    This study was performed to determine the antibiotic resistance patterns of 27 Staphylococcus aureus strains, isolated from different foodstuffs, to a range of antibiotics including methicillin, penicillin, ampicillin, cefotaxime, teicoplanin, gentamicin, kanamycin, erythromycin, tetracycline, ciprofloxacin, clindamycin, chloramphenicol, quinupristin/dalfopristin and linezolid. Antibiotic susceptibility testing revealed that 88.9% (24/27) of the strains was resistant to at least one of the antibiotics. Most of S. aureus strains showed the resistance to penicillin (62.9%) and ampicillin (59.3%). For other antibiotics, the resistance rates were 22.2% for erythromycin, 11.1% for cefotaxime, kanamycin and tetracycline, and 7.4% for methicillin and clindamycin. Moreover, 18 of the strains had resistance to multiple antibiotics. So that, 12 strains exhibited resistance to two antibiotics, four strains to three antibiotics, one strain to four antibiotics, and one strain to six antibiotics. However, all the strains were found to be susceptible to teicoplanin, gentamicin, chloramphenicol and linezolid.
