Abstract

A case of microsporidian (Glugea sp.) infection in the greasy grouper, Epinephelus tauvina (Forsskal) was studied by light microscopy as well as histological examination. The parasite was located in the subcutaneous tissue and visceral organs, forming spherical blackish xenomas of about 1-2.5 mm in diameter surrounded by a layer of connective tissue. The observed characteristics of the parasite are in line with those of the other Glugea species; showing merogony in the outer zone of the cytoplasm of the host cell, sporogony in sporophorous vesicles, and mature ovoid spores 4-6.5 μm x 2-2.2 μm located in the central part of the blackish xenoma. These characteristics suggested that the microsporidian which was found to infect E. tauvina during the present investigation was Glugea sp.
