Isolated 160 food-borne pathogens screened for antibiotics test using 22 different antibiotics. Antibiotic resistance pattern showed by Staphylococcal isolates were grouped and results represented by one individual strain from the MDR group. MDR (multidrug-resistance) coagulase positivea, coagulase negativeb Staphylococcal resistance to antibiotics belonging to three or more class; n-number of isolates andc mecA gene negative isolate. Abbreviations: AMP- amphicilin, AZM-azithromycin, AMC- amoxyclav, B- bacitracin, CFM- cefoxitin, CTX- cefotaxime, C- chloramphenicol, CIP- ciprofloxacin, CD- clindamycin, COT- co-Trimoxazole, E- erythromycin, GEN- gentamycin, K- kanamycin, LZ- linezolid, NIT- nitrofurantoin, NX- norfloxin, OX-oxacillin, P- pennicilin, RIF- rifampicin, S- streptomycin, TE- tetracycline, and TOB- tobramycin. The most frequently occurring phenotype in MDR stains was OX-P-TE (Tri-Abi) and AMP-AZM-AMC-RIF-TE (Penta-Abi).
