Hepatic microsporidiosis of mudskipper, Boleophthalmus dussumieri Valenciennes, 1837 (Perciformes: Gobiidae), due to Microgemma sp.

ABSTRACT: The present study reports a case of hepatic microsporidiosis caused by Microgemma sp. in brackishwater fish, Boleophthalmus dussumieri (Valenciennes, 1837) (n = 60), from the west coast of India. An eight-month study from September 2017 to April 2018 revealed a prevalence of 11.7% for this parasite. The microsporidian showed tissue-specific infection and did not reveal any gross pathology in infected fish. Small whitish cysts containing microspores of size 0.3-0.5 mm were observed in the liver of fish. The range of pyriform microsporidian spore size varied from 2.9-3.77 × 1.85-2.67 µm. Scanning electron microscopy of the spores showed a distinct groove on the anterior end of the spore for polar tube extrusion. Polymerase chain reaction (PCR) amplification of the DNA ex
