title: [Ecology of serogroup B streptococci in maternity hospitals (preliminary report)].
abstract: Materials on the study of the colonization of newborns, their mothers and the medical staff of a maternity hospital by group B streptococci are presented. These streptococci were isolated from 26.3% of newborns, 19.6% of puerperae and 14.7% of the staff members. Group B streptococci were found to colonize different loci in newborns (the fauces, the nose, the umbilical cord, the ears, feces) and their mothers (the fauces, the vagina, the perianal fold, milk, the skin around the nipples, amniotic fluid, the umbilical cord). The serological typing of streptococci, isolated simultaneously from newborns and their mothers, suggested the presence of two possibilities of infecting the newborns with these microorganisms: (1) from their mothers and (2) from other newborns or members of the hospital staff during the stay in the maternity hospital.
