Calcofluor white 2MR, modified trichrome blue, and indirect immunofluorescent antibody (IFA) staining methods were evaluated and compared for detecting microsporidia in stool. Serial 10-fold dilutions of Encephalitozoon (Septata) intestinalis were prepared in three formalinized stool specimens or in Tris-buffered saline. Ten-microliter aliquots were smeared(More)
Microsporidia cause opportunistic infections in AIDS patients and commonly infect laboratory animals, as well. Euthymic C57B1/6 mice experimentally infected with intraperitoneal injections of 1 x 10(6) Encephalitozoon cuniculi Levaditi, Nicolau et Schoen, 1923, Encephalitozoon hellem Didier et al., 1991, or Nosema corneum Shadduck et al., 1990 displayed no(More)
During a screening for monoclonal antibodies (MAbs) to the microsporidian Encephalitozoon hellem, three murine hybridoma cell lines producing strong enzyme-linked immunosorbent assay (ELISA) reactivities were cloned twice, were designated C12, E9, and E11, and were found to secrete MAbs to the immunoglobulin M isotype. On subsequent ELISAs, the three MAbs(More)
Giardia spp. and Cryptosporidium spp. are intestinal parasites that affect humans and animals throughout the world. Although infection with Giardia spp. is usually self-limiting, some cases result in mild to severe enteritis. Giardiasis can be treated with modern drugs. The increasing incidence of well-documented outbreaks of Cryptosporidiosis has resulted(More)
