Original Paper


New myxosporean species are described from Indian fishes cultured in pond farms of Meerut, Uttar Pradesh (UP) state. Based upon plasmodia found in the Indian major carps (Catla catla, Cirrhinus cirrhosus, Labeo rohita and their hybrids), three new Myxobolus spp., Myxobolus basuhaldari sp. n., Myxobolus kalavatiae sp. n. and Myxobolus meerutensis sp. n., are described, and two species, Myxobolus catlae and Myxobolus bhadrensis, are redescribed. Plasmodia of M. basuhaldari sp. n., M. kalavatiae sp. n., M. meerutensis sp. n. and M. catlae developed in small cysts in the gill lamellae, while plasmodia and scattered spores of M. bhadrensis were found in the muscles and kidney, respectively. Plasmodia and spores found in these fishes differed from each other with respect to their morphology, tissue tropism and 18S ribosomal DNA (18S rDNA) sequence. No major pathological changes were found, but severe infections were observed.
