Interferon-ε as potential inhibitor of Chlamydia trachomatis infection.

Chlamydia trachomatis, the main cause of bacterial sexually transmitted diseases, is responsible for severe reproductive sequelae. Amongst all the cytokines involved in host immunity towards this pathogen, IFN-ε has recently acquired importance for its potential contribution to the female reproductive tract innate defenses. Herein, our study aimed to explore, for the first time, the activity of IFN-ε toward C. trachomatis in an in vitro infection model, by testing its effects on the different phases of chlamydial developmental cycle, as well as on the ultrastructural characteristics of chlamydial inclusions, via transmission electron microscopy. Main result is the capability of IFN-ε to alter C. trachomatis growth, as suggested by reduced infectious progenies, as well as a patchy distribution of bacteria and altered morphology of reticulate bodies within inclusions. In conclusion, our results suggest that IFN-ε could play a role in the innate and adaptive immune defenses against C. trachomatis; in the future, it will be needed to investigate its activity on an infection model more closely resembling the physiological environment of the female genital tract.

SGLT2 Inhibitors and Safety in Older Patients.

SGLT2 inhibitors (SGLT2i) are effective in the management of diabetes and in reducing adverse cardiovascular and renal outcomes. Randomized clinical trials demonstrated safety and tolerability in older adults. Adverse effects associated with SGLT2i are impacted by patient frailty, comorbidities, and concomitant medication use and, therefore, must be thoroughly evaluated before initiating treatment. The risk of volume depletion, hypoglycemia, genital infections, and diabetic ketoacidosis can be minimized by appropriate patient selection, patient education, and early symptom recognition. Limited data exists regarding the risk of urinary tract infections, fractures, and amputations in the elderly treated with SGLT2i and routine monitoring is recommended.

Association between genital tract infection and premature rupture of membranes: A retrospective case control study in Tunisia, North Africa.

Premature Rupture of Membranes is responsible for most cases of neonatal death. In most of these cases, the causes of PROM have not been established in Tunisia, although several risk factors have been described. Therefore, we set out to determine the presence of an association between genital infections and PROM among Tunisian women. A case-control study was conducted among 251 womens to detect the presence of association between genital tract infection and Premature Rupture of Membranes.Cases had a premature membranes rupture and the controls had intact membranes or suffering from premature membrane rupture during the latent phase of labour. Data were collected from the medical register including socio-demographic characteristics, obstetrics, and medical history. Association between genital infections and premature rupture of membranes was estimated using the Odds Ratio and 95% CI. One risk factor was identified, including age. There is no association between the presence of Group B streptococcus (OR= 1.08; 95% CI 0.50-2.34), presence of Trichomonasvaginalis (OR= 2.45; 95% CI 0.15-39.83) and presence of Candidiasis (OR= 1.11; 95% CI 0.58-2.14) and premature rupture of membranes. Co-infection was not associated with premature rupture of membranes (OR= 0.43; 95% CI 0.45-6.07). There is no association between genital infections and PROM among pregnant Tunisian women.

Safety of dapagliflozin in a broad population of patients with type 2 diabetes: Analyses from the DECLARE-TIMI 58 study.

