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…

Description of a xenoma-inducing microsporidian, Microgemma tincae n. sp., parasite of the teleost fish Symphodus tinca from Tunisian coasts.

The conversion of M. tincae xenomas into well-visible cyst structures or granulomas reflected an efficient host response involving the infiltration of phagocytic cells, degradation of various parasite stages and formation of a thick fibrous wall.

It is concluded that this parasite developed in the liver forming whitish xenomas that contained different developmental stages with monokaryotic nuclei, being the first description of this genus from among South America fauna.

Although juveniles apparently tolerate large parasite burdens there is some evidence of a contribution by the parasite to stress-related mortality, and the transmission of the disease and its potentially high pathogenicity to larval fishes is discussed.

This organism is described as a new species based on its site of development and its relationship among fish microsporidia based on small subunit ribosomal DNA sequence data, i.e., it was showed that it is not closely related to other microsporaidia for which ribosome DNA sequence is available thus far.
