Survey of medicine susceptibility in Brucella melitensis isolated from raw milk of sheep and goat in Kerman

Brucellosis is one of the most common zoonotic disease between human and cattle breeding. Brucellosis is endemic in all regions of Iran. Since brucella is an arbitrary intracellular organism and a limited range of antibiotics are effective to it, this study is based on the survey of the antibiotic sensitivity to the 9 isolated B.melitensis from raw milk in tribes population.
Antimicrobial susceptibility of 9 B.melitensis bacteria isolated from nomadic livestock population’s raw milk were studied in the laboratory. The minimum inhibitory concentration (MIC) of tested antimicrobial substances were measured by E- test. To interpret the results, CLSI standards were used for bacteria growth.
Results and 9 isolates had a high sensitivity to Doxycycline, two isolates were resistant against three antibiotics Streptomycin (MIC≥240μg/mL) Cotrimoxazole (MIC≥256μg/mL) and Rifampin (MIC≥30μg/mL) and six other isolates were showed Intermediate and sensitivity to former antibiotics. According to results, resistance to Rifampin and Streptomycin and Cotrimoxazole were the important result of this article.