AIMS: To evaluate comprehensively the safety of dapagliflozin in patients with type 2 diabetes (T2DM), with emphasis placed on potential safety concerns related to the sodium-glucose co-transporter-2 inhibitor class. METHODS: In the Dapagliflozin Effect on Cardiovascular Events - Thrombolysis in Myocardial Infarction 58 (DECLARE-TIMI 58) study, 17 160 patients with T2DM were randomized to dapagliflozin or placebo and followed for a median of 4.2 years. Safety was evaluated in 17 143 patients receiving at least one dose of study drug. RESULTS: Acute kidney injury occurred less frequently with dapagliflozin, and adverse events suggestive of volume depletion were balanced between treatment groups, both irrespective of baseline estimated glomerular filtration rate, blood pressure, diuretic or loop diuretic use (interaction P values >0.05). Fractures and malignancies were balanced between the groups, irrespective of sex, diabetes duration or smoking (interaction P values >0.05) and fewer cases of bladder cancer occurred in the dapagliflozin versus the placebo group. Diabetic ketoacidosis was very rare, but more frequent with dapagliflozin versus placebo (27 vs. 12 patients with events; P = 0.02), yet signs, symptoms and contributing factors were similar in the two groups. Major hypoglycaemia occurred less frequently with dapagliflozin versus placebo, regardless of baseline use of either insulin or sulphonylureas (interaction P values >0.05). There were more adverse events of genital infections leading to discontinuation of study drug in the dapagliflozin versus the placebo group, but serious genital infections were few and balanced between treatment groups. Urinary tract infections, acute pyelonephritis and urosepsis were also balanced between treatment groups. CONCLUSIONS: Dapagliflozin was well tolerated. The long duration and large number of patient-years in DECLARE-TIMI 58 comprehensively addressed previous safety questions, confirming the robust safety profile of dapagliflozin.

Single-Cell Sequencing in Human Genital Infections.

Human genital infections are one of the most concerning issues worldwide and can be categorized into sexually transmitted, urinary tract and vaginal infections. These infections, if left untreated, can disseminate to the other parts of the body and cause more complicated illnesses such as pelvic inflammatory disease, urethritis, and anogenital cancers. The effective treatment against these infections is further complicated by the emergence of antimicrobial resistance in the genital infection causing pathogens. Furthermore, the development and applications of single-cell sequencing technologies have open new possibilities to study the drug resistant clones, cell to cell variations, the discovery of acquired drug resistance mutations, transcriptional diversity of a pathogen across different infection stages, to identify rare cell types and investigate different cellular states of genital infection causing pathogens, and to develop novel therapeutical strategies. In this chapter, I will provide a complete review of the applications of single-cell sequencing in human genital infections before discussing their limitations and challenges.

Genital and extra-genital Chlamydia trachomatis and Neisseria gonorrhoeae infections in young women attending a Sexually Transmitted Infections (STI) clinic.

Chlamydia trachomatis and Neisseria gonorrhoeae are the most common agents of bacterial sexually transmitted infections (STIs) worldwide. Here, we evaluated genital and extra-genital C. trachomatis and N. gonorrhoeae infection prevalence in a cohort of young women attending an STI Outpatients Clinic in Italy. From May 2019 to December 2019, 134 women aged 18-26 years were enrolled. A vaginal, a pharyngeal and a rectal swab for the molecular detection of C. trachomatis and N. gonorrhoeae were collected from each patient. Chlamydia-positive samples underwent a molecular genotyping based on pmpH gene. Total prevalence of C. trachomatis and N. gonorrhoeae infections was 17.9% and 11.2%, respectively. Chlamydial infections were prevalent in the urogenital (16.4%) and rectal (13.4%) sites, whereas N. gonorrhoeae predominated in the genital (7.4%) and pharyngeal (6%) mucosa. Overall, 5.2% of cases would have been missed if extra-genital sites had not been tested. Notably, 60% of women with a rectal infection did not report anal sex. A history of sexual contacts with a positive partner (P=0.03) and a history of ≥3 partners in the last 6 months (P=0.0075) were highly predictive of a bacterial STI. No cases of lymphogranuloma venereum were found. These data could help set up effective strategies to prevent the spread of STIs.

Adverse Effects of Glycemia-Lowering Medications in Type 2 Diabetes.

