Observations on the histopathological changes caused by myxosporidian infections in minor carps.

Myxozoan infections result in large scale histopathological features depending on various factors. Earlier studies on pathological changes caused by myxozoan infections in piscine hosts have been reported from different localities. This study is based on the histopathological features caused by the members of genera Myxobolus Bütschli, 1882 and Thelohanellus Kudo, 1933 in the gill and fin tissues of commercially significant minor carps, Labeo calbasu and Labeo gonius of the genus Labeo collected from the four different districts of the north-eastern Indian state of Tripura (latitude 22°51'-24°32'N and longitude 90°10'-92°21'E) spanning over a total geographical area of 10,491 km(2).
