Medicine (Baltimore) 2024; 103:e37068. [PMID: 38335425 PMCID: PMC10860981 DOI: 10.1097/md.0000000000037068] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/04/2023] [Revised: 12/23/2023] [Accepted: 01/04/2024] [Indexed: 02/12/2024] Open
Abstract
This study aims to investigate the relationship between the human papillomavirus (HPV) infection and the altered vaginal microecological environment of patients. Initially, HPV genotyping and microecological detection were performed in 1281 subjects in the Department of Obstetrics and Gynecology of The First Hospital of Qinhuangdao (Qinhuangdao, China). The relationship between the enzymes of vaginal microecology, that is, proline aminopeptidase and acetylglucosaminidase, and vaginal inflammatory diseases, as well as the prognosis of HPV infection, was analyzed. The experimental findings indicated a close relationship between the expression of positive prolyl aminopeptidase and trichomonas vaginitis, as well as bacterial vaginitis. In addition, the expression of acetylglucosaminidase is closely associated with trichomonas vaginitis and vulvovaginal candidiasis. Furthermore, the observations indicated that positive prolyl aminopeptidase and acetylglucosaminidase could increase the risk of various subtypes of HPV infection in patients. The receiver operating characteristic curve analysis presented that the expression of prolyl aminopeptidase and acetylglucosaminidase could offer exceptional diagnostic efficacy, indicating their association with persistent HPV infection. In summary, our results highlighted that the expression of positive prolyl aminopeptidase and acetylglucosaminidase in the vaginal microecology could be substantially correlated to the occurrence and the development of vaginal inflammatory diseases, as well as the outcome and the risk of persistent HPV infection.

Abstract
Human papillomavirus (HPV) infection is a necessary but not sufficient condition for the development of cervical cancer. The dysbiotic shift in the cervicovaginal microbiome appears to be a major co-factor in carcinogenesis. New analytical methods, such as next-generation sequencing (NGS), can be used to detect all of the vaginal microorganisms present and therefore identify individual therapeutic options. The relationship of bacterial vaginosis and carcinogenesis, as well as possible indications for the use of microbiome analysis, will be discussed.

Abstract
OBJECTIVES The evidence in the literature regarding the relationship between Trichomonas vaginalis (TV) infection and cervical neoplasia is conflicting. The main aim of this study was to evaluate the magnitude of the risk of cervical neoplasia associated with TV infection. METHODS A meta-analysis of observational studies, which provided raw data on the association of TV infection with cervical neoplasia, was performed. For this aim, we searched scientific databases (PubMed/Medline, Scopus, the Web of Sciences, and Embase) from inception to March 15, 2023. A random-effects model was applied by Stata 17.0 to calculate the pooled and adjusted odds ratios (ORs) with 95% confidence intervals (CI), including subgroup, sensitivity, and cumulative analyses to explore sources of heterogeneity. RESULTS Of the 2584 records initially identified, 35 eligible studies contributed data for 67,856 women with cervical neoplasia, and 933,697 healthy controls from 14 countries were included. The pooled (2.15; 1.61-2.87; I2 = 87.7%) and adjusted (2.17; 1.82-2.60; I2 = 31.27%) ORs indicated a significant positive association between TV infection and the development of cervical neoplasia. There was no significant change in pooled and adjusted ORs by applying sensitivity and cumulative analyses, indicating the robustness of our findings. The pooled OR was significant in most sub-group analyses. There was no publication bias in the included studies. CONCLUSION Our findings indicated that women with a TV infection are at significantly greater risk of cervical neoplasia. Future research, particularly longitudinal and experimental studies, should be done to better understand the various aspects of this association.

BMC Complement Med Ther 2023; 23:212. [PMID: 37370057 DOI: 10.1186/s12906-023-04043-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2023] [Accepted: 06/15/2023] [Indexed: 06/29/2023] Open
Abstract
BACKGROUND Cervical cancer (CC) is a common gynecological malignancy with high morbidity worldwide. Butyrate, a short-chain fatty acid produced by intestinal flora, has been reported to inhibit cervical carcinogenesis. This study aimed to investigate the pro-apoptotic effects of butyrate on CC and the underlying mechanisms. METHODS Human HeLa and Ca Ski cells were used in this study. Cell proliferation, cell migration and invasion were detected by CCK-8 and EdU staining, transwell and wound healing assay, respectively. Cell cycle, mitochondrial membrane potential and apoptosis were evaluated by flow cytometry. Western blot and RT-qPCR were carried out to examine the related genes and proteins to the mitochondrial complex Ι and apoptosis. Metabolite changes were analyzed by energy metabolomics and assay kits. The association between G protein-coupled receptor 41, 43, 109a and CC prognosis was analyzed using data from The Cancer Genome Atlas (TCGA). RESULTS CCK-8 results showed significant inhibition of CC cell proliferation induced by butyrate treatment, which was confirmed by EdU staining and cell cycle detection. Data from the transwell and wound healing assay revealed that CC cell migration was dramatically reduced following butyrate treatment. Additionally, invasiveness was also decreased by butyrate. Western blot analysis showed that cleaved Caspase 3 and cleaved PARP, the enforcers of apoptosis, were increased by butyrate treatment. The results of Annexin V/PI staining and TUNEL also showed an increase in butyrate-induced apoptotic cells. Expression of Cytochrome C (Cytc), Caspase 9, Bax, but not Caspase 12 or 8, were up-regulated under butyrate exposure. Mechanistically, the decrease in mitochondrial NADH and NAD + levels after treatment with butyrate was observed by energy metabolomics and the NAD+/NADH Assay Kit, similar to the effects of the complex Ι inhibitor rotenone. Western blot results also demonstrated that the constituent proteins of mitochondrial complex Ι were reduced by butyrate. Furthermore, mitochondria-dependent apoptosis has been shown to be initiated by inhibition of the complex Ι. CONCLUSION Collectively, our results revealed that butyrate inhibited the proliferation, migration and invasion of CC cells, and induced mitochondrial-dependent apoptosis by inhibiting mitochondrial complex Ι.