PURPOSE OF REVIEW: Treatment of patients with type 2 diabetes mellitus is focused on preventing the occurrence and delaying the development of macro- and micro-vascular complications. Glycemic control can help prevent these complications, but there is concern about the adverse effects of glycemia-lowering medications. A rational approach is to balance the desired low risk of adverse events against the unwanted higher risk of major complications resulting from suboptimal glucose control. RECENT FINDINGS: Using the above approach, approved glucose-lowering agents have favorable benefit-to-risk profiles for use in most patients with type 2 diabetes. We first briefly review the mechanism of actions and benefits of the different commonly used classes of glycemia-lowering medications and then discuss adverse effects and safety concern associated with their use. Our overall assessment is that if used appropriately, the different classes of glycemia-lowering medications offer beneficial outcomes with relatively modest and, in some instances, preventable adverse events.

Bartholinitis due to Aggregatibacter aphrophilus: a case report.

BACKGROUND: Aggregatibacter aphrophilus, a commensal of the oro-pharyngeal flora and member of the HACEK group of organisms, is an uncommonly encountered clinical pathogen. It has already been described as the causative agent of brain abscesses, empyema, meningitis, sinusitis, otitis media, bacteriemia, pneumonia, osteomyelitis, peritonitis, endocarditis and wound infections. Herein we report the first case of bartholinitis due to A. aphrophilus. CASE PRESENTATION: A 33-year-old woman was admitted for a 3-day genital pain without fever and urinary functional signs. The abscess was incised and drained; A. aphrophilus was the only micro-organism that grew from the pus. The patient received no antibiotics; the clinical course was favourable. CONCLUSION: This case highlights the importance of an effective treatment of recurrent bartholinitis such as a cold resection of the gland. It is presented for its rarity.

Effects of vaginal lactobacilli in Chlamydia trachomatis infection.

Increasing evidence indicates that abnormal vaginal flora lacking lactobacilli facilitates the acquisition of several sexually transmitted diseases including Chlamydia trachomatis. C. trachomatis, the most common bacterial agent of genital infections worldwide, can progress from the lower to upper reproductive tract and induce severe sequelae. The ability of C. trachomatis to develop into a persistent form has been suggested as key pathogenetic mechanism underlying chronic infections and sequelae. The aim of our study was to investigate the C. trachomatis interaction with vaginal microbiota analyzing the effects of Lactobacillus strains (L. brevis and L. salivarius) on the different phases of C. trachomatis developmental cycle. In addition, the effect of lactobacilli on persistent chlamydial forms induced by HSV-2 coinfection has also been evaluated. Our results demonstrated significant inhibition of C. trachomatis multiplication by vaginal lactobacilli. L. brevis was significantly more effective than L. salivarius (p<0.05) on all the steps of chlamydial infection cycle suggesting that the ability of lactobacilli to protect from infection is strain-dependent. Lactobacilli had an adverse effect on elementary chlamydial bodies (p<0.05), on chlamydial adsorption to epithelial cells (p<0.001) and on intracellular phases of chlamydial replication (p<0.0001). Our study also demonstrated a protective effect of lactobacilli toward persistent C. trachomatis forms induced by HSV-2 coinfection. A significant increase in the production of C. trachomatis infectious progeny was observed in C. trachomatis/HSV-2 coinfection in the presence of L. brevis (p=0.01) despite a significant inhibition of C. trachomatis multiplication (p=0.028). Our data suggest that a healthy vaginal microbiota can reduce the risk of acquiring C. trachomatis infection and counteract the development of persistent chlamydial forms.

Impact of Genital Infections and Antibiotic Use on Incidence of Preterm Birth: A Retrospective Observational Study.

