THE INCIDENCE AND ANTIBIOTIC RESISTANCE OF COAGULASE POSITIVE STAPHYLOCOCCUS AUREUS IN SEAFOODS MARKETED IN IZMIR

Abstract

The aims of this study are to check the prevalence of coagulase-positive Staphylococcus aureus in raw and ready-to-eat seafoods samples in İzmir and to determine the antibiotic resistance of the isolates. For this purpose, 50 samples of raw and ready-to-use seafoods were analyzed. As a result of the study, coagulase positive S. aureus was detected in 24 (58%) raw and 26 (46%) ready-to-eat seafoods. While all S. aureus isolates were susceptible to ceftazidime, gentamycin, clindamycin, nitrofurantoin, ofloxacin, oxacillin, rifampicin, vancomycin and amicasin, the isolates were resistance to amoxicillin-clavulanic acid and ciprofloxacin (7.7%), cephalotine (3.8%), meticillin (30.8%), penicillin (80.8%), linezolid (19.2%). Coagulase positive S. aureus is considered a potential hazard to consumers and food safety. Hygiene and sanitation conditions must be considered during production and sales areas in order to prevent the contamination of this bacterium with seafood.

İZMİR’DE SATIŞA SUNULAN SU ÜRÜNLERİNDE KOAGÜLAZ POZİTİF STAPHYLOCOCCUS AUREUS’UN İNSİDANSI VE ANTİBİYOTİK DİRENCİ

Abstract

Bu çalışmanın amacı, İzmir’de satışa sunulan çiğ ve tüketime hazır su ürünlerinde koagülaz pozitif Staphylococcus aureus varlığının tespit edilerek, antibiyotik dirençlerinin belirlenmesidir. Bu amaçla çiğ ve tüketime hazır su ürünlerinden oluşan 50 örnek analiz edilmiştir. Araştırma sonucunda, 24 çiğ su ürününün %58’inde ve 26 tüketime hazır su ürününün %46’sında koagülaz pozitif S. aureus tespit edilmiştir. İzole edilen tüm S. aureus suşları, seftazidim, gentamisin, klindamisin, nitrofurantoin, ofloksasin, oksasilin, rifampisin, vankomisin ve amikasine duyarlı bulunurken, izolatların %7,7’si amoksisilin-klavulanik asit ve siprofloksasine, %3.8’i sefalotine, %30.8’i metisiline, %80.8 penisiline ve %19.2’si linezolide dirençli bulunmuştur. Koagülaz pozitif S. aureus tüketiciler ve gıda güvenliği için potansiyel bir tehlike olarak değerlendirilmektedir. Bu patojenin gıdalara bulaşmasını engellemek için, üretim ve satış alanlarında hijyen ve sanitasyon koşullarına dikkat etmek gerekmektedir.