Abstract
The vaginal microbiome has emerged as potentially influencing the natural history of Human Papillomavirus (HPV) infections and their clinical impact. We aimed to characterize the vaginal microbiome in samples from 807 high-risk HPVs (Hr-HPV) positive women with a mean age of 41.45 ± 10.79 years who participated in the Regional Cervical Cancer Screening Program from the Northern Region of Portugal. Microbiome analysis was performed with commercial kits for the detection of 21 microorganisms. The most frequent microorganisms were Ureaplasma parvum (52.5%), Gardnerella vaginalis (GV) (34.5%), Atopobium vaginae (AV) (32.6%), Lacto (30.7%), and Mycoplasma hominis (MH) (23.5%). The distribution according to age reveals that MH, Mega1, GV, BVab2, AV, and Mob were more prevalent in women older than 41 years of age (p < 0.050), while Lacto is significantly decreased in this group (23.5% vs. 39.4%, p < 0.001; RR = 0.47). The risk analysis showed that Hr-HPV-16/-18 and Hr-HPV-9val genotypes are associated with an increased risk of developing cervical abnormalities, while Lacto (p < 0.001; odd ratio [OR] = 0.33), GV (p = 0.0111; OR = 0.41), AV (p = 0.033; OR = 0.53) and Mob (p = 0.022; OR = 0.29) are associated with protection. Similar results were found for the risk of development atypical squamous cells cannot exclude HSIL/high-grade squamous intraepithelial lesion. Overall, the multivariate analysis confirmed that lactobacillus and bacteria associated with bacterial vaginosis (GV, AV, and Mob) are associated with protection against the development of cervical abnormalities. This study provides important data to be included in the future management of risk stratification for Hr-HPV-positive women.

The correlation between Trichomonas vaginalis infection and reproductive system cancer: a systematic review and meta-analysis. Infect Agent Cancer 2023; 18:15. [PMID: 36864428 PMCID: PMC9979407 DOI: 10.1186/s13027-023-00490-2] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2022] [Accepted: 02/14/2023] [Indexed: 03/04/2023] Open
Abstract
BACKGROUND Trichomonas vaginalis (T. vaginalis) is a microaerophilic protozoan parasite which is responsible for trichomoniasis, the most common non-viral sexually transmitted infection in the world. The infection greatly damages the reproductive system. However, whether T. vaginalis infection can cause reproductive system cancer remains controversial. METHODS This study systematically searched PubMed, EMBASE, Ovid and Google scholar, and 144 relevant articles were retrieved and classified into three categories: epidemiological investigations (68), reviews (30) and research articles (46). These three types of articles were verified according to their respective inclusion and exclusion criteria. Stata 16 was used to conduct a meta-analysis on the articles of epidemiological investigations for analysing the correlation between T. vaginalis infection and reproductive system cancer. RESULTS The result of meta-analysis indicated that the rate of T. vaginalis infection in the cancer group was significantly higher than that in the non-cancer group (OR = 1.87, 95% CI 1.29-2.71, I2 = 52%). Moreover, the cancer rate of the population infected with T. vaginalis was significantly higher than that of the population without T. vaginalis infection (OR = 2.77, 95% CI 2.37-3.25, I2 = 31%). The review articles and most research articles stated that the infection of T. vaginalis could lead to cancer and the pathogenic mechanisms were as follows: T. vaginalis promoting inflammatory response, T. vaginalis infection changing the internal environment around parasitic sites and signal transduction pathway, the metabolites secreted by T. vaginalis inducing carcinogenesis and T. vaginalis increasing other pathogenic microbial infection to promote the occurrence of cancer. CONCLUSIONS Our study confirmed that there was a correlation between the infection of T. vaginalis and reproductive system cancer, and provided some possible research directions for clarifying the carcinogenic mechanisms caused by T. vaginalis infection.

Abstract
This study aimed to explore the changes of the vaginal microbiota and enzymes in the women with high-risk human papillomavirus (HR-HPV) infection and cervical lesions. A total of 448 participants were carried out HPV genotyping, cytology tests, and microecology tests, and 28 participants were treated as sub-samples, in which vaginal samples were characterized by sequencing the bacterial 16S V4 ribosomal RNA (rRNA) gene region. The study found the prevalence of HR-HPV was higher in patients with BV (P = 0.036). The HR-HPV infection rate was 72.73% in G. vaginalis women, which was significantly higher than that of women with lactobacillus as the dominant microbiota (44.72%) (P = 0.04). The positive rate of sialidase (SNA) was higher in women with HR-HPV infection (P = 0.004) and women diagnosed with cervical intraepithelial neoplasia (CIN) (P = 0.041). In HPV (+) women, the α-diversity was significantly higher than that in HPV (-) women. The 16S rRNA gene-based amplicon sequencing results showed that Lactobacillus was the dominant bacteria in the normal vaginal microbiota. However, the proportion of Gardnerella and Prevotella were markedly increased in HPV (+) patients. Gardnerella and Prevotella are the most high-risk combination for the development of HPV (+) women. The SNA secreted by Gardnerella and Prevotella may play a significant role in HPV infection progress to cervical lesions.

Abstract
The human microbiome constitutes a complex multikingdom community that symbiotically interacts with the host across multiple body sites. Host-microbiome interactions impact multiple physiological processes and a variety of multifactorial disease conditions. In the past decade, microbiome communities have been suggested to influence the development, progression, metastasis formation, and treatment response of multiple cancer types. While causal evidence of microbial impacts on cancer biology is only beginning to be unraveled, enhanced molecular understanding of such cancer-modulating interactions and impacts on cancer treatment are considered of major scientific importance and clinical relevance. In this review, we describe the molecular pathogenic mechanisms shared throughout microbial niches that contribute to the initiation and progression of cancer. We highlight advances, limitations, challenges, and prospects in understanding how the microbiome may causally impact cancer and its treatment responsiveness, and how microorganisms or their secreted bioactive metabolites may be potentially harnessed and targeted as precision cancer therapeutics.

Abstract
Gynecological and obstetrical infectious diseases are an important component of women's health. A system approach to gynecological and obstetrical infection helps unify and classify microbial etiology and pathogenesis within a clinical anatomical framework of lower and upper genital tract syndromes. The reproductive system of women includes the vulva, vagina, cervix, uterus, fallopian tubes and ovaries. During pregnancy, additional tissues include the chorioamnion and placenta together with the fetus and amniotic fluid. We review in two parts reproductive system infection syndromes in women using selected research results to illustrate the clinical utility of the system approach in terms of diagnosis, treatment and prevention. We conclude that a reproductive system perspective will lead to improvements in understanding, management and prevention of these diseases.