This study investigates the complex interplay among genital infections, antibiotic usage, and preterm birth. This study aims to identify common genital pathogens associated with preterm births, assess the impact of various antibiotic treatments on pregnancy outcomes, and understand antibiotic resistance patterns among these pathogens. This study included 71 pregnant women who experienced preterm birth and 94 women with genital infections who delivered at term. Various maternal characteristics, medical history, signs and symptoms, gestational weight, gestational age, type of birth, vaginal pH, Nugent scores, and vaginal flora were analyzed. Antibiotic resistance patterns of isolated microorganisms were also examined. The prevalence of sexually transmitted diseases (STDs) and genital herpes was significantly higher in the preterm group. Preterm births were associated with fever, pelvic pain, vaginal spotting, and fatigue. Vaginal pH levels and Nugent scores were significantly higher in the preterm group, indicating disturbed vaginal flora. The presence of Extended-Spectrum Beta-Lactamases (ESBLs) was a particularly strong risk factor, increasing by more than four times the odds of preterm birth (OR = 4.45, p = 0.001). Vancomycin-Resistant Enterococci (VRE) presence was another critical factor, with a four-fold increase in the odds of preterm birth (OR = 4.01, p = 0.034). The overall presence of Multidrug-Resistant (MDR) organisms significantly increased the odds of preterm birth (OR = 3.73, p = 0.001). Specific pathogens like Chlamydia trachomatis (OR = 3.12, p = 0.020) and Mycoplasma hominis (OR = 3.64, p = 0.006) were also identified as significant risk factors. Ureaplasma urealyticum also showed a significantly higher risk of preterm birth (OR = 2.76, p = 0.009). This study highlights the importance of screening for and treating genital infections during pregnancy, especially STDs and genital herpes, as they can significantly increase the risk of preterm birth. Additionally, the presence of specific microorganisms and antibiotic resistance patterns plays an essential role in preterm birth risk. Early detection and targeted antibiotic treatment may help mitigate this risk and improve pregnancy outcomes.

Antimicrobial Resistance of Genital Mycoplasma and Ureaplasma: A Multicentre Study Over a 5-Year Period in Italy (2017-2021).

Updated data on genital Mollicutes prevalence and antimicrobial susceptibility can help provide guidance for antibiotic stewardship and set up effective strategies for infection control policies. In this multicentre study, we assessed the prevalence and the resistance profile of Mycoplasma hominis (MH) and Ureaplasma species (U. parvum/U. urealyticum), analyzing data from 21,210 subjects who provided urogenital samples for Mollicutes detection by culture over a 5-year period (2017-2021) in two high-density urban areas in the North of Italy (i.e., Bologna and Lecco). Overall prevalence of Mollicutes infection was 22.3%, with women showing a significantly higher detection rate than men (p < 0.00001). The prevalence decreased with age (highest prevalence <30 years) and over the years considered. Ureaplasma strains were much more frequently detected (62.3%) compared to MH (8.3%) and to mixed infections (29.4%). Ureaplasma species showed high levels of ciprofloxacin resistance (39.5%), whereas MH strains were nonsusceptible to azithromycin and roxithromycin in about 60% of cases. Over time, a significant decrease of resistance to azithromycin and doxycycline was detected (p < 0.0001 and 0.0004, respectively), in parallel with an important increase of ciprofloxacin-resistance levels (p < 0.0001). Overall, our results revealed that minocycline and josamycin can be first-line drugs for Mollicutes empirical treatment.

The Presence of Lactobacillus spp. and its Effect on the Occurrence of Other Microorganisms in the Reproductive Tract of Polish Women.

Disorders of the vaginal microbiota can lead to many complications and affect fertility. This study evaluates the role of Lactobacillus in the vagina and its impact on the incidence of colonization by pathogenic microorganisms, analyzing the results of 1,039 women of reproductive age (18-49 years) who underwent a microbiological examination of the reproductive tract in 2020. Samples were examined by microscopy, culture, and NAAT. As the number of Lactobacillus increases, the chance of developing symptoms decreases. In fact, it has been shown that the higher the number of Lactobacillus spp. the less frequently Gardnerella vaginalis and Streptococcus group B are observed. As the concentration of Lactobacillus spp. increases by one category, the risk of G. vaginalis after adjustment to age and pH decreases by 80% (p < 0.001). Similarly, the correlation between Lactobacillus spp. and vaginal pH was shown. After adjustment to age, the odds of prevalence pH > 4.5 for people with Lactobacillus category higher 1 is 76% lower.

