ABSTRACT

Cervical cancer is a reproductive health problem in women, ranking third among cancers, remains the leading cause of cancer death among women in developing countries. Vaginal infection by microorganisms is commonly found in the adolescent period and reproductive age.
Objective. To study the prevalence of Streptococcus agalactiae in women with cervical dysplasia.
Methods. The study included 200 patients with cervical dysplasia, aged 17 to 80 years old. Vaginal culture was performed, and in the case of vaginal swab samples were taken three, placing them in sterile saline solution, Stuart transport and Streptocel media for processing in the laboratory. The tube with saline solution used to make a fresh examination, Stuart medium was inoculated into enrichment, selective and differential media for the identification of microorganisms that were isolated. Once the broth Streptocel was incubated for 24 hours at 37° C, were inoculated on ram blood agar plate which was incubated at 37° C for 24 hours.
Results. The prevalence of cervical dysplasia was higher in the age group 33 to 40 years 32.4%. Of the 200 vaginal swabs in 83 (41.5%) had isolated some microorganisms of medical importance of these in 60 (30%) identified the presence of a single organism, and in 23 (11.5%) cases were isolated more of an etiologic agent. Streptococcus agalactiae was isolated in 5.5% of the cases studied.
Conclusion. The frequency of S. agalactiae is similar to the general population in Mexico.
