Beta-haemolytic streptococci from the female genital tract: clinical correlates and outcome of treatment.

Clinical features, treatment and outcome were assessed retrospectively by means of a questionnaire in 174 patients in general practice whose vaginal swabs yielded beta-haemolytic streptococci. These were compared with 96 patients whose swabs yielded no recognized microbial pathogens. Patients with group B streptococci did not differ in any of these parameters from the control group, but those with group A streptococci were more likely to have vaginal soreness, a purulent discharge, and to respond to anti-streptococcal antibiotics. Implications for laboratory reporting are discussed.
