Abstract

In this study, moribund
salema (Sarpa salpa) individuals from
a public aquarium were investigated to identify the cause of disease. A minor
scale loss and partial skin depigmentation were observed in the diseased fish. Internal
investigation of fish revealed hyperemia
in the liver and the intestines and haemorrhages in the muscle tissues. When the histopathological sections of
tissues were examined, it was determined that the bacterial infection affected especially
the gill epithelium, the intestinal mucosa, the heart muscle and hemopoietic
tissues of the spleen. According to phenotypic and biochemical characteristics
as well as SSU rRNA sequencing results, the isolated bacteria was Vibrio harveyi and consistently seen all
the examined samples of visceral organs including kidney, spleen, liver and
blood. However, we need to emphasize that Vibrio
vulnificus and Pseudoalteromonas
piscicida bacteria were also isolated from blood and spleen tissues of one
sick fish among others.

Bir Deniz Akvaryumunda Salpa Balıklarında (Sarpa salpa) Vibrio harveyi Enfeksiyonu Olgusu: ilk rapor

Abstract

Bu çalışma, bir deniz
akvaryumundan alınan hasta salpa balıklarında (Sarpa salpa) hastalığa neden olan etken veya etkenleri tanımlamak
üzere yapılmıştır. Hasta balıkların vücudunda hafif şiddette deri renginde
açılma ile birlikte pul kayıpları gözlenmiştir. İç bakıda, karaciğer ve
bağırsak dokularının hiperemik ve kas dokusunun da hemorajik olduğu tespit
edilmiştir. Doku kesitleri histopatolojik olarak incelendiğinde, enfeksiyonun;
özellikle solungaç epitelyumu, bağırsak mukozası, kalp kası ve dalağın hematopoetik
dokusunu etkilediği belirlenmiştir. Fenotipik ve biyokimyasal özellikleri ve
SSU rRNA dizileme sonuçlarına göre; incelenen tüm iç organlardan (böbrek,
dalak, karaciğer) ve kan dokusundan Vibrio
harveyi bakterisi izole edilmiştir. Buna ek olarak, incelenen balıklardan sadece
birinin kan dokusundan ve dalağından alınan örneklerde Vibrio vulnificus ve Pseudoalteromonas
piscicida bakterileri de izole edilmiştir.
