ABSTRACT

Introduction. Cervicovaginits is one of the 12 main reasons of consultation in family medicine units of IMSS, and is among the 20 most common diagnoses in first level of health care. It represents 38% of the consultations in women from 20 to 59 years of age. The most common etiologic agents are Gardnerella vaginalis, Candida spp., Candida albicans and Trichomonas.
Material and methods. This is a transversal, descriptive, retrospective study. Files belonging to women who had vaginal cultures from January to June 2014 were checked. Information was obtained from the FMU 171 laboratory, of the Instituto Mexicano del Seguro Social (IMSS). We calculated the sample size using EPI INFO. The sample included 74 files and statistical analysis was done using SPSS. Frequencies and proportions were used in qualitative variables. For quantitative values we used median, mode and standard deviation.
Results. 35% of women were among 26 to 35 years old. 96% of cultures yielded a positive result, the infectious agents found were Gardnerella vaginalis 16.2%, Escherichia coli 14.9%, Group B streptococci 14.9%, Candida albicans 13.5%, Candida spp 12.2%, Prevotella spp 8.1%, Trichomonas vaginalis and D streptococci 5.4%, Neisseria gonorrhoeae 2.7%, Chlamydia trachomatis and Mobiluncus spp 1.4%. The test was negative in 4% of the cases.
Discussion. Bacteria turned out to be the most frequent isolated agent in cultures from patients in FMU 171, the most common bacterial agent was Gardnerella vaginalis (16.2%). Cervicovaginitis is most common in women of reproductive age, prevalence is higher in those between 26-35 years old. It is very important to perform a vaginal culture in order to confirm the presence of the agent. Adequate treatment must be started in order to avoid consequences related to infection.
