Özet:

 In this study, bacterial, parasitic, and fungal analyses were carried out on 15 individuals showing disease symptoms in crayfish Pontastacus leptodactylus. Samples were collected from internal organs for pathological examinations. As a result of the pathological examinations, no parasitic and fungal pathogens agents were found. Samplings were gathered from the hepatopancreas and streaked onto tryptic soy agar TSA 96 and consequently, a pure bacterial colony was obtained. As a result of the bacterial tests, the bacteria were determined to be Aeromonas sp. genus. Narrow-clawed crayfish showed 100 mortality within 21 days of disease outbreak. Histopathologically, significant changes were observed in hepatopancreas and intestinal tissues. In hepatopancreatic tissue, prominent pathological findings characterized by prominent vacuolization in the epithelium, irregular tubules, proliferation of epithelial cells, nuclear pycnosis, and inflammatory cell infiltrations were detected. The findings of this study demonstrated that Aeromonas sp. caused important pathological findings in narrow-clawed crayfish.

 Bu çalışmada yetiştiriciliği yapılan kerevitlerde Pontastacus leptodactylus hastalık belirtileri gösteren 15 adet bireyde bakteriyel, paraziter ve fungal incelemeler yapılmış; patolojik incelemeler için iç organlardan örnek alınmıştır. İncelemeler neticesinde paraziter ve fungal patojene rastlanılmamıştır. Kerevitlerin hepatopankreasından Triptik Soy Agar TSA besiyerine yapılan bakteriyolojik ekimden saf bakteri kolonisi izole edilmiştir. Yapılan testler sonucunda bakterinin Aeromonas sp. cinsine ait olduğu belirlenmiştir. Kerevitlerde hastalık çıktıktan sonraki 21 gün içinde 100 ölüm görülmüştür. Histopatolojik olarak; hepatopankreas ve bağırsak dokularında belirgin değişiklikler olduğu gözlemlenmiştir. Hepatopankreatik dokuda; epitellerde belirgin vakuolizasyon, tübüllerde düzensizlik, epitel hücrelerinde proliferasyon, nükleer piknoz ve inflamatuar hücre infiltrasyonları ile karakterize edilen belirgin patolojik bulgular tespit edilmiştir. Bu çalışmanın bulguları Aeromonas sp.nin kerevitlerde önemli patolojik bulgular oluşturduğunu göstermiştir.
