Konya Social Insurance Instution Hospital during September 1-December 15 2003. METHODS: Samples were taken from posterior fornix of the vagina with the aid of a speculum and sterile cotton swabs. All the samples were examined by wet mount preparations, Gram and Giemsa staining method under the light microscope. RESULTS: Of seventy samples 6 (9%) were positive for Trichomonas vaginalis, 9 (13%) for Gardnerella vaginalis, one for Mobiluncus spp. and 11 (16%) for Candida spp. CONCLUSION: It is possible to say that, in spite of a definite diagnosis of trichomoniasis made by cultivation method, examining the vaginal smear by direct microscope also has an important role in the diagnosis of infection. Direct microscopic examination will help in deciding whether to begin the treatment of trichomoniasis.

Candida albicans and bacterial vaginosis can coexist on Pap smears.

OBJECTIVE: The aim of our study was to study the relationship of blastospores and pseudohyphae in Papanicolaou (Pap) smears and Nugent scores for bacterial vaginosis (BV). STUDY DESIGN: A total of 471 Pap smears with Candida albicans were reviewed. The presence of blastospores and pseudohyphae was established. The Pap smears were restained with the Gram stain method to evaluate the bacterial flora according to the Nugent scoring system. RESULTS: Of the 471 Pap smears, blastospores and pseudohyphae were observed in 62.8% (296/471) and 37.2% (175/471) of the smears, and displayed symptoms in 4.4% (13/296) and 43.4% (76/175), respectively. A significant difference was found between these 2 groups (p < 0.0001). A positive BV Nugent score (≥ 7) was found in 22.1% (104/471) of the C. albicans cases. Blastospores and pseudohyphae with BV were 14.2% (42/296) and 35.4% (62/175), respectively. These high Nugent scores indicate statistically significant differences (p < 0.0001). CONCLUSION: C. albicans and BV can coexist. The presence of blastospores in these C. albicans cases was negatively related to symptoms.

Gram stains: a resource for retrospective analysis of bacterial pathogens in clinical studies.

We demonstrate the feasibility of using qPCR on DNA extracted from vaginal Gram stain slides to estimate the presence and relative abundance of specific bacterial pathogens. We first tested Gram stained slides spiked with a mix of 10(8) cfu/ml of Escherichia coli and 10(5) cfu/ml of Lactobacillus acidophilus. Primers were designed for amplification of total and species-specific bacterial DNA based on 16S ribosomal gene regions. Sample DNA was pre-amplified with nearly full length 16S rDNA ribosomal gene fragment, followed by quantitative PCR with genera and species-specific 16S rDNA primers. Pre-amplification PCR increased the bacterial amounts; relative proportions of Escherichia coli and Lactobacillus recovered from spiked slides remained unchanged. We applied this method to forty two archived Gram stained slides available from a clinical trial of cerclage in pregnant women at high risk of preterm birth. We found a high correlation between Nugent scores based on bacterial morphology of Lactobacillus, Gardenerella and Mobiluncus and amounts of quantitative PCR estimated genus specific DNA (rrn copies) from Gram stained slides. Testing of a convenience sample of eight paired vaginal swabs and Gram stains freshly collected from healthy women found similar qPCR generated estimates of Lactobacillus proportions from Gram stained slides and vaginal swabs. Archived Gram stained slides collected from large scale epidemiologic and clinical studies represent a valuable, untapped resource for research on the composition of bacterial communities that colonize human mucosal surfaces.

[Evaluation of efficacy of ketoconazole 800 mg-clindamycin 100 mg tablets vaginal against ketoconazole 800 mg- clindamycin 100 mg vaginal capsules in candida vaginitis and vaginosis]. / Evaluación de la eficacia de ketoconazol 800 mg-clindamicina 100 mg tabletas vaginales, contra ketoconazol 800 mg-100 mg de clindamicina cápsulas vaginales en vaginitis candidiásica y vaginosis.

BACKGROUND: pharmaceutical forms (presentations) influence treatment compliance and therefore the effectiveness. Here we present the results in the relief of vaginitis and vaginosis with two different dosage forms. OBJECTIVE: To compare the efficacy and safety of a combination of ketoconazole 800 mg + clindamycin in soft vaginal gel capsules 100 mg (vaginal capsules) against ketoconazole 800 mg + 100 mg clindamycin vaginal tablets (TV) in the management of vaginitis by C. albicans and/or vaginosis. MATERIAL AND METHOD: In a randomized, multicenter, comparative open label study, patients between 18 and 60 years with a diagnosis of vaginitis by C. albicans and/or vaginosis were included. Patients were evaluated clinically and direct exam of genital discharge and culture were performed. Patients were randomized to one of two treatments vaginal tablets or vaginal capsules, for 3 days. RESULTS: one hundred an sitxty nine patients were included, 85 in TV Group and 84 in vaginal capsules group. We found significant statistical difference in clinical response for tablet group at day three for burning p = 0.032 and itching p = 0.043. Microbiological cure was observed in patients with vaginitis by C. albicans, 92.5% in Group TV vs. 90.47% vaginal capsules group, all patients with G. vaginalis at baseline were negative for the organism at the end of the study, cure in patients with mixed infections were 78.94% for TV group vs. 78.26% vaginal capsules; group no adverse events were reported during treatment. CONCLUSIONS: Treatment of vaginitis/vaginosis with vaginal tablets is clinically better than vaginal soft gelatin capsules both treatments were well tolerated.

