Mersin'de tüketime sunulan gökkuşağı alabalıklarında (Oncorhynchus mykiss Walbaum, 1792) Motil Aeromonas'ların araştırılması ve mezofilik aerobik bakteri sayımı

Bu çalışmada, zoonotik hastalık etkenlerinden Motil Aeromonas’ların Mersin ilindeki üç farklı markette insan tüketimine sunulan Gökkuşağı alabalıklarındaki (Oncorhynchus mykiss, Walbaum, 1792) varlığı araştırılarak insan sağlığı yönünden bir sakınca oluşturup oluşturmadıkları tespit edilmeye çalışılmıştır. Balıkların genel mikrobiyolojik durumu hakkında bilgi edinebilmek amacıyla mezofilik aerobik bakteri sayımı yapılmıştır. Bu amaçla Kasım 2003 ve Haziran 2004 tarihleri arasında toplam 120 adet balık incelenmiştir. Gökkuşağı alabalıklarının hiçbirinde Motil Aeromonas izole edilememiştir. Balıkların deri, kas, iç organ ve bağırsak içeriklerinden elde edilen mezofilik aerobik bakteri sayılarının 8 aylık ortalama değerleri 1. markette sırasıyla 7,4x105, 4,5x104, 6,9x104 ve 1,1x107, 2. markette 6,8x104, 5,4x103, 8,3x103 ve 4,9x106 ve 3. markette 1,7x105, 1,3x104, 1,1x104 ve 2,9x106 KOB g-1 olarak bulunmuştur.

An Investigation of motil aeromonads and mesophilic aerobic bacteria count in rainbow trout (Oncorhynchus mykiss Walbaum, 1792 marketed in Mersin

An investigation of motil aeromonads and mesophilic aerobic bacteria count in rainbow trout (Oncorhynchus mykiss Walbaum, 1792) marketed in Mersin. In this study, Rainbow trout, sold at three different outlets in Mersin, were tested for motil Aeromonads, zoonose disease agents. 120 samples were collected and analysed from November 2003 to June 2004. Motil Aeromonads were not isolated in any of the Rainbow trout samples. The 8 month mean values of mesophilic aerobic bacteria count of the skin, muscle, organs and intestine of the fishes were at the 1. outlet respectivly 7,4x105, 4,5x104, 6,9x104 and 1,1x107; at 2. outlet 6,8x104, 5,4x103, 8,3x103 and 4,9x106 and at 3. outlet 1,7x105, 1,3x104, 1,1x104 and 2,9x106 CFU g-1.
