DIAZ DE R., T.; NIEVES, B.  y  VEGAS, L.. Rectovaginal colonization by group B Streptococcus in pregnant women with gyno-obstetrics complications.. Rev. Soc. Ven. Microbiol. [online]. 2002, vol.22, n.1, pp.12-17. ISSN 1315-2556.

The present work is an attempt to determine the clinical and epidemiological factors and the frequency of colonization by group B Streptococci (GBS) in pregnant women with gynecological and obstetric complications attended by the Emergency Obstetrics Service of the Instituto Autónomo Hospital Universitario de Los Andes (IAHULA) from April to October 2000. 60 women with gynecological and obstetric problems were included in the study and rectovaginal and endocervical swabs taken, were incubated in Columbia blood agar with nalidixic acid (15µg/ml) and gentamicin (8µg/ml). Standard tests gave an approximate identification, while definitive identification was based on the presence of GBS cell wall antigen (Slidex- Strepto B-BioMérieux). In the study period, GBS was isolated with a high degree of frequency (36.7%) in rectovaginal cultures from pregnant women with gynecological and obstetric complications. Nor was there any significant correlation between GBS colonization and the clinical and epidemiological features of the women in the study, although GBS was recovered with greater frequency from pregnant women with an average age of 25.5, low level of education, living with a partner, non-smoker and in the 35 - 36 week of pregnancy.
