Background: Establish the prevalence of microorganisms associated with genital colonization in symptomatic pregnant women. In order to review the evolution of frequent pathogens ecology and adjust the laboratory design, in a population attended at the public health Hospital, in the Great Buenos Aires.
Methods: Vaginal and endocervical samples, were explored for specific detection of Chlamydia trachomatis, Neisseria gonorrhoeae, Streptococcus agalactie, Trichomonas vaginalis, Candida spp., Mycoplasma hominis, Ureaplasma urealyticum and bacterial vaginosis (VB).Direct methods, culture, inmunodetection and PCR, were employed. In 1999; 198 women, with genital discharge, were studied. Age in the group range from 16 to 42 years old (Median 27 years old).
Results: In 51 cases (25.7%) none of the above microorganisms or bacterial vaginosis were detected. In 30 cases (15.1%) bacterial vaginosis was diagnosed. Frequency of detection was: Ureaplasma urealyticum, 49,5%; Candida spp., 34,3%; Mycoplasma hominis, 14.1%; Streptococcus agalactie, 4.5%; Trichomonas vaginalis, 3.5%; Chlamydia trachomatis, 2.5%. No detection of Neisseria gonorrhoeae was demonstrated.
Conclusions: There is a relevant frequency of bacterial vaginosis. On the other hand, lower prevalence of the Trichomonas vaginalis and Chlamydia trachomatis and also the absence of Neisseria gonorrhoeae was demonstrated. Culture for Streptococcus agalactie (at birth) and detection of Chlamydia trachomatis. must be extended to all pregnant women. Study of species and drug sensitivity of Candida spp., and detection of Ureaplasma urealyticum, Mycoplasma hominis and Neisseria gonorrhoeae, have to be explored under specific clinical requirement.
