Résumé
"Objective. To estimate the prevalence and analyze thefactors associated with group B Streptococcus (GBS) colonizationin pregnant women of Los Altos, Chiapas, Mexico.Material and methods. Between February and September1999, a cross-sectional study was conducted among 910women who sought delivery care at three public hospitalsof San Cristobal de Las Casas, Chiapas. Vaginal and perianalsamples were taken for GBS detection by bacteriologicalculture. Identification of groups and serotypes was performedusing latex agglutination. The analysis of factorsassociated with colonization was done using chi-squaredtests and log-linear modeling. Results. GBS colonizationwas found in 8.6% (95% CI 6.8 - 10.5) of study subjects.Women with the greatest likelihood of colonization werethose with ³5 pregnancies, residents of counties with highlevels of poverty, working outside the home, and living inhomes in which the head of household worked in agriculture(26.8%, OR= 7.25, 95% CI 1.83 - 28.67). Conclusions. Inthe study area, it is necessary that actions aiming to preventand control infections by GBS be directed principally at thosegroups of women with the highest probability of colonization,in order to diminish the perinatal transmission of GBS."
