Abstract (2. Language): 
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, chlo-ramphenicol, 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 erythromy-cin, 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.

Bu çalışma, çeşitli gıda maddelerinden izole edilen 27 adet S. aureus suşunun, metisilin, penisilin, ampisi-lin, sefotaksim, teikoplanin, gentamisin, kanamisin, eritromisin, tetrasiklin, siprofloksasin, klindamisin, kloram-fenikol, kinopristin/dalfopristin ve linezolid gibi antibiyotiklere dirençlilik özelliklerini belirlemek amacıyla gerçekleştirildi. Antibiyotik duyarlılık testi, suşlardan %88.9’unun (24/27) en az bir antibiyotiğe dirençli oldu-ğunu ortaya koydu. S. aureus suşlarının çoğunluğu penisilin (%62.9) ve ampisiline (%59.3) dirençlilik gösterdi. Diğer antibiyotikler bakımından dirençlilik oranları, eritromisin için %22.2, sefotaksim, kanamisin ve tetrasiklin için %11.1, metisilin ve klindamisin için %7.4 idi. Üstelik, 18 suş birden fazla antibiyotiğe karşı dirençliliğe sahipti. Öyleki, suşlardan 12’si iki antibiyotiğe, 4’ü üç antibiyotiğe, biri dört antibiyotiğe ve bir suş da altı anti-biyotiğe direnç gösterdi. Bununla birlikte, tüm suşların teikoplanin, gentamisin, kloramfenikol ve linezolid’e duyarlı olduğu bulundu.
