The antibiotic susceptibility profiles of 52 clinical isolates of GBS were evaluated to 12 antibiotics. If they have checked the group B strep sensitivities and it is sensitive to clindamycin then that is also an option. For a penicillin-allergic high anaphylaxis risk women with unknown GBS sensitivity results then vancomycin 1 gram IV every 12 hours until delivery should be administered.
However clindamycin-resistant germs cause. Treatment will depend on the kind of infection caused by GBS bacteria. V or vancomycin 2 gramsday I.
If skin testing was negative intrapartum antimicrobial prophylaxis with intravenous penicillin was administered. Clindamycin can also be used to treat adult GBS infections if the patient has a severe penicillin allergy. Group B streptococcus is generally susceptible to penicillin but E.
Of 28 patients with both GBS colonization and penicillin allergy 25 89 had negative skin testing to penicillin and received intrapartum penicillin for GBS prophylaxis without adverse reactions. Antibiotic sensitivities were determined using disk diffusion and microdilution methods according to the guidelines of the National Committee. Group B Strep Comes Back.
Aminoglycosides have little to no activity against group B streptococci when used alone but provide synergistic activity when combined with ampicillin or penicillin G. More than 40 of GBS infections. Table 2 17 18 lists oral antibiotics that are acceptable treatment choices.

Vancomycin should be used prudently because it is not as effective for IAP as clindamycin and is a drug of last resort for gram positive. Ampicillin azithromycin cefamandole cefazolin ceftriaxone ciprofloxacin clindamycin erythromycin nitrofurantoin ofloxacin penicillin and vancomycin.
