Four methods (streak plate, pour plate, selective broth, and direct fluorescent antibody staining) were evaluated for their ability to detect group B streptococcal colonization in parturient women and their offspring. When colonization was defined as a positive culture by any method from any site, selective broth was the most sensitive method, detecting 100% of colonized mothers and infants at birth and 48 h of age. This method failed to detect only one colonized individual (infant at 24 h of age). The other three methods detected from 20 to 56% of colonized individuals.
