Encephalitozoon cuniculi Infection in Rabbits

intracellular parasite in the phylum Microspora, which is defined by its resistant spore stage. Microsporidia receive little attention in veterinary medical curricula because they are considered important only as parasites of rabbits and fish. Microsporidia are important parasites of humans as well, with some species causing severe disease and death in immunocompromised individuals. Microsporid...

A new vesicular compartment in Encephalitozoon cuniculi.

The microsporidia are emerging human and veterinary pathogens known to infect every tissue type and organ system. Their infectious spore possesses a number of peculiar organelles, including the diagnostic polar tube. In a proteomics-driven effort to find novel components of this organelle in the human-pathogenic species Encephalitozoon cuniculi, we unexpectedly discovered a protein which locali...

Immune Response Against Encephalitozoon cuniculi Infection

Cytokine response to infection with the microsporidian, Encephalitozoon cuniculi.

The production of three cytokines, interferon gamma (IFN-gamma), interleukin 10 (IL-10) and interleukin 12 (IL-12), was measured after intraperitoneal infection of immunocompetent Balb/c mice and immunodeficient SCID mice with the microsporidian, Encephalitozoon cuniculi Levaditi, Nicolau et Schoen, 1923. High levels of IFN-gamma were detected in ex vivo cultures of peritoneal exudate cells (PE...

Prevalence of antibodies to Encephalitozoon cuniculi in horses from Brazil.

Encephalitozoon cuniculi has been associated with natural cases of abortion and stillbirth in horses. However, little is known about the prevalence of this parasite in horses. We examined sera from 559 horses from Brazil for antibodies to E. cuniculi using the indirect immunofluorescent antibody (IFA) test and the direct agglutination test (DAT). We found that 79 (14.1%) were positive in the IF...
