Çanakkale İli'ndeki bir gökkuşağı alabalığı (Oncorhynchus mykiss Walbaum) işletmesinde Pseudomonas sp. enfeksiyonu

Çanakkale ilinde bulunan bir işletmede; ortalama 91.659 ± 4.1203 g canlı ağırlığındaki gökkuşağı alabalıklarında ortaya çıkan ve ölümlere neden olan enfeksiyon araştırıldı. İncelenen balıklarda klinik olarak; vücut renginde koyulaşma ve deride peteşiyal hemoraji, gözlerde katarakt, yüzgeçlerde, operkulumda ve solungaçlarda dejenerasyon, visseral yağ artışı, bağırsaklarda seröz sıvı, dalakta büyüme, büyümüş karaciğerde soluk ve hiperemik bölgeler, safra kesesinde iltihap, böbrekte sulanma gözlendi. Hasta balıkların hepatosomatik indeksi ortalama 1.8094 ± 0.1198, spknosomatik indeksi ise 0.2149 ± 0.0173 olarak hesaplandı. Yapılan bakteriyel inceleme sonunda hastalığın Pseudomonas sp. enfeksiyonu olduğu belirlendi. Günlük olarak kg canlı ağırlığa 50 mg dozundaki Enrofloksasinin oral yolla ve 7 gün süre ile uygulandığı tedavi, enfeksiyonun kontrolünde başarılı oldu.

Pseudomonas sp. infection in rainbow trout (Oncorhynchus mykiss Walbaum) farm in Çanakkale

In this study, infection appeared in rainbow trout, average 91.659 ±4.1203 g body weight, was investigated in a farm in Çanakkale. Natural infection caused mortalities in rainbow trout with gross clinical abnormalities such as petechial haemorrhages in darkened skin, cataract in eyes, degenerations in opercula, fins arid gills, an increase of visceral fat, serous fluid in intestine, swollen spleen and necrotic liver, inflammation in gall bladder, bloody kidney. Hepatosomatic index was average 1.8094 ± 0.1198 in the diseased fish. Also, splenosomatic index was 0.2149 ± 0.0173. Disease was diagnosed Pseudomonas sp infection. 50 mg/kg fish dosage of enrofloxacin per day used for 7 d controlled the natural infection.
