Description of Myxidium tetraodoni Sp. Nov., Myxidium anisocapsularis Sp. Nov. and Myxobolus magai Sp. Nov. (Myxosporea: Bivalvulida) Infecting Some Freshwater Fishes in Cameroon (Central Africa)

Abstract

Examination of some Teleost fishes captured in the Maga detention lake located in the Far North Region of Cameroon, revealed the presence of three new species of Myxosporidia of the genera Myxidium Bütschli, 1882 and Myxobolus Bütschli, 1882 of which complete description is given in the present study. These species are: Myxidium tetraodoni sp. nov., parasite of the urinary bladder of Tetraodon lineatus Linnaeus, 1758 (Tetraodontidae) that form ellipsoidal spores with a turgid middle part and rounded ends. They measured 11.6 (10.5-12.5) µm long × 8.2 (7.2-9.6) µm broad; the spherical polar capsules are of equal size and measure 3.

Myxobolus opsaridiumi sp. nov. (Cnidaria: Myxosporea) infecting different tissues of an ornamental fish, Opsaridium ubangiensis (Pellegrin, 1901), in Cameroon: morphological and molecular characterization

“…In addition to its high-quality meat and rapid growth, species of the genus Opsaridium play an important role in national and international pet trades as ornamental (aquarium) fish. Until now, more than 270 species of Myxosporea have been reported to infect African fishes (Deli et al 2017) and none were known to infect O. ubangiensis.…”
