“…Although the shape of the spores is similar in the Atlantic menhaden parasite and K. camarguensis, the latter has valve tips elongated by tubular extensions, 2 µm × 0.5 µm (Pampoulie et al 1999). Shape of the spores distinguished the Atlantic menhaden parasite from K. cynoglossi, K. kabatai, and K. lunata, all of which are stellate in apical view (Kovaleva et al 1979, Lom et al 1983, Obiekezie & Lick 1994. Variations in surface ornamentation further distinguished the menhaden parasite from K. kabatai, which bears posterio-lateral processes (Kovaleva et al 1979).…”

Ulcers in Atlantic menhaden Brevoortia tyrannus (Latrobe) (Clupeidae), observed along the USA east coast, have been attributed to diverse etiologies including bacterial, fungal and, recently, harmful algal blooms. To understand the early pathogenesis of these lesions, we examined juvenile Atlantic menhaden collected during their seasonal presence in Chesapeake Bay tributaries from April to October 1999 and from March to August 2000. We conducted histopathological examinations of young-of-the-year fish from the Pocomoke River tributary, which has a history of fish mortalities and high lesion prevalence. Kudoa clupeidae (Myxozoa: Myxosporea) spores were present in the muscles of fish collected in both years. Of the fish assessed by histology in April, 5 to 14% were infected, while in May 90 to 96% were infected. Infection rates remained high during the summer. Mature spores were primarily located within myomeres and caused little or no observable pathological changes. Ultrastructure showed spores with capsulogenic cells bearing filamentous projections, and a basal crescentic nucleus with mottled nucleoplasm containing cleaved, condensed chromatin. Also, a highly invasive plasmodial stage of a myxozoan was found in the lesions of juvenile Atlantic menhaden. The plasmodia were observed in fish collected between May and July, with the maximum occurrence in late June 1999 and late May 2000. Plasmodia penetrated and surrounded muscle bundles, causing grossly observable raised lesions in 73% of all fish infected with this invasive stage. Plasmodia were also detected in the visceral organs, branchial arches, and interocular muscles of some fish. Some of the invasive extrasporogonic plasmodial lesions were associated with ulcers and chronic inflammatory infiltrates. The plasmodial stage appeared to slough out of the tissue with subsequent evidence of wound healing. Ultrastructure showed plasmodia with an elaborate irregular surface, divided into distinct ectoplasm and endoplasm; the latter contained numerous spherical vegetative nuclei, secondary generative cells, and occasional cell doublets. Our ultrastructural studies indicate that the plasmodial organisms, which are important in the etiology of the skin lesions, are myxozoans, and they may represent early stages of K. clupeidae.

“…The Senegalese tonguesole, Cynoglossus senegalensis, is commercially important species in western Africa, which is mainly distributed along the coastal waters from Mauritania to Congo (Obiekezie and Lick 1994). Unfortunately, Cynoglossus fishery including C. senegalensis was overexploited in many African countries and this species is currently listed as 'Near Threatened' by the International Union for Conservation of Nature and Natural Resources Red List of Threatened Species since 2015 (Adeofe et al 2015).…”

The complete mitogenome of the Senegalese tonguesole, Cynoglossus senegalensis was determined by Illumina MiSeq platform. The complete mitochondrial genome of C. senegalensis was 16,519 bp in length. The mitochondrial genome of C. senegalensis showed a cynoglosidae-characteristic gene organization, in which translocation of control region to the position between ND1 and tRNA-Gln gene, and also inversions in tRNA-Gln gene from L-strand position to H-strand position. Phylogenetic analysis showed that C. senegalensis is most closely related to C. sinicus and S.bilineatus, which supports the previous result that genus Cynoglossidae is evolutionary paraphyletic.