The role of bacterial genital infections in spontaneous preterm delivery: a case-control study.

Background: Spontaneous preterm delivery is defined as the beginning of the birth process before the 37th week of pregnancy. The presence of microorganisms in the fetal membranes is accompanied by an increase in the production of prostaglandin, one of the important factors associated with the prevalence of preterm birth. The invasion of microorganisms leads to the production of protease, coagulase, and elastase, which directly stimulate the onset of childbirth. We investigated the role of genital infections in women with preterm birth. Methods: The present case-control study was conducted in the west of Iran on 100 women with spontaneous preterm delivery (following 24 weeks of gestation and before 36 weeks and 6 days) as the case group and 100 women with normal delivery as controls. A questionnaire was applied to collect the data. Polymerase chain reaction and pathological examination of the placenta were performed. Results: The average age in women with normal delivery (30.92 ± 5.10) in women with spontaneous preterm delivery (30.27 ± 4.93). The prevalence of Chlamydia trachomatis, Neisseria gonorrhea, Listeria monocytogenes, and Mycoplasma genitalium infections was zero in both groups. The highest prevalence of Gardnerella vaginalis was 19 (19%) in the case group and Ureaplasma parvum 15 (15%) in the control group. Also, Placental inflammation was zero in controls and 7(7%) in the patient group. There was a significant relationship between Gardnerella vaginalis bacteria and spontaneous preterm delivery. Conclusion: The results of our study showed that except for Gardnerella vaginalis bacteria, there is no significant relationship between the above bacterial infections and spontaneous preterm birth. Moreover, despite the significant reduction in the prevalence of many sexually transmitted infections in this research, it is still suggested to increase the awareness of people, including pregnant women, about the ways it can be transmitted by gynecologists and health and treatment centers.

Risk of Diabetic Ketoacidosis Associated with Sodium Glucose Cotransporter-2 Inhibitors: A Network Meta-Analysis and Meta-Regression.

Background: Sodium glucose cotransporter-2 inhibitors (SGLT2is) represent an emerging class of drugs with diverse indications. Despite their therapeutic potential, concerns regarding safety, particularly diabetic ketoacidosis (DKA), remain contentious, with uncertainty regarding differences among various SGLT2is. This study aimed to conduct a network meta-analysis and meta-regression to evaluate the risk of SGLT2i-induced DKA and associated factors. Methods: We systematically searched electronic databases for randomized clinical trials assessing SGLT2is across indications, reporting incidences of DKA. Mixed treatment comparison pooled estimates (MTCPEs) were calculated, and odds ratios (OR) with 95% confidence intervals (95% CI) served as effect estimates. We analyzed differences across dose categories (low, medium, and high) and conducted a meta-regression analysis to identify risk factors. The strength of evidence for key comparisons was determined. Results: Our analysis included 73 articles encompassing 85,997 participants assessing the risk of DKA. SGLT2is were associated with a heightened risk of DKA compared to placebo/control interventions (OR: 1.83; 95% CI: 1.35, 2.46), a finding confirmed by bootstrap analysis. Among SGLT2is, dapagliflozin (OR: 1.9; 95% CI: 1.17, 3.08), sotagliflozin (OR: 1.93; 95% CI: 1.14, 3.25), canagliflozin (OR: 1.11; 95% CI: 1.11, 12.45), and ertugliflozin (OR: 3.92; 95% CI: 1.04, 14.77) exhibited increased DKA risk. No significant differences were observed among specific SGLT2is. Sub-group analyses revealed a high risk of DKA with low (OR: 1.98; 95% CI: 1.3, 2.95) and high doses (OR: 2.4; 95% CI: 1.7, 3.3), type 1 diabetes (OR: 3.6; 95% CI: 1.6, 8.1), type 2 diabetes (OR: 1.6; 95% CI: 1.3, 2.4), as well as a diabetes duration exceeding 10 years (OR: 3.4; 95% CI: 1.1, 10.8). The evidence of certainty for most comparisons was moderate. Conclusions: SGLT2 inhibitors (SGLT2is) have been found to elevate the risk of DKA. The key factors that significantly predict the likelihood of DKA include the presence of diabetes (whether T1D or T2D) and the duration of diabetes. Based on these findings, standard treatment guidelines should advise taking specific precautions against DKA in patients identified as high-risk.