Abstract
The microbiome, which refers to the microbiota within a host and their collective genomes, has recently been demonstrated to play a critical role in cancer progression, metastasis, and therapeutic response. The microbiome is known to affect host immunity, but its influence on human papilloma virus (HPV) gynecologic malignancies remains limited and poorly understood. To date, studies have largely focused on the cervicovaginal microbiome; however, there is growing evidence that the gut microbiome may interact and substantially affect therapeutic response in gynecologic cancers. Importantly, new developments in microbiome sequencing and advanced bioinformatics technologies have enabled rapid advances in our understanding of the gut and local tumor microbiota. In this review, we examine the evidence supporting the role of the microbiome in HPV-associated cervical intraepithelial neoplasia (CIN) and cervical cancer, explore characteristics that influence and shape the host microbiota that impact HPV-driven carcinogenesis, and highlight potential approaches and considerations for future and ongoing research of the microbiome's effect on HPV-associated cancer.

Abstract
Cancerous tumors are severe diseases affecting human health that have a complicated etiology and pathogenesis. Microbes have been considered to be related to the development and progression of numerous tumors through various pathogenic mechanisms in recent studies. Bacteria, which have so far remained the most studied microbes worldwide, have four major possible special pathogenic mechanisms (modulation of inflammation, immunity, DNA damage, and metabolism) that are related to carcinogenesis. This review aims to macroscopically summarize and verify the relationships between microbes and tumoral in situ tissues from cancers of four major different systems (urinary, respiratory, digestive, and reproductive); the abovementioned four microbial pathogenic mechanisms, as well as some synergistic pathogenic mechanisms, are also discussed. Once the etiologic role of microbes and their precise pathogenic mechanisms in carcinogenesis are known, the early prevention, diagnosis, and treatment of cancers would progress significantly.

Abstract
Persistent infection with some types of mucosal human papillomavirus (HPV) is the etiological factor for the development of cervical cancer and its precursor lesions. Besides, several cofactors are known to play a role in cervical disease onset and progression either by favoring or by preventing HPV infection and persistence. The microbiome of a healthy female genital tract is characterized by the presence of 1 or few varieties of lactobacilli. However, high-throughput studies addressing the bacterial diversity and abundance in the female genital tract have shown that several factors, including hormonal levels, hygiene habits, and sexually transmitted diseases may disrupt the natural balance, favoring the outgrowth of some groups of bacteria, which in turn may favor some pathological states. Recently, the vaginal microbiome has emerged as a new variable that could greatly influence the natural history of HPV infections and their clinical impact. In this context, changes in the vaginal microbiome have been detected in women infected with HPV and women with HPV-associated lesions and cancer. However, the role of specific bacteria groups in the development/progression or prevention/regression of HPV-associated pathologies is not well understood. In this review we summarize the current knowledge concerning changes in vaginal microbiome and cervical disease. We discuss the potential functional interplay between specific bacterial groups and HPV infection outcomes.

Abstract
BACKGROUND Vaginal dysbiosis characterized by depleted lactobacilli is usually correlated with human papillomavirus (HPV) infection and cervical carcinogenesis, but the effect of the Lactobacillus genus and represented species on this process remains unclear. METHODS PubMed, EMBASE, and CENTRAL databases were searched up to February 15, 2019. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using a fixed-effect model and Review Manager (version 5.3) for Mac. RESULTS Eleven studies comprising 1230 cases were included. Lactobacillus spp. was associated with the decreased detection of high-risk subtype (hr)HPV infection (OR = 0.64, 95% CI = 0.48-0.87, I2 = 6%), cervical intraepithelial neoplasia (CIN) (OR = 0.53, 95% CI = 0.34-0.83, I2 = 0%), and cervical cancer (CC) (OR = 0.12, 95% CI = 0.04-0.36, I2 = 0%). At the level of Lactobacillus species, Lactobacillus crispatus, but not Lactobacillus iners, was correlated with the decreased detection of hrHPV infection (OR = 0.49, 95% CI = 0.31-0.79, I2 = 10%) and CIN (OR = 0.50, 95% CI = 0.29-0.88, I2 = 0%). CONCLUSIONS Cervicovaginal Lactobacillus spp. is associated with the decreased detection of hrHPV infection, CIN, and CC; L. crispatus may be the critical protective factor.

Abstract
Despite ongoing efforts, sub-Saharan Africa faces a higher cervical cancer burden than anywhere else in the world. Besides HPV infection, definitive factors of cervical cancer are still unclear. Particular states of the cervicovaginal microbiota and viral infections are associated with increased cervical cancer risk. Notably, HIV infection, which is prevalent in sub-Saharan Africa, greatly increases risk of cervicovaginal dysbiosis and cervical cancer. To better understand and address cervical cancer in sub-Saharan Africa, a better knowledge of the regional cervicovaginal microbiome is required This review establishes current knowledge of HPV, HIV, cervicovaginal infections, and the cervicovaginal microbiota in sub-Saharan Africa. Because population statistics are not available for the region, estimates are derived from smaller cohort studies. Microbiota associated with cervical inflammation have been found to be especially prevalent in sub-Saharan Africa, and to associate with increased cervical cancer risk. In addition to high prevalence and diversity of HIV and HPV, intracellular bacterial infections such as Chlamydia, Gonorrhea, and Mycoplasma hominis are much more common than in regions with a low burden of cervical cancer. This suggests the prevalence of cervical cancer in sub-Saharan Africa may be partially attributed to increased cervical inflammation resulting from higher likelihood of cervical infection and/or microbial dysbiosis.

Abstract
Nearly all cervical cancers are causally associated with human papillomavirus (HPV). The burden of HPV-associated dysplasias in sub-Saharan Africa is influenced by HIV. To investigate the role of the bacterial microbiome in cervical dysplasia, cytobrush samples were collected directly from cervical lesions of 144 Tanzanian women. The V4 hypervariable region of the 16S rRNA gene was amplified and deep sequenced. Alpha diversity metrics (Chao1, PD whole tree, and operational taxonomic unit [OTU] estimates) displayed significantly higher bacterial richness in HIV-positive patients (P = 0.01) than in HIV-negative patients. In HIV-positive patients, there was higher bacterial richness in patients with high-grade squamous intraepithelial lesions (HSIL) (P = 0.13) than those without lesions. The most abundant OTUs associated with high-grade squamous intraepithelial lesions were Mycoplasmatales, Pseudomonadales, and Staphylococcus We suggest that a chronic mycoplasma infection of the cervix may contribute to HPV-dependent dysplasia by sustained inflammatory signals.IMPORTANCE HPV is known to be the causal agent in the majority of cervical cancers. However, the role of the cervical bacterial microbiome in cervical cancer is not clear. To investigate that possibility, we collected cervical cytobrush samples from 144 Tanzanian women and performed deep sequencing of bacterial 16S rRNA genes. We found that HIV-positive patients had greater bacterial richness (P = 0.01) than HIV-negative patients. We also observed that women with high-grade squamous intraepithelial lesions (HSIL) had greater cervical bacterial diversity than women with cytologically normal cervices. Data from our precise sampling of cervical lesions leads us to propose that Mycoplasma contributes to a cervical microbiome status that promotes HPV-related cervical lesions. These results suggest a greater influence of the bacterial microbiota on the outcome of HPV infection than previously thought.

