Sensitivity of brucella melitensis to chemotherapeutic agents

ABSTRACT

The sensitivity of 106 strains of Brucella melitensis to tetracycline, streptomycin, netilmicin, rifampicin, co-trimoxazole and ciprofloxacin was determined. Ninety percent of the strains were inhibited by tetracycline, netilmicin and ciprofloxacin at 1 microg/ml and by streptomycin and rifampicin at 4 microg/ml and by co-trimoxazole at 16 microg/ml. Three strains were resistant to tetracycline and one resistant to rifampicin. No resistance was found to other drugs
