Resistotyping of Camel Skin Wounds Associated Staphylococcus aureus on the Basis of Multidrug Resistance Pattern

The present investigation was attempted to type Staphylococcus aureus associated with camel skin wounds on the basis of multidrug resistance pattern against 35 antibiotics of different generations. Beta-lactamase activity was also determined for the isolates. Twenty six S. aureus isolates were obtained from camel skin wounds and confirmed by 23S rRNA gene ribotyping. We recorded susceptibility of 100% isolates to azithromycin, netillin, polymixin-B and rifampicin followed by susceptibility of 96.15% isolates to chloramphenicol and gentamicin, 92.30% to bacitracin, novobiocin and cloxacillin, 88.46% to clindamycin, 84.61% to tobramycin, 80.77% to erythromycin, 69.23% isolates were sensitive to ceftriaxone, methicillin, doxycycline hydrochloride, cefaclor, ciprofloxacin, norfloxacin, ofloxacin, amoxicillin, amoxyclav, sparfloxacin and trimethoprim. Nineteen different resistotypes were identified with 0.9508 discriminatory index. This higher number of resistotypes and more discriminatory index may suggest higher diversity and resistance in the isolates. The continuous local surveillance and genotypic explorations should be performed on regular basis in order to have adequate information for antibiotic resistance patterns of S. aureus infections.
