Abstract

The study was carried out with the aim to isolate Staphylococcus aureus from camel and goat raw milk and determine their antimicrobial susceptibility pattern. 204 raw milk samples were collected from randomly selected lactating camels (n=62) and lactating goats (n=142) in live-stock producing pastoralists’ areas of Somali region for isolation and identification of S. aureus. Antibiotic susceptibility tests were performed on all S. aureus isolates to 16 antibiotics by Kirby-Bauer disk diffusion method. Twenty three (11.27% of the total) S. aureus strains were isolated. Four (6.45%) strains were isolated from camel raw milk samples and 19 (13.34%) from  goat raw milk samples. S. aureus isolates showed resistance to Nalidixic acid, Polymixin B, and Penicillin G. S. aureus isolates were sensitive to vancomycin, ciprofloxacin, cefoxitin, cephalotin, gentamycin, Doxycycline, kanamycin, trimethoprim-sulfamethoxazole, chloramphenicol, norfloxacin, and erythromycin. Multi drug resistance was detected in 69.2% of the isolates. The present study has demonstrated the existence of alarmingly high level of multiple antimicrobial resistances of S. aureus among camel and goat milks.
