3.6 ANTIMICROBIAL SUSCEPTIBILITY TESTING
Most of the GBS isolates were susceptible to Penecilin G (89%) and Norfloxacin (83%). They were all resistant to Gentamicin and Clindamycin whereas erythomycin, tetracyclin and chloramphenicol were found to be resistant at 49%, 34% and 35% respectively. Streptomycin presented the higher intermediate activity (64%) folow by Pristinamici (44%) and Rifampicin (38%) (Figure 1).