Genito-urinary infectious adverse events related to sodium glucose cotransporter-2 inhibitors: a network meta-analysis and meta-regression.

INTRODUCTION: Sodium glucose cotransporter-2 inhibitors (SGLT2is) are an emerging class of drugs with wide indications. Controversial evidence exists regarding the risk of urinary tract infection (UTI) and genital infections (GI) with SGLT2is paving way for undertaking this network meta-analysis and meta-regression study. METHODS: Data from randomized trials evaluating SGLT2is reporting the number of patients with UTI and GI were included. Odds ratios (OR) with 95% confidence intervals (95% CI) were the effect estimates. Meta-regression analysis identified risk factors. Number needed to harm (NNH) was estimated. RESULTS: Two hundred and sixty-four articles were included [UTI (213 studies; 150,140 participants) and GI (188 studies; 121,275 participants)]. An increased risk of UTI (OR: 1.11; 95% CI: 1.06, 1.16) and GI (OR: 3.5, 95% CI: 3.1, 3.9) was observed. Men showed a lower risk of UTI (OR: 0.2; 95% CI: 0.2, 0.3) and GI (OR: 0.4; 95% CI: 0.4, 0.5). Meta-regression analyses revealed BMI ≥ 30 kg/m2 and duration of SGLT2i treatment for ≥6 months as risk factors. NNH was 16 for UTI and 25 for GI. CONCLUSION: SGLT2is increase the risk of UTI and GI that needs to be incorporated in the treatment guidelines with precautions in high-risk patients.

Deciphering the Puzzle: Literature Insights on Chlamydia trachomatis-Mediated Tumorigenesis, Paving the Way for Future Research.

Some infectious agents have the potential to cause specific modifications in the cellular microenvironment that could be propitious to the carcinogenesis process. Currently, there are specific viruses and bacteria, such as human papillomavirus (HPV) and Helicobacter pylori, that are well established as risk factors for neoplasia. Chlamydia trachomatis (CT) infections are one of the most common bacterial sexually transmitted infections worldwide, and recent European data confirmed a continuous rise across Europe. The infection is often asymptomatic in both sexes, requiring a screening program for early detection. Notwithstanding, not all countries in Europe have it. Chlamydia trachomatis can cause chronic and persistent infections, resulting in inflammation, and there are plausible biological mechanisms that link the genital infection with tumorigenesis. Herein, we aimed to understand the epidemiological and biological plausibility of CT genital infections causing endometrial, ovarian, and cervical tumors. Also, we covered some of the best suitable in vitro techniques that could be used to study this potential association. In addition, we defend the point of view of a personalized medicine strategy to treat those patients through the discovery of some biomarkers that could allow it. This review supports the need for the development of further fundamental studies in this area, in order to investigate and establish the role of chlamydial genital infections in oncogenesis.

Genital infection from Monkeypox virus requiring surgical debridement and scrotoplasty in an immunocompromised patient.

Background: Mpox is a zoonotic viral disease transmitted by close contact with infected individuals, contacting or eating infected animals, and now, sexual contact. The main treatment option for infected individuals is supportive care as no FDA-approved treatment exists. Case presentation: A 33-year-old male with HIV who contracted Mpox who developed a large painful genital ulcer with overlying eschar. He required surgical debridement of the penile ulcer followed by scrotoplasty. Conclusion: While local wound care plus antibiotics may be effective at managing some genital lesions, Urologists should consider surgical debridement with delayed reconstruction for progressive, non-healing wounds in these individuals.

