Abstract
Myxosporean parasites have a signiï¬Âcant role as pathogens of ï¬Âsh in wild and cultured stocks throughout the world. There are a few reports of Myxobolus species in freshwater ï¬Âsh in Turkey. The present study is part of an ongoing investigation into the characteristics of myxosporean parasites of freshwater ï¬Âsh in northeast Turkey. Thirty freshly caught specimens of the Squalius cephalus were purchased from ï¬Âshermen at Ladik Lake, Samsun, Turkey between August 2015 and October 2015. All organs were also examined for plasmodia of myxosporean parasites under a stereo microscope. The plasmodia type of gill-infecting species was classiï¬Âed lamellar, ï¬Âlamental, and gill arch type. Infected gills were ï¬Âxed in 10% neutral formaldehyde and routinely processed, embedded in paraffin. Tissue sections 4–6 μ in width were stained with hematoxylin-eosin and examined a light microscope. The histological analysis revealed the development of the cyst-like plasmodia as intraï¬Âlamentalvascular type. Plasmodia based on SSU rRNA gene was ampliï¬Âed and sequenced at Macrogen. The sequence was compared with previously published data for identiï¬Âcation by using BLAST via Genbank. Myxobolus infection was found in 5 (16.6%) of 30 S. cephalus. Molecular analysis of the SSU rRNA gene conï¬Ârmed the myxosporean species as a Myxobolus muelleri. This is ï¬Ârst report of histopathological and molecular data of Myxobolus muelleri in S. cephalus from Ladik Lake, Turkey to date.
