Acı Su Koşullarında Avrupa Deniz Levreklerinde (Dicentrarchus labrax) Mycobacterium marinum Enfeksiyonu

Mycobacteriosis is a well-known zoonotic disease that affects both fish and human. The pathogen, Mycobacterium marinum, cause systemic and lethal disease in fish and can be observed in farmed and aquarium species. In this study, M.marinum infection was detected in European sea bass (Dicentrarchus labrax) with common clinical and pathological findings in brackish water conditions (3.92 ‰). Granulomas in the enlarged spleen and liver were observed. The pathogen was isolated on Löwenstein-Jensen (L-J) media and the molecular identification verified the causative agent as M.marinum. Several granulomas were detected in histopathological examination. European sea bass has one of the highest production numbers in Türkiye, and this study aims to present mycobacteriosis in detail with clinical and pathological effects on European sea bass from brackish water conditions.
