Localization of group B beta-hemolytic streptococci in the female urogenital tract.

Isolation rates of group B streptococci were determined for various sites in 100 women attending a Special Urology (VD) Clinic. Standard procedures were used for the collection of specimens, all of which were processed using a selective medium. Specimens from the urethra and lower vagina yielded significantly higher percentages of isolations than those collected from the cervix, upper vagina, and rectum. Although lower vaginal cultures yielded more positive results than urethral cultures, the difference was not significant.
