Abstract :The causative agent of whirling disease, Myxobolus cerebralis, has a negative impact on salmonid fish and causes significant economic losses. Infected specimens of rainbow trout (Oncorhynchus mykiss) exhibiting clinical signs of whirling disease were sampled and subjected to a thorough histopathological examination in this study. The results showed M. cerebralis spores in brain, spleen, and gill tissues, with notable pathological changes such as inflammation, necrosis, and cyst formation. The study details the progression of M.cerebralis infections, highlighting significant tissue damage and immune responses in the host. The results demonstrate the importance of identifying the pathogen with histopathological methods to understand the impacts on fish health and provide insight into the host tissue response.
