Vaginal swab: Group B streptococcus – Shipped February 2012
A simulated vaginal swab sample collected from a 25 year old pregnant woman who was reported to be allergic to penicillin was sent to category A and B laboratories for Group B Streptococcus screening.
Participants were expected to isolate and report Group B Streptococcus and were asked to report susceptibility to clindamycin and comment on any other antimicrobial agent they would normally report.
MAIN EDUCATIONAL POINTS from M114-3
- It is important to test for group B streptococci in pregnancy, usually at 35-36 weeks gestation, but even intrapartum if pre-natal care has not been adequate.
- Antibiotic choices are penicillin, clindamycin and vancomycin.
