Abstract:

The aim of this study was to evaluate the susceptibility of Staphylococcus species isolated from the anterior nares of different Sudanese population to various antibiotics. The bacteria were isolated and identified using cultural and biochemichal procedures. Twenty five Staphylococcus isolates were applied in this study including eleven species and two sub species.They were: Staph.epidermidis, Staph.aureus, Staph.capitis, Staph.hyicus (coagulase-positive), Staph.hyicus (coagulase-negative), Staph.caseolyticus, Staph.simians, Staph.lugdunensis, Staph.delphini, Staph.schleiferi, Staph.hominis, Staph.capitis sub spp ureolyticus and Staph.Cohni sub spp ureolyticus. One isolate for Staph.hyicus coagulase-positive, Staph.cohni sub spp ureolyticus and Staph.schleiferi, three isolates for Staph.aureus, Staph.epidermidis and two isolates for the rest.The identified isolates were subjected to sensitivity test using disc diffusion method. Seventeen types of antibiotics were used: vancomycin, cefuroxime, cefotaxime, methicillin, penicillin, ampicillin, cloxacillin, ciprofloxacin, gentamicin, erythromycin, tetracycline, streptomycin, colistin, nalidixic acid, chloramphenicol, co-trimoxazol and nitrofurantoin. All of the isolates were sensitive to vancomycin, cefuroxime, cefotaxime, ciprofloxacin, gentamicin, tetracycline, streptomycin, colistin, chloramphenicol and nitrofurantoin. Antibiotics resistance -patternes were reported as: 52% for methicillin, 44% for penicillin, 36% for co-trimoxazol, 20% for ampicillin, 20% for nalidicxic acid, 12% for cloxacillin and 4% for erythromycin. Staphylococcus aureus isolates were resistant to methicillin, penicillin and nalidixic acid. Staph.epidermidis isolates were resistant to penicillin and co-trimoxazol. Staph.hyicus coagulase-positive showed multi drug resistantce. Methicillin resistance was domenant in this study.
