Nosematosis of the Cornea

Human microsporidial infections

“…layers of corneal lamellae, and a marked inflammatory reaction, including mononuclear, neutrophil, and epitheloid infiltration, was present (5,25,26,32,61,161,193). No systemic microsporidial infection was noted in any of these patients.…”

“…Meronts and sporonts were not seen, and nucleation was not observed. Microsporidium africanum was detected in the corneal stroma of a woman from Botswana suffering from a perforated corneal ulcer (161). Developmental stages of the parasite were not seen.…”

Human microsporidial infections.

“…The parasites involved, Nosema sp. and Nosemalike organisms of the nontaxonomic group Microsporidium, were found deep in the corneal stroma with spores contained within phagocytic cells and lying free between the fibrous layers of corneal lamellae, and a marked inflammatory reaction, including mononuclear, neutrophil, and epitheloid infiltration, was present (5,25,26,32,61,161,193). No systemic microsporidial infection was noted in any of these patients.…”

Microsporidia and human infections.

“…Two cases of corneal infection have been reported in the literature (2,46) and we are aware of a third (R. M. Davis, personal communication). Unfortunately, it was not possible to determine precisely the genus and species of the parasites, but they have been variously placed in the genus Nosema or a new genus, Microsporidium (12).…”