Vaginal flora changes on Pap smears after insertion of levonorgestrel-releasing intrauterine device.

BACKGROUND: The levonorgestrel intrauterine system (LNG-IUS) combines a uterine foreign body and the continuous release of low-dose levonorgestrel for contraception. Its influence on the rate of vulvovaginal infections and flora disturbance is insufficiently known, but important for contraceptive advice in women, especially those who develop recurrent vaginosis or Candida vulvovaginitis. STUDY DESIGN: Slides of 286 women who had a Pap smear taken before and 1 to 2 years after placement of a LNG-IUS were blindly reviewed for the presence of abnormal vaginal flora (AVF), bacterial vaginosis (BV), aerobic vaginitis (AV) and Candida vaginitis (CV). RESULTS: Prior to insertion, there were no differences in vaginal flora abnormalities between women using different kinds of contraception. LNG-IUS users did not have different rates of AVF, BV, AV or CV, but the general risk to develop any infection was increased. Uterine bleeding after insertion did not seem to predict a different flora type. CONCLUSION: We found that Pap smears suggested more vaginal infections after 1 year of LNG-IUS use than prior to insertion of the device.

Microbiological findings in subjects with asymptomatic oral lichen planus: a cross-sectional comparative study.

BACKGROUND: The bacterial colonization of the oral mucosa was evaluated in patients with asymptomatic oral lichen planus (OLP) and compared to the microbiologic status in mucosally healthy subjects. METHODS: Bacteria from patients with clinically and histopathologically diagnosed OLP from the Stomatology Service, Department of Oral Surgery and Stomatology, School of Dental Medicine, University of Bern, were collected with a non-invasive swab system. Samples were taken from OLP lesions on the gingiva and from non-affected sites on the contralateral side of the mouth. The control population did not have OLP and was recruited from the student clinic. All samples were processed with the checkerboard DNA-DNA hybridization method using well-defined bacterial species for the analysis. RESULTS: Significantly higher bacterial counts of Bacteroides ureolyticus (P = 0.001), Dialister species (sp.) (P = 0.006), Staphylococcus haemolyticus (P = 0.007), and Streptococcus agalactiae (P = 0.006) were found in samples taken from OLP lesions compared to sites with no clinical evidence of OLP. Significantly higher bacterial counts were found for Capnocytophaga sputigena, Eikenella corrodens, Lactobacillus crispatus, Mobiluncus curtisii, Neisseria mucosa, Prevotella bivia, Prevotella intermedia, and S. agalactiae at sites with lesions in subjects with OLP compared to sites in control subjects (P <0.001). CONCLUSIONS: Microbiologic differences were found between sites with OLP and sites in subjects without a diagnosis of OLP. Specifically, higher counts of staphylococci and S. agalactiae were found in OLP lesions.

Molecular quantification of Gardnerella vaginalis and Atopobium vaginae loads to predict bacterial vaginosis.

BACKGROUND: Bacterial vaginosis (BV) is a poorly detected public health problem that is associated with preterm delivery and for which no reliable diagnostic tool exists. METHODS: Molecular analysis of 231 vaginal samples, classified by Gram stain-based Nugent score, was used to propose molecular criteria for BV; these criteria were prospectively applied to 56 new samples. A quantitative molecular tool targeting 8 BV-related microorganisms and a human gene was developed using a specific real-time polymerase chain reaction assay and serial dilutions of a plasmid suspension. The targeted microorganisms were Gardnerella vaginalis, Lactobacillus species, Mobiluncus curtisii, Mobiluncus mulieris, and Candida albicans (which can be identified by Gram staining), as well as Atopobium vaginae, Mycoplasma hominis, and Ureaplasma urealyticum (which cannot be detected by Gram staining). RESULTS: With use of the Nugent score, 167 samples were classified as normal, 20 were classified as BV, and 44 were classified as intermediate. Except for U. urealyticum, M. mulieris, and Lactobacillus species, DNA of the tested bacteria was detected more frequently in samples demonstrating BV, but the predictive value of such detection was low. The molecular quantification of A. vaginae (DNA level, > or = 10(8) copies/mL) and G. vaginalis (DNA level, > or = 10(9) copies/mL) had the highest predictive value for the diagnosis of BV, with excellent sensitivity (95%), specificity (99%), and positive (95%) and negative (99%) predictive values; 25 (57%) of the samples demonstrating intermediate flora had a BV profile. When applied prospectively, our molecular criteria had total positive and negative predictive values of 96% and 99%, respectively. CONCLUSIONS: We report a highly reproducible, quantitative tool to objectively analyze vaginal flora that uses cutoff values for the concentrations of A. vaginae and G. vaginalis to establish the molecular diagnosis of BV.

Mobiluncus curtisii bacteremia.

Mobiluncus curtisii was isolated from the blood of a 35-year-old man with a medical history of ulcerative colitis who was admitted unconscious to the Intensive Care Unit (ICU). A CT scan revealed massive intracerebral hemorrhage in the left hemisphere. Temperature remained constant over 38.5 degrees C; therefore, two sets of blood cultures were collected. One anaerobic bottle BacT/ALERT SN (bioMerieux, France) was detected as positive after 5 days of incubation and a Gram stain confirmed a gram variable curved-shaped rod. The patient died 18 h after being admitted to the hospital.