Abstract
BACKGROUND Some studies demonstrated that female genital mycoplasmas play important roles in human papillomavirus (HPV) infection, abnormal cervical cytopathology, and cervical cancer. However, those results remained inconclusive. We aimed to perform a systematic review and meta-analysis to investigate the association between female genital mycoplasmas and those disorders. METHODS Computerized databases were comprehensively searched before 26 January 2017. Pooled odd radios (ORs) and correlative 95% confidence intervals (CIs) were adopted to evaluate the strength of association. RESULTS Our meta-analysis included 22 studies with 16,181 participants. Ureaplasma urealyticum and Ureaplasma parvum were associated with a significantly increased risk of overall HPV infection (OR 1.57, 95% CI 1.05-2.34; OR 3.02, 95% CI 2.10-4.33, respectively), and U. urealyticum and Mycoplasma genitalium were associated with a significantly increased risk of high-risk HPV infection (OR 1.37, 95% CI 1.05-1.80; OR 1.50, 95% CI 1.11-2.02, respectively). In addition, U. urealyticum, U. parvum, and Mycoplasma hominis were associated with a significantly increased risk of abnormal cervical cytopathology (OR 1.51, 95% CI 1.23-1.85; OR 1.41, 95% CI 1.10-1.80; OR 1.48, 95% CI 1.10-1.99, respectively). CONCLUSION We found that U. urealyticum and M. genitalium may increase the risk of high-risk HPV infection, while U. urealyticum, U. parvum, and M. hominis may increase the risk of abnormal cervical cytopathology.

Abstract
Background Some sexually transmitted infectious agents, such as Chlamydia trachomatis and Herpes simplex, cause local inflammation, and could contribute to Human Papillomavirus (HPV) and cervical lesion progression. Thus, the aim of this study was to determine any association between the presence of microorganisms of gynecological importance, sexual behavior, clinical and demographical variables to the development and progress of cervical lesions. Methods One hundred and thirty-two women between 14 and 78 years and living at Vitória da Conquista, Bahia, Brazil, were included (62 individuals with cervical lesions and 70 without lesions). They answered a questionnaire to provide data for a socioeconomic and sexual activity profile. Samples of cervical swabs were collected and analyzed by PCR to detect genital microorganisms and HPV. Quantitative PCR was used to detect and quantify Ureaplasma urealyticum and Ureaplasma parvum. Univariate and multiple logistic regression were performed to measure the association with the cervical lesions, and an odds ratio (OR) with 95% confidence intervals (95%CI) were calculated. The Mann-Whitney U test was also used to compare the microorganism load in the case and control groups. The significance level was 5% in all hypotheses tested. Results Cervical lesions were associated with: women in a stable sexual relationship (OR = 14.21, 95%CI = 3.67–55.018), positive PCR for HPV (OR = 16.81, 95%CI = 4.19–67.42), Trichomonas vaginalis (OR = 8.566, 95%CI = 2.04–35.94) and Gardnerella vaginalis (OR = 6.13, 95%CI = 1.53–24.61), adjusted by age and qPCR for U. parvum. U. parvum load showed a statistical difference between the case and control groups (p-value = 0.002). Conclusion Variables such as stable relationship, HPV, T. vaginalis, G. vaginalis were associated with cervical lesions in epidemiological studies. U. parvum load was higher in woman with cervical lesions compared with women without lesions. Additional studies are needed to better understand the role of these factors in cervical lesion development.

Abstract
BACKGROUND AND AIM Worldwide, 1,470,900 women are diagnosed yearly with a gynecological malignancy (21,000 in the UK). Some patients treated with pelvic radiotherapy develop chronic changes in their bowel function. This systematic review summarizes current research on the impact of cancer treatment on the gut and vaginal microbiome in women with a gynecological malignancy. METHODS The Preferred reporting Items for Systematic Reviews and Meta-analyses guidelines for systematic reviews were used to ensure transparent and complete reporting. Quantitative studies exploring the gut or vaginal microbiome in this patient cohort were included. Animal studies were excluded. There were no language restrictions. RESULTS No studies examined the possible effects of surgery or chemotherapy for gynecological cancers on the gut or vaginal microbiome.Three prospective cohort studies were identified using sequencing of changes in the gut microbiome reporting on a total of 23 women treated for gynecological cancer. All studies included patients treated with radiotherapy with a dosage ranging from 43.0 to 54.0 Gy. Two studies assessed gastrointestinal toxicity formally; 8 women (57%) developed grade 2 or 3 diarrhea during radiotherapy. The outcomes suggest a correlation between changes in the intestinal microbiome and receiving radiotherapy and showed a decrease in abundance and diversity of the intestinal bacterial species. Before radiotherapy, those who developed diarrhea had an increased abundance of Bacteroides, Dialister, and Veillonella (P < 0.01), and a decreased abundance of Clostridium XI and XVIII, Faecalibacterium, Oscillibacter, Parabacteroides, Prevotella, and unclassified bacteria (P < 0.05). CONCLUSION The limited evidence to date implies that larger studies including both the vaginal and gut microbiome in women treated for a gynecological malignancy are warranted to explore the impact of cancer treatments on the microbiome and its relation to developing long-term gastrointestinal toxicity. This may lead to new avenues to stratify those at risk and explore personalized treatment options and prevention of gastrointestinal consequences of cancer treatments.

