Microsporidiosis in a young ostrich (Struthio camelus)

Avian Dis. Oct-Dec 1998;42(4):832-6.

Abstract

Microsporidia are obligate, intracellular, protozoan parasites of a wide variety of vertebrates and invertebrates. Confirmed reports of microsporidial infection of avian species are few (lovebirds, a parrot, and a group of budgerigar chicks). At slaughter, a 14-mo-old ostrich was found to have small intestinal serosal hemorrhages during postmortem inspection. Histologic examination of the small intestine revealed a chronic lymphoplasmacytic to purulent enteritis with mucosal hyperplasia, muscular hypertrophy, and numerous microsporidia that were located within the superficial enterocytes and the lamina propria. Microsporidia have a ubiquitous distribution in nature and are suspected as possible zoonotic agents.