Chlamydia trachomatis-An Emerging Old Entity?

Chlamydia trachomatis is an evasive pathogen that can prompt severe clinical manifestations in humans such as vaginitis, epididymitis, lymphogranuloma venereum, trachoma, conjunctivitis and pneumonia. If left untreated, chronic infections with C. trachomatis can give rise to long-lasting and even permanent sequelae. To shed some light on its widespread nature, data from original research, systematic reviews and meta-analyses from three databases was collected and analyzed in the context of chlamydial infection, related symptoms and appropriate treatment modalities. This review describes the bacterium's pervasiveness on a global scale, especially in developing countries, and suggests ways to halt its transmission and spread. Infections with C. trachomatis often go unnoticed, as many individuals are asymptomatic and unaware of their diagnosis, contributing to a delay in diagnosis and treatment. The high prevalence of chlamydial infection highlights the need for a universal screening and detection method enabling immediate treatment at its onset. Prognosis is favorable with antibiotic therapy and education for high-risk groups and their sexual partners. In the future, a quick, easily accessible, and inexpensive test should be developed to diagnose and treat infected individuals early on. Along with a vaccine against C. trachomatis, it would halt the transmission and spread of the pathogen worldwide.

Molecular Epidemiology of Genital Infections in Campania Region: A Retrospective Study.

This study provides updated information on the prevalence and co-infections caused by genital microorganisms and pathogens: Mycoplasma genitalium, Mycoplasma hominis, Ureaplasma parvum, Ureaplasma urealyticum, Trichomonas vaginalis, and Gardnerella vaginalis, by retrospectively analyzing a cohort of patients living in the Naples metropolitan area, Campania region, Southern Italy. To investigate the genital infections prevalence in clinical specimens (vaginal/endocervical swabs and urines) collected from infertile asymptomatic women and men from November 2018 to December 2020, we used a multiplex real-time PCR assay. Of the 717 specimens collected, 302 (42.1%) resulted positive for at least one of the targets named above. Statistically significant differences in genital prevalence of selected microorganisms were detected in both women (62.91%) and men (37.08%). G. vaginalis and U. parvum represented the most common findings with an 80.2% and 16.9% prevalence in vaginal/endocervical swabs and first-voided urines, respectively. Prevalence of multiple infections was 18.18% and 8.19% in women and men, respectively. The most frequent association detected was the co-infection of G. vaginalis and U. parvum with 60% prevalence. Our epidemiological analysis suggests different infection patterns between genders, highlighting the need to implement a preventative screening strategy of genital infections to reduce the complications on reproductive organs.

In vitro antimicrobial activity of selected essential oils against bacteria and yeasts isolated from the genital tract of mares.

The aim of the present study, the first to test clinical equine isolates, was to evaluate the antimicrobial activity of commercial essential oils (EOs) obtained from Origanum vulgare, Thymus vulgaris, Cinnamomum zeylanicum, Cymbopogon citratus, Aloysia triphylla and Syzygium aromaticum against Streptococcus spp., Staphylococcus spp., Candida albicans and Rhodotorula spp. previously isolated from uteri of mares with reproductive disorders. T. vulgaris showed the best antibacterial activity against all the selected agents, with MICs ranging from 0.07 mg/mL for S. equi subsp. zooepidemicus to 0.29 mg/mL versus Streptococcus sp. and Staphylococcus spp. isolates and versus C. albicans and Rhodotorula spp., with MICs of 0.46 mg/mL and 1.86 mg/mL, respectively. O. vulgare, S. aromaticum, C. zeylanicum EOs showed good antibacterial activity with MICs ranging from 0.07 mg/mL to 0.29 mg/mL, 0.16 mg/mL to 0.32 mg/mL, 0.07 mg/mL to 0.63 mg/mL, respectively; A. triphylla was the most active EO against Rhodotorula spp. (0.43 mg/mL).