Abstract
Cervical cancer (CC) is caused by high-risk human papillomavirus persistence due to the immunosuppressive tumor microenvironment mediated by cytokines. Vaginal microbiota determines the presence of certain cytokines locally. We assessed the association between cervical microbiota diversity and the histopathological diagnosis of each stage of CC, and we evaluated mRNA cervical expression levels of IL-4, IL-6, IL-10, TGF-β1, TNF-α and IFN-γ across the histopathological diagnosis and specific bacterial clusters. We determined the cervical microbiota by high throughput sequencing of 16S rDNA amplicons and classified it in community state types (CST). Mean difference analyses between alpha-diversity and histopathological diagnosis were carried out, as well as a β-diversity analysis within the histological diagnosis. Cervical cytokine mRNA expression was analyzed across the CSTs and the histopathological diagnoses. We found a significant difference in microbiota's diversity in NCL-HPV negative women vs those with squamous intraepithelial lesions (SIL) and CC(p = 0.006, p = 0.036).When β-diversity was evaluated, the CC samples showed the highest variation within groups (p<0.0006) and the largest distance compared to NCL-HPV negative ones (p<0.00001). The predominant bacteria in women with normal cytology were L. crispatus and L. iners, whereas for SIL, it was Sneathia spp. and for CC, Fusobacterium spp. We found higher median cervical levels of IL-4 and TGF-β1 mRNA in the CST dominated by Fusobacterium spp. These results suggest that the cervical microbiota may be implicated in cervical cancer pathology. Further cohort studies are needed to validate these findings.

Abstract
Naturally occurring cancers in non-laboratory species have great potential in helping to decipher the often complex causes of neoplasia. Wild animal models could add substantially to our understanding of carcinogenesis, particularly of genetic and environmental interactions, but they are currently underutilized. Studying neoplasia in wild animals is difficult and especially challenging in marine mammals owing to their inaccessibility, lack of exposure history, and ethical, logistical and legal limits on experimentation. Despite this, California sea lions (Zalophus californianus) offer an opportunity to investigate risk factors for neoplasia development that have implications for terrestrial mammals and humans who share much of their environment and diet. A relatively accessible California sea lion population on the west coast of the USA has a high prevalence of urogenital carcinoma and is regularly sampled during veterinary care in wildlife rehabilitation centres. Collaborative studies have revealed that genotype, persistent organic pollutants and a herpesvirus are all associated with this cancer. This paper reviews research to date on the epidemiology and pathogenesis of urogenital carcinoma in this species, and presents the California sea lion as an important and currently underexploited wild animal model of carcinogenesis.

Abstract
BACKGROUND Human papillomavirus (HPV) infections in Thailand are a public health concern, but information on HPV infection in sex workers and men who have sex with men (MSM) is limited. The aim of this study was to measure the prevalence and genotype distribution of HPV among low- and high-risk, HIV-negative populations. METHODS A total of 300 participants were categorized as general women, female sex workers, MSM, and MSM sex workers. Human papillomavirus infections were identified by the Papanicolaou test and nested polymerase chain reaction. A phylogenetic analysis of partial HPV L1 genes was performed. RESULTS Abnormal cytology was found in 5% of general women, 10% of female sex workers, 24% of MSM, and 28% of MSM sex workers. Human papillomavirus was detected in 9% of general women, 13% of female sex workers, and 30% in both MSM and the MSM sex workers. The prevalence of HPV high-risk genotypes was significantly higher in female sex workers and MSM, whereas low-risk genotypes and genital warts were significantly higher in MSM sex workers. Significantly more patients with genital warts and cervical intraepithelial neoplasia I/anal intraepithelial neoplasia I harbored low-risk genotypes, whereas those with cervical intraepithelial neoplasia II/anal intraepithelial neoplasia II harbored high-risk genotypes. CONCLUSIONS High- and low-risk HPV genotypes persist in high-risk groups in Bangkok. Some genotypes infecting at-risk populations are not vaccine preventable. These findings may help to elucidate the prevalence of HPV infections in Thailand and serve as the basis for additional investigations into risk factors for these populations.

Abstract
Humans have evolved along with the millions of microorganisms that populate their bodies. These microbes (10(14)) outnumber human cells by 10 to 1 and account for 3 × 10(6) genes, more than ten times the 25,000 human genes. This microbial metagenome acts as our "other genome" and like our own genes, is unique to the individual. Recent international efforts such as the Human Microbiome Project (HMP) and the MetaHIT Project have helped catalog these microbial genomes using culture-independent, high-throughput, next-generation sequencing. This manuscript will describe recent efforts to define microbial diversity in the female reproductive tract because of the impact that microbial function has on reproductive efficiency. In this review, we will discuss current evidence that microbial communities are critical for maintaining reproductive health and how perturbations of microbial community structures can impact reproductive health from the aspect of infection, reproductive cyclicity, pregnancy, and disease states. Investigations of the human microbiome are propelling interventional strategies from treating medical populations to treating individual patients. In particular, we highlight how understanding and defining microbial community structures in different disease and physiological states have lead to the discovery of biomarkers and, more importantly, the development and implementation of microbial intervention strategies (probiotics) into modern day medicine. Finally this review will conclude with a literature summary of the effectiveness of microbial intervention strategies that have been implemented in animal and human models of disease and the potential for integrating these microbial intervention strategies into standard clinical practice.

Abstract
Background: Trichomonas vaginalis, Gardrenella vaginalis, and Candida sp are responsible for 90% of vaginitis which has been reported as important risk factors for cervical cancer. Aim: This study aimed to find the prevalence of T. vaginalis, Candida sp, and G. vaginalis in women attended the cancer clinic charity, Babol, Iran and to identify the associated risk factors. Materials and Methods: This retrospective study carried out from 1996 to July 2012 on women who attended to a cancer screening program at the cancer clinics charity, Babol, Iran. Papanicolaou test and clinical examinations were performed for each woman. In addition to Papanicolaou test results, demographic data were collected. The data were analyzed with X2 test using SPSS software, version 18. Results: In total, 2511 out of 33600 (7.5%) cases had vaginal infections. A total of 71 (0.2%), 2248 (6.7%), and 192 (0.6%) of subjects were infected by T. vaginalis, Candida sp, and Gardnerella, respectively. The highest rate of infection was seen in 20-30 and 30-40 years age group. The frequency of vaginal ulcers was higher in trichomoniasis (14.1%). Conclusion: This study demonstrated that the prevalence of T. vaginalis, Candida sp, and Gardnerella was low among the studied population. Moreover, malignant cytological alternations were not seen in any infected women.

Abstract
This is to investigate the cervical cytological abnormalities associated with Chlamydia trachomatis, Mycoplasma hominis, Mycoplasma genitalium, and Ureaplasma urealyticum infections on routine screen. A total of 714 subjects who had undergone cervical Pap smears and concomitant analyses for cervical infections were included by a retrospective search. The frequencies of reactive cellular change (RCC) and squamous epithelial abnormalities were significantly higher in Chlamydia positive subjects than in uninfected subjects (P<0.001). Of the 124 subjects tested for M. hominis, M. genitalium, and U. urealyticum, 14 (11%) were positive for M. hominis and 29 (23%) were positive for U. urealyticum. Squamous abnormalities were more frequent in subjects with Ureaplasma infections than in uninfected subjects (24% versus 8%). Taking together these findings, C. trachomatis and U. urealyticum may have a causal role in the development of cervical epithelial changes, including RCC. Thus, extra awareness is warranted in cervical screening of women with Chlamydia or Ureaplasma infections.

