Colonization with group B streptococci (GBS) in 714 pregnant women was investigated. Among 232 were hospitalised in department of pathological pregnancy and 512 were under ambulatory control. In 13.4% of hospitalised patients and 2.8% healthy pregnant women the colonization of vagina or throat with GBS was stated. The greatest percentage of vagina colonization was found in patients hospitalised in connection with gestosis or because of abortions, premature delivery and inanimate fetus. No correlation was found between range of GBS colonization and trimester of pregnancy. Almost all GBS strains proved to be susceptible for commonly used antibiotics but resistant to biseptol (88.2%). Patients of hospitalised group were more often colonized not only GBS but also other potentially pathogenic microorganisms.
