ABSTRACT Microfilum lutjani n. g., n. sp. (Microsporida) was found on the gill filaments of Lutjanus fulgens (Teleost) inhabiting the coasts of Senegal. This microsporidium forms xenomas distinguished by the microvilli covering the plasma membrane. At all stages of development individuals have isolated nuclei and are in direct contact with the host cytoplasm. Merogony is binary and sporogony is tetrasporoblastic. the spore (4.75 times 2.60 μm)) is characterized by a manubrium inserted on a laterally offset anchoring disc and extending into a very short, noncoiled polar filament (no longer than 500 nm) in the form of a hook. This type of polar filament has not been described previously in the Microsporida. 相似文献

Six new species of coccidian parasites of fish are described from the coast of Senegal: Goussia dakarensis sp.n. from Brachydeuterus auritus, Pomadasys peroteti and Galeoides decadactylus; Goussia decapteri sp.n. from Decapterus rhonchus; Goussia exoceti sp.n. from Hirundichthys affinis; Goussia emissolei sp.n. and Goussia soumbediounensis sp.n. from Leptocharias smithii; and Goussia trachinoti sp.n. from Trachinotus ovatus. Goussia clupearum (Thélohan, 1894) was found in eight new host species and G. senegalensis Faye, 1988 in one new host species. 相似文献
