Abstract

This study was carried out to determine the aethiological agent of an infectious fish disease that induced high mortality in a guppy production unite. Affected fish (2-4 g in weight) showed pale gills, darkening of the skin, fin rot, aimless swimming, loss of uqilibrium, convulsions, paralysis, and death. Internally pale liver and kidney, enlarged cherry red spleen and swollen bile duct were noticed. Bacteriological inoculations were made from the infected fish kidney, liver and spleen to Tryptic Soy Agar (TSA) and Anacker and Ordal Agar (AOA). The isolated bacteria were identified according to cellular morphological, physical, and biochemical characteristics. From this epizootic, 4 isolates were identified as Flavobacterium spp. and 2 isolates as Pseudomonas fluorescens, were recovered. Oxytetracycline was found most sensitive to both bacteria isolate. Sick fish treated with this antibiotic in food was found effective with seven days application.

Özet

Bu çalışma özel sektöre ait bir Iepistes üretim ünitesindeki balıklarda görülen ve yüksek mortaliteye neden olan enfeksiyöz bir hastalığın etkenini saptamak amacı ile yürütüldü. Hasta balıklarda (2-4 gr. ağırlığında) dış bakıda solungaçlarda solgunluk, anormal yüzme davranışları, denge kaybı, renkte koyulaşma, yüzgeçlerde erime, çırpınma, durgunluk ve ölüm gözlendi. İç bakıda karaciğer ve böbreklerinin solgunlaştığı, dalaklarının koyulaştığı ve safra keselerinin ise şişkin olduğu dikkati çekmiştir. Hasta Iepistes balığı örneklerinin böbrek, karaciğer ve dalak gibi iç organlardan Tryptic Soy Agar (TSA) ve Anacker and Ordal Agar'a (AOA) 'bakteriyolojik ekimleri yapıldı. İzole edilen bakteriler morfolojik, fiziksel ve biyokimyasal özelliklerine göre identifiye edildi. Bu çalışmadan elde edilen dört izolat Flavobakterium spp.iki izolat ise Pseudomonas fluorescens olarak identifîye edildi. Oxytetracycline her iki bakteri türüne de duyarlı bulunduğu için hasta balıklara yem içinde verilerek ölümler durduruldu.
