Molecular characterization of (Myxosporea: Myxobolidae) infecting the gill lamellae of carp (Hamilton).

The present study attempted sequencing the 18S rRNA gene of infecting the gill lamellae of carp, and compared its genetic homology and phylogenetic characteristics with 18S rRNA genes of other spp. The infected fish had up to 3 small, creamy white plasmodia per gill filament with 30-50 spores each. The spore size was 17.

Prevalence, morphology and scanning electron microscopy study of myxozoan parasites.

The present study was conducted from Garia, West Bengal, India to study the Prevalence, Morphology, Severity of infestation and Scanning Electron Microscopy of Myxozoan parasites in Indian Major Carps. A total of 155 fishes were examined, out of which 80 were found infected with myxozoan parasites (51.61 %) and severity of infestation varied from 0.