Abstract
OBJECTIVE Bacterial vaginosis (BV), the most common vaginal disorder among women of reproductive age, has been suggested as co-factor in the development of cervical cancer. Previous studies examining the relationship between BV and cervical intra-epithelial neoplasia (CIN) provided inconsistent and conflicting results. The aim of this study is to clarify the association between these two conditions. METHODS A systematic review and meta-analysis were conducted to summarize published literature on the association between BV and cervical pre-cancerous lesions. An extensive search of electronic databases Medline (Pubmed) and Web of Science was performed. The key words 'bacterial vaginosis' and 'bacterial infections and vaginitis' were used in combination with 'cervical intraepithelial neoplasia', 'squamous intraepithelial lesions', 'cervical lesions', 'cervical dysplasia', and 'cervical screening'. Eligible studies required a clear description of diagnostic methods used for detecting both BV and cervical pre-cancerous lesions. Publications were included if they either reported odds ratios (OR) and corresponding 95% confidence intervals (CI) representing the magnitude of association between these two conditions, or presented data that allowed calculation of the OR. RESULTS Out of 329 articles, 17 cross-sectional and 2 incidence studies were selected. In addition, two studies conducted in The Netherlands, using the national KOPAC system, were retained. After testing for heterogeneity and publication bias, meta-analysis and meta-regression were performed, using a random effects model. Although heterogeneity among studies was high (χ(2) = 164.7, p<0.01, I(2) = 88.5), a positive association between BV and cervical pre-cancerous lesions was found, with an overall estimated odds ratio of 1.51 (95% CI, 1.24-1.83). Meta-regression analysis could not detect a significant difference between studies based on BV diagnosis, CIN diagnosis or study population. CONCLUSIONS Although most studies were cross-sectional and heterogeneity was high, this meta-analysis confirms a connection between BV and CIN.

Abstract
INTRODUCTION HIV-positive women have an increased risk of invasive cervical cancer but cytologic screening is effective in reducing incidence. Little is known about cervical screening coverage or the prevalence of abnormal cytology among HIV-positive women in Ukraine, which has the most severe HIV epidemic in Europe. METHODS Poisson regression models were fitted to data from 1120 women enrolled at three sites of the Ukraine Cohort Study of HIV-infected Childbearing Women to investigate factors associated with receiving cervical screening as part of HIV care. All women had been diagnosed as HIV-positive before or during their most recent pregnancy. Prevalence of cervical abnormalities (high/low grade squamous intraepithelial lesions) among women who had been screened was estimated, and associated factors explored. RESULTS Overall, 30% (337/1120) of women had received a cervical screening test as part of HIV care at study enrolment (median 10 months postpartum), a third (115/334) of whom had been tested >12 months previously. In adjusted analyses, women diagnosed as HIV-positive during (vs before) their most recent pregnancy were significantly less likely to have a screening test reported, on adjusting for other potential risk factors (adjusted prevalence ratio (APR) 0.62, 95% CI 0.51-0.75 p<0.01 for 1(st)/2(nd) trimester diagnosis and APR 0.42, 95% CI 0.28-0.63 p<0.01 for 3(rd) trimester/intrapartum diagnosis). Among those with a cervical screening result reported at any time (including follow-up), 21% (68/325) had a finding of cervical abnormality. In adjusted analyses, Herpes simplex virus 2 seropositivity and a recent diagnosis of bacterial vaginosis were associated with an increased risk of abnormal cervical cytology (APR 1.83 95% CI 1.07-3.11 and APR 3.49 95% CI 2.11-5.76 respectively). CONCLUSIONS In this high risk population, cervical screening coverage as part of HIV care was low and could be improved by an organised cervical screening programme for HIV-positive women. Bacterial vaginosis testing and treatment may reduce vulnerability to cervical abnormalities.

Abstract
The Dutch cytological coding system, KOPAC, enables to code for eight inflammatory events, that is koilocytosis (related to human papillomavirus (HPV)), Trichomonas, dysbacteriosis [related to bacterial vaginosis (BV)], Candida, Gardnerella, Actinomyces, Chlamydia, and non-specific inflammation (leucocytosis). This study presents an analysis of 1,008,879 smears. Of each smear, the age of the woman and the reason for smear taking (screening or indication) was available. The cytoscores (per mille) for these codes were calculated. For the screening smears, the cytoscores were for koilocytosis (HPV) 2.6, for Trichomonas vaginalis 1.9, for dysbacteriosis 31.4, for Candida albicans 9.8, for Gardnerella vaginalis 0.7, for Actinomyces 6.9, for Chlamydia 0.8, and for non-specific inflammatory changes 66.4. For the calculation of the Odds Ratio (OR), normal smears were used as a reference. The cytoscores for Chlamydia and Gardnerella covaried with high grade SIL (HSIL), with an OR of 7 and 12, respectively. In addition, the OR for Trichomonas vaginalis, for dysbacteriosis, and for leucocytosis proved to be significantly high in the indication smears. This study provides an oversight of HSIL and the full range of cervical infections as detected by cytology, proving that this infectious byproduct of screening can be very valuable.

Abstract
The relation between the detection of clue cells in cervical smears of women with CIN and the expression of COX-2 in these lesions were determined. Samples from 228 women, treated due to CIN and who underwent cervical conization, were obtained. Hybrid Capture II and Pap smear samples were collected immediately before performing conization. Pathological diagnoses were 11 (5%) normal cervix, 35 (15%) CIN1, 31 (14%) CIN2, and 151 (66%) CIN3. COX-2 immunoreactivity grading on the pathological specimens was based on the German ImmunoReactive score. In cervical smears, 20 fields (40x) were examined, each of them with a minimum count of 10 epithelial cells. When 20% or more of clue cells were detected the sample was considered positive for clue cells. The prevalence of clue cells was similar across histological strata (P = 0.42). Although the expression of COX-2 did not differ in lesions with varying severities (P = 0.24), there was a negative association between the expression of COX-2 and the presence of clue cells in Pap smear (OR = 0.4; 95% CI = 0.2-0.9): only 12% of women with moderate and strong expression of COX-2 had clue cells in their smears, contrasted to 22% of those with negative and weak expression of COX-2. HPV infection was associated in a borderline manner to the expression of COX-2 (P = 0.04; OR = 2.3 95% CI = 1.0-5.4). The reduced expression of COX-2 in CIN specimens may suggest that clue cells interfere with the inflammatory component of the carcinogenic process that lead to CIN.

