Sensitivity of some local isolates of Mycoplasma gallisepticum against antibiotics

Abstract

Sensitivity of five local isolates ofMycoplasma gallisepticum (MG) strain and two standard MG isolates obtained from Australia were tested against antibiotics of oxytetracycline, doxycycline, erythromycin, bacitracin, vancomycin, methicillin and penicillin using antibiogram disc method. The result showed that one, 2 and 3 local MG isolates were resistent to doxycycline, erythromycin and oxytetracycline respectively . MG isolate of ADA7 from Australia was found to be resistent to all antibiotics tested. None ofthe local MG isolates were sensitive against bacitracin, vancomycin, methicillin and penicillin.
