Türkiye'de Kültürü Yapılan Sinarit Balıklarında (Dentex dentex) İlk Vibrio harveyi Enfeksiyonu Bildirimi

Bu çalışmada, Türkiye'de yetiştiriciliği yapılan hasta sinarit balıklarından (Dentex dentex) Vibrio harveyi izole edilmiştir. Hastalık Temmuz ayında (2013), juvenil sinarit balıkları kuluçkahaneden yüzer kafes sistemlerine transfer edildikten sonra ortaya çıkmıştır. Hasta balıklardan 20-25 g ağırlığındaki 5 birey yüzer kafeslerden seçilmiş ve karaciğer, dalak, böbrek ve göz dokusundan örnekler alınmıştır. Bakteriyolojik kültür sonucunda 8 adet izolat saf olarak elde edilerek biyokimyasal karakterizasyonun yanı sıra 16S rRNA geni dizi analizi ile tanımlanmıştır. Bu çalışma, Türkiye'de kültürü yapılan sinarit balıklarında Vibrio harveyi enfeksiyonunun rapor edildiği ilk çalışmadır.

First Report of Vibrio harveyi Infection in Diseased Common Dentex (Dentex dentex) Cultured in Turkey

In the present work, Vibrio harveyi was consistently isolated from diseased common dentex (Dentex dentex) cultured in Turkey. The outbreak occurred in July (2013), following the transportation of common dentex juveniles from hatchery to offshore floating cages. Five moribund cultured common dentex individuals, about 20-25 g in weight, were selected from the said floating cages and samples were taken from internal organs including liver, spleen, kidney and eye tissue. A total of eight pure cultures were obtained and identified through basic biochemical characterisation as well as 16S rRNA gene sequencing. To our knowledge, this is the first report of Vibrio harveyi infection in cultured common dentex in Turkey.
