Abstract:	INTRODUCTION. The culture of vaginal secretions and different methods for molecular identification of microorganisms are considered as reference in the diagnosis of infections. However, many infections of the lower genital tract are detected by cervical cytology, which the routinely diagnostic method is used to prevention of cervical cancer. OBJECTIVE. Evaluate the abnormal bacterial microbiota frequency in cervical secretion by cytology and culture; evaluate the agreement between these diagnostic methods and the association between abnormal bacterial microbiota with inflammation and clinical aspects. METHOD. This study was done in 55 patients treated at Gynecology Service in the University Hospital of Brasilia (HUB) in the years 2015 and 2016. They were subjected to clinical examination and collection of cervical secretion for cytology and culture. The identification of bacteria was performed by automated method (Vitek 2 - Biomeriéux). RESULTS. The pathogenic bacteria grew up in 45.45% of cervical samples submitted to culture / VITEK. Between eight isolated species, the most common were Streptococcus agalactiae and Enterococcus faecalis (20% and 12.72% of the total samples, respectively). In cervical cytology, abnormal bacterial microbiota was observed in 52.72% of the samples and inflammation in 78.18% of the samples. The agreement between abnormal bacterial microbiota in cytology and growth of pathogenic bacteria in culture / VITEK was 60% (kappa = 0.2). The inflammation was significantly more frequent in samples with abnormal bacterial microbiota compared with normal samples bacterial microbiota in cervical cytology (Fisher's exact test, p = 0.03). Although the inflammation findings in cytology ere more frequent in samples from patients with growth of pathogenic bacteria compared to samples with no growth of bacteria in the cervical secretion culture, the difference was not significant. Regarding demographics aspects, medical history, sexual activity and lifestyle habits, only the age (mean) of patients it was significant between the groups with and without growth of pathogenic bacteria in the cervical secretion culture. CONCLUSION. Abnormal bacterial microbiota was a frequent finding in cervical cytology and the agreement rate between the presence of abnormal bacterial microbiota in cervical cytology and growth of pathogenic bacteria in cervical secretion culture was poor. The findings of inflammation in cervical cytology was common in the samples with abnormal bacterial microbiota and their presence in samples with normal microbiota suggests causes of non- infectious origin but causes of infectious origin cannot be excluded. In contrast, the presence of abnormal bacterial flora without inflammation in the cervical cytology samples suggests that these bacteria are not necessarily pathogenic. The low frequency of signs and symptoms and the limited number of samples of this study did not allow a reliable analysis of the association between growth of pathogenic bacteria in the cervical secretion culture and its possible clinical consequences.
