Antibiotic susceptibilities of group B streptococci

37816

Streptococcus agalactiae is a frequent cause of serious infections in newborn babies. It has increasingly been recognized as a pathogen in nonpregnant adults. Penicillin and ampicillin are the drugs of choice for treatment of group B streptococcus (GBS) infections.Widespread use of these antibiotics has potentated the emergence of antibiotic resistance.Total 56 isolates included in the study were recovered from vaginal swabs and ürine samples. Isolates were tested for antimicrobial susceptibility by Kirby-Bauer disk diffusion susceptibility testing method. All of the 56 clinical isolates tested were fully susceptible to penicillin, ampicillin and cephalothin. Only 8 (14.2%) and 6 (10.7%) were resistant to erythromycin and clindamycin, respectively. All of the 56 clinical isolates were not susceptible to tetracycline.
