Nonspecific infection of the female reproductive system continues to occupy the first place among pathologies of the reproductive tract of the female. These diseases affect the organs and tissues related to the reproductive system. Using the method of polymerase chain reaction in real time, we investigated characteristics of the normal and conditionally pathogenic aerobic / facultative anaerobic, anaerobic biota in the urethra, cervical canal and vagina of women aged 16 to 58 years, studies were carried out on the basis of the Center of Laboratory Diagnostics, LLC "MEDLAYF". For all women up to the age of 40, biota is mainly represented by lactobacilli (Lactobacillus spp.), and in pathological complications of the urogenital tract of women the microbial composition of the biocoenosis is characterized by a decrease in the number of lactobacilli and their replacement by pathogenic anaerobic microorganisms. In disorders of the microflora of the urogenital tract we also detected the human papillomavirus of both high and low carcinogenic risk and Ureoplasma (urealiticum + parvum), Chlamydia trachomatis, Trichomonas vaginalis, Mycoplasma hominis and yeast of the genus Candida spp. The most frequently distributed of the most common causative agents of pathological conditions of the reproductive system of women is the human papillomavirus of high carcinogenic risk, Ureoplasma (urealiticum + parvum) and Candida spp. This is due to anatomical and physiological characteristics of the genital organs, hormonal and immune system.

Objective: The aim of this study was to assess the correlation between atypical squamous cells (ASC) and inflammatory infiltrate and vaginal microbiota using cervical liquid-based cytological (SurePath®) and high-risk human papillomavirus (HR-HPV) tests. Study Design: A cross-sectional study was conducted using a 6-year database from a laboratory in Fortaleza (Brazil). Files from 1,346 ASC cases were divided into subgroups and results concerning inflammation and vaginal microorganisms diagnosed by cytology were compared with HR-HPV test results. Results: An absence of specific microorganisms (ASM) was the most frequent finding (ASC of undetermined significance, ASC-US = 74%; ASC - cannot exclude high-grade squamous intraepithelial lesion, ASC-H = 68%), followed by bacterial vaginosis (ASC-US = 20%; ASC- H = 25%) and Candida spp. (ASC-US = 6%; ASC-H = 5%). Leukocyte infiltrate was present in 71% of ASC-US and 85% of ASC-H (p = 0.0040), and in these specific cases HR-HPV tests were positive for 65 and 64%, respectively. A positive HR-HPV test was relatively more frequent when a specific microorganism was present, and Candida spp. was associated with HR-HPV-positive results (p = 0.0156), while an ASM was associated with negative HR-HPV results (p = 0.0370). Conclusion: ASC-US is associated with an absence of inflammation or vaginosis, while ASC-H smears are associated with Trichomonas vaginalis and inflammatory infiltrate. A positive HR-HPV is associated with Candida spp. in ASC cytology.

Abstract Background How vaginal infections such as bacterial vaginosis, Candida spp, and Trichomonas vaginalis affect persistence of human papillomavirus (HPV) infection is not well established. Our study aimed to evaluate the association between common vaginal infections and cervical non-HPV16/18 infection, as risk factors associated with persistence of nonvaccine HPV types will become increasingly relevant in the setting of HPV vaccination. Methods We performed an analysis in 2039 AS04-HPV16/18–vaccinated women enrolled in a phase II/III trial in China, who were HPV DNA negative at month 0 and 6 and had at least 1 subsequent follow-up visit. Vaginal infections were detected in liquid-based cytology according to the diagnostic criteria of the Bethesda System. Associations between vaginal infections and incident and 6-month persistent non-HPV16/18 infections in the cervix were evaluated using generalized estimating equations, adjusting for the age at initial vaccination, as well as HPV types in the persistence analysis. Results Study visits with any vaginal infection had a statistically significant increased risk of incident non-HPV16/18 infection compared to those without vaginal infections (odds ratio [OR], 1.44 [95% confidence interval {CI}, 1.09–1.92]). However, vaginal infections were not associated with 6-month persistent non-HPV16/18 infection (OR, 1.02 [95% CI, .62–1.69]). Conclusions Our study suggests that common vaginal infections are not associated with persistence of non-HPV16/18 infection among HPV16/18-vaccinated women.

The purpose of the review a synthesis of research data on the role of human papillomavirus infection in the reproductive health of women and men. Key Points. Human papillomavirus (HPV) is one of the most common sexually transmitted viruses worldwide. According to the World Health Organization, HPV is the main cause of the development of HPV-associated diseases among both women and men. Viruses are subdivided into HPV with low carcinogenic risk, which cause benign warts, and HPV with high carcinogenic risk, which cause cancer. Different types of human papillomaviruses depending on their characteristic tropism, are divided into skin and mucous types. Viral infection in men leads to a decrease in the quality of sperm (for example, asthenozoospermia) due to apoptosis in sperm cells and due to the development of antisperm immunity. A negative viral effect on the fertility of women is manifested in an increase in the frequency of spontaneous miscarriages and a premature rupture of the amniotic membranes during pregnancy. There is evidence that HPV decreases the number of trophoblastic cells and abnormal trophoblastic-endometrial adhesion is also observed. In trophoblastic cells transfected with high-risk HPV, the level of apoptosis increases. HPV vaccination is safe, and the results show not only protection against HPV-associated diseases in women and men, but also a reduction of gestational complications, reduced preterm birth rates and the protection of newborns from infection.

This study investigated the effects of different levels of methionine (Met) in a low protein diet on the production performance, reproductive system, metabolism, and gut microbial composition of laying hens to reveal the underlying molecular mechanism of Met in a low protein diet on the host metabolism and gut microbial composition and function of hens. A total of 360 healthy 38-week-old Peking Pink laying hens with similar body conditions and egg production (EP) were randomly divided into four groups with nine replicates per treatment and 10 hens per replicate. The hens in each treatment group were fed low protein diets containing different levels of Met (0.25, 0.31, 0.38, and 0.47%, respectively) for 12 weeks. Feed and water were provided ad libitum throughout the trial period. The results showed that, compared with the 0.25% Met group, the final body weight (FBW), average daily gain (ADG), EP, egg weight (EW), and average daily feed intake (ADFI) in the other groups were significantly increased and feed egg ratio (FER) was decreased. Meanwhile, the EW and yield of abdominal fat (AFY) in the 0.47% Met group were higher than those in other groups. The triglyceride (TG), estradiol (E2), total protein (TP), albumin (ALB), and immunoglobulin A (IgA) in the 0.38 and 0.47% Met groups were higher than those in other groups. In addition, 16S rRNA gene sequencing revealed that there was no difference in the Sobs index, ACE index, and Shannon index among all groups. However, it is worth noting that feeding low protein diets with Met changed the gut microbial composition (e.g., the supplementation of Met increased the level of Lactobacillus and decreased the proportion of Faecalibacterium). Also, our results showed that the changes in gut microbial composition induced by the diets with different levels of Met were closely related to the changes of key parameters: ADFI, EW, FBW, TG, EM, EP, ADG, FER, and uric acid (UA). Our results highlight the role of adding an appropriate amount of Met to the low protein diet in laying hens, which could improve the gut microbial composition, production performance, reproductive system, and nutrient metabolism of laying hens. In conclusion, this study suggested that when the Met level was 0.38%, the production performance of the laying hens was pretty good.
