Short-term in vitro culture and molecular analysis of the microsporidian, Enterocytozoon bieneusi

J Eukaryot Microbiol. Sep-Oct 1995;42(5):506-10. doi: 10.1111/j.1550-7408.1995.tb05896.x.


The microsporidium, Enterocytozoon bieneusi, causes a severe, debilitating, chronic diarrhea in patients with the acquired immunodeficiency syndrome. Specific diagnosis of intestinal microsporidiosis, especially due to Enterocytozoon, is difficult and there is no known therapy that can completely eradicate this parasite. Preliminary studies indicate that a short term (about 6 months) in vitro culture of this parasite yielding low numbers of spores, may be established by inoculating human lung fibroblasts and/or monkey kidney cell cultures with duodenal aspirates and or biopsy from infected patients. The cultures may subsequently be used for the isolation and molecular analysis of parasite DNA.