Abstract
OBJECTIVE The aim of the present study was to evaluate the expression of pan-cadherin and beta-catenin in cervical smears with various types of infectious agents. PATIENTS AND METHODS Cervical smears obtained from 53 women, aged 21-65 years, with a diagnosis of specific inflammation were examined in our study. Eighteen subjects were infected by Candida albicans, 18 by Gardnerella vaginalis, nine by Bacteroides spp. and eight by Chlamydia trachomatis. All infectious agents found in the smears were at the same time confirmed by the microbiological laboratory methods. We performed a biotin-streptavidin-peroxidase immunocytochemical method using anti-beta-catenin (Clone 12F7) and anti-pan-cadherin (pan, polyclonal) antibodies. RESULTS Aberrant expression of pan-cadherin was found in the cytoplasmic membrane of glandular, metaplastic, superficial and intermediate squamous cells in all types of infections. With regard to beta-catenin, this was expressed in majority (90%) of glandular and metaplastic cells in all types of infections and in a small proportion (15%) of superficial and intermediate squamous cells in infections caused by C. albicans and G. vaginalis. CONCLUSION Our data show that infectious agents may cause alterations in the expression and distribution of these adhesive molecules, which can be recognized in cervical smears. Additional studies in larger sets of patients should help clarify this issue further.

Abstract
The objective of this study was to establish the relationship between Candida vaginalis and (pre)neoplasia and the prevalence of Candida and (pre)neoplasia related to age and ethnicity. Data were collected from 445,671 asymptomatic women invited for mass screening between 1995 and 2002 and coded according to the Dutch cervical smear coding system (KOPAC) with six grades for (pre)neoplastic changes. Prevalence and relative risks (RRs) were established for Candida and squamous abnormalities in Dutch women and four groups of immigrants. The prevalence of Candida is significantly higher in the cohort of 30-year-old women and lower in the cohorts of 45-, 50-, 55-, and 60-year-old women. The RR of having Candida was higher for Surinamese women (1.24; CI 1.08-1.42). Furthermore, the RR of having mild dysplasia was higher for Surinamese women (1.47; CI 1.14-1.89) and for women born in other countries than in The Netherlands, Turkey, and Morocco (1.36; CI 1.13-1.62). No statistically significant relationship between (pre)neoplasia and Candida was observed. C. vaginalis is more frequent among Surinamese women. Presence of Candida is not associated with an increased risk for squamous abnormalities; therefore, women carrying Candida are not at an increased risk of developing cervical cancer.

Abstract
OBJECTIVE To identify alterations in the cytokine profile and microbial ecosystem of the vagina in association with cervical dysplasia. METHODS Demographics, lifestyle variables and Papanicolau (Pap) smear results of subjects presenting to the same site for gynecologic complaints, obstetric visits or colposcopy were prospectively recorded. Vaginal smear for Gram stain, aerobic and anaerobic culture, pH, and wet mount and KOH examination for Trichomonas vaginalis, Gardnerella vaginalis and yeast organisms were performed. Vaginal lavage specimens were centrifuged, and the pellets and supernatants were assayed for human papillomavirus (HPV) by polymerase chain reaction and for cytokines interleukin (IL)-1beta IL-6, IL-10 and IL-12 by enzyme-linked immunosorbent assay (ELISA) respectively. Subjects with abnormal Pap smears underwent colposcopy and biopsy as indicated. RESULTS Of 51 patients, 32 were referred for colposcopy, 12 presented with gynecologic needs, and seven presented for obstetric visits. Median age was 24 years. Demographics did not differ significantly between the dysplasia and control groups except for a trend towards more sexual partners in the dysplasia group. Biopsies were performed in 81% (26/32) of patients presenting for colposcopy and 17 revealed cervical intraepithelial neoplasia. IL-1beta, IL-6, IL-10, and IL-12 levels were elevated in 63% (20/32), 38% (15/39), 4% (2/49), and 0% of samples respectively. Elevated vaginal lavage IL-1beta was associated with a 6.1 odds ratio (95% confidence interval 1.06-35) of cervical dysplasia. Alterations in other variables studied were not associated with cervical dysplasia. CONCLUSIONS Elevated IL-1beta, possibly representing a complex host inflammatory response to multiple pathogens, was demonstrated in patients with cervical dysplasia.

Abstract
Cervical cancer patients may experience hip problems related to the cancer itself or therapeutic management for the cancer. Septic arthritis should be one of the possibilities but there have been no reports on this. Here we present three patients who developed hip problems more than two years after radiotherapy with or without a radical operation. One patient was managed as septic arthritis because of significant inflammatory signs around the affected hip joint even though the causative organism was not confirmed. Succeeding total hip arthroplasty functioned well and had no recurrence of infection. The hip problems of the other two patients were diagnosed as radiation osteonecrosis of the femoral head initially. However, Bacteroides fragilis infection was found several months after total hip arthroplasties. Radiotherapy to the pelvis may damage the hip joint and compromise host-defense mechanisms of the pelvic region. Both factors may increase the possibility of infection of hip joints. Further clinical evidence is needed to understand whether subacute or chronic anaerobic infection could also be one of the causes leading to progressive destruction of the femoral head.

Abstract
A longitudinal cohort study was carried out to determine whether gynaecological infections other than human papillomavirus (HPV) are also related to the subsequent increased risk of cervical neoplasia. The study comprised 19114 women attending the organized mass screening in Finland in 1985-1990 with cytologically detected HPV, Actinomyces, herpes simplex, Trichomonas vaginalis, or yeast. The women were followed-up for subsequent preinvasive lesions and invasive cancers until the end of 1994 by linkage to the nation-wide Cancer Registry. Standardized incidence ratios (SIR) with rates for the whole of Finland as reference and 95% confidence intervals (CI) were estimated. Trichomonas vaginalis and HPV were associated with a high relative risk of cervical cancer, SIR 6.4 (CI 3.7-10, preinvasive lesion and invasive cancer combined) and SIR 5.5 (CI 4.2 7.2, preinvasive lesion and invasive cancer combined), respectively. Herpes simplex was rarely detected, but the highest and statistically most significant point estimate was observed (SIR 12, CI 2.4-34, preinvasive lesion and invasive cancer combined). Neither Actinomyces nor yeast was associated with a significantly increased risk of cervical cancer. None of these results could be accounted for by the confounding effect of the other infections. Our results, based on a prospective design, lead us to propose that Trichomonas vaginalis and herpes simplex virus are also predictors for cervical neoplasia.

