Characterization of Staphylococcus aureus isolated from nasal discharge from pneumonic camels (Camelus dromedarius).

In the present investigation 15 Staphylococcus aureus isolates obtained from 46 nasal swabs from pneumonic camels were characterized for their sugar fermentation, coagulase production, hemolysis and antibiotic resistance properties. The isolates were grouped into seven fermentation types, human plasma was better coagulated than cattle plasma. Beta-haemolysis was produced by eight isolates whereas seven showed α-haemolysis on blood agar. All the isolates showed multiple antibiotic resistances as they were resistant to cefepime, cefotaxime, nalidixic acid and penicillin and all isolates were sensitive to ofloxacin, ciprofloxacin, imipenem, chloramphenicol, carbenicillin and gentamicin.
