Since GBS appears to be uniformly susceptible to the penicillins, it is recommended that IV penicillin G be used instead of IV ampicillin because of penicillin G’s narrow spectrum of action, which diminishes the risk of selective pressure on other organisms and decreases the risk of ampicillin resistance. Group B Streptococcus. The SOGC is one of Canada’s oldest national specialty organizations.

For women with a high risk of anaphylaxis, clindamycin is the recommended alternative to penicillin only if the GBS isolate is known to be susceptible to clindamycin. 1 . GBS usually does not cause infections in pregnant women, the concern is for the baby.