Abstract
The impact of sexually transmitted diseases (STDs) on the development of cervical intraepithelial neoplasia (CIN) has been increasingly recognized over the last 20 years. Much attention has been focused on human papillomavirus (HPV) and the potential for screening for certain HPV types alongside standard cervical cytology in the hope of identifying those females at particular risk of developing high grade CIN or invasive carcinoma. Some infections, for example herpes simplex virus (HSV), have been heavily investigated in the past as they were thought to be involved in the development of CIN but were subsequently discounted. Also discounted as causes of CIN are Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT). These infections were found to be associated with higher rates of CIN in early studies but transpired to be markers for the presence of other infections and pathology and therefore not themselves directly responsible for cytological changes. The role of bacterial vaginosis (BV) is the focus of several current investigations, not only in the genesis of CIN but also in the development of other gynecological and obstetric conditions and complications. Evidence to implicate Trichomonas vaginalis (TV) in the genesis of CIN is conflicting, but there is some evidence that it may exert its influence in a similar way to that hypothesized for BV, ie via abnormal amines. It is well known that there is a high level of concordance of STDs whereby the presence of one infection greatly increases the likelihood of there being one or more others present. There may be a synergism between some infections with regard to the causation of CIN, although the evidence for this is putative. Presented here is an overview of current and previous research in the field of lower genital tract infection as it relates to the development of CIN.

Abstract
BACKGROUND The purpose of this study was to examine, prospectively, the presence and extent of cervical epithelial immaturity as well as the rate of squamous metaplastic activity as a risk for the development of low grade squamous intraepithelial lesions (LSIL). METHODS The study was a nested case-control design that used subjects from an ongoing cohort study of human papillomavirus infection. Fifty-four sexually active young women who developed LSIL were matched for age and number of visits with 54 women who had never developed LSIL. The percent of cervical immaturity was interpreted from colpophotography using a computer-generated pixel count of delineated immature and total cervical areas. Activity of squamous metaplasia was interpreted as the percent change in the area of immaturity over a defined time period. Conditional logistic regression analysis examined risks for the development of LSIL. RESULTS Baseline area of biologic immaturity was not a predictor of LSIL. However, women with the a high degree of metaplastic activity near the SIL event were more likely to develop LSIL (odds ratio = 3.01 [95% confidence interval, 1.3, 6.8] for every 10% unit change in area of immaturity). CONCLUSIONS A rapid rate of metaplastic change within the transformation zone, rather than the initial area of biologic immaturity, is a significant risk factor for the development of LSIL.

Abstract
Since other viruses can influence expression of human papillomavirus (HPV) 16 E6-E7 genes in vitro, this study addressed whether specific vaginal bacteria do so as well. The vaginal microflora of 18 women with cervical intraepithelial neoplasia (CIN) or normal histology and HPV 16 infection, was evaluated by quantitative culture. Expression of HPV 16 E6-E7 oncogenes was assessed in exfoliated cervical cells by quantitative polymerase chain reaction. HPV 16 expression was also quantitated in CaSki carcinoma cell line cocultured with Bacteroides fragilis or Lactobacillus acidophilus. Isolation of Lactobacillus sp. (p = 0.05) and expression of the E6*II transcript (p = 0.03) were associated with low-grade CIN or normal histology. However, changes in E6-E7 expression were not associated independently with isolation of a specific microorganism. Similarly, expression of HPV 16 E6-E7 oncogenes in vitro was unaltered in the presence of bacteria. These results suggest that vaginal microorganisms are unlikely to alter the natural history of HPV-associated CIN by influencing HPV oncogene expression.

Abstract
Clinically, it is important to detect mycoplasmas because these organisms have been implicated in gastric and ovarian cancer, pneumonia, postabortal fever, pelvic inflammatory disease, pyelonephritis, endometritis, urethritis, perinatal mortality, arthritis, spontaneous abortion, infertility and interference with sperm development and they act as cofactors catalyzing the HIV disease state. Recently, the combined polymerase chain reaction and enzyme-linked immunosorbent assay method targeting the consensus DNA of over 15 species of mycoplasmas was shown to be superior for the detection of mycoplasmas. The objective was to determine if there was an association between mycoplasmas and cervical neoplasia. Cervical tissues, histopathologically categorized by cervical intraepithelial neoplasia (CIN) grade, flat or exophytic, and acanthosis or koilocytotic, were used. The results showed that mycoplasmas DNA were present in 21.4% of the condyloma tissues and in 33.3% of condyloma tissues with CIN. In contrast, mycoplasmas DNA were not detected when there were no CIN. The presence or absence of human papillomavirus (HPV) did not make a difference. Mycoplasmas DNA were present in 40.0 and 12.5% of the exophytic and flat condylomas, respectively. A higher percentage of cervical tissues graded with slight koilocytosis had (P = 0.05) mycoplasmas DNA compared with tissues graded with moderate koilocytosis. The detection of mycoplasmas DNA in archived cervical condyloma tissues with CIN corroborated previous reports of an association between mycoplasmas and CIN. However, the association between mycoplasmas and the presence of HPV could not be made in this study.

Abstract
The aim of this study was to correlate the significance of vaginal microbiology, in particular its anaerobic component, to the presence of bacterial vaginosis (BV), and to review the clinical criteria used in the diagnosis of this condition. Ninety-two female patients who received routine STD screening were studied. After routine history, presence and character of vaginal discharge and vaginal pH were noted, an amine test performed, and a wet stain observed microscopically. Routine Gram stain smears and cultures were prepared. BV was diagnosed clinically in 28 (30%) of our sample, and Gardnerella vaginalis was cultured in 41 patients (45%). Both clue cells and anaerobes were closely associated with each other and both mutually exclusive with the presence of lactobacilli on Gram stain (P < 0.001). BV was found to be strongly associated with the presence of clue cells on the wet film, anaerobes and G. vaginalis. In conclusion, bacterial vaginosis is not only strongly associated with the presence of G. vaginalis in the vaginal flora, but more strongly with the presence of anaerobes. The study suggests that the microaerophile G. vaginalis is a commensal organism in a significant proportion of sexually active women. If the aerobic status of the healthy vagina is disrupted, anaerobes (including Gardnerella) will flourish, producing the clinical picture of bacterial vaginosis.
