Henneguya salminicola Myxosporidia in Omul Muscle Tissue

A case of Myxosporidia (presumed Henneguya salminicola) found in omul muscle: macroscopic view of cysts and microscopic examination of parasite spores.

Parasitology. Today, we received samples of whitish-yellow formations found in the muscle tissues of omul. After microscopy, I observed structures characteristic of myxosporidian parasites. Based on morphological features (including spore shape and the presence of polar capsules), there is reason to believe that this could be Henneguya salminicola. I could not find any cases of omul infection with this parasite species in the scientific literature. Although omul belongs to the salmon family, infection is apparently still possible. If anyone has experience with this species or similar cases, I would be grateful for advice.
