The immune response in a dog to Encephalitozoon cuniculi infection.

Altered immune responsiveness associated with Encephalitozoon cuniculi infection in rabbits.

The variation in immune response of two unrelated colonies of laboratory rabbits to high doses of heat-killed Brucella abortus strain 19 was investigated. One was a mixed-breed, multicolored colony in which a high prevalence of encephalitozoonosis had been recorded, whereas the other rabbits were derived from a colony of Dutch-marked specific-pathogen-free rabits. Although considerable variatio...

Immune Response Against Encephalitozoon cuniculi Infection

Prevention and treatment of Encephalitozoon cuniculi infection in immunosuppressed rabbits with fenbendazole

This study was conducted to evaluate the efficacy of oral administration of fenbendazole (20 mg/kg body weight) prior to and after experimental infection of immunosuppressed rabbits with Encephalitozoon cuniculi. A total of thirty rabbits were divided into five groups: NN (non-immunosuppressed; non-infected), IN (immunosuppressed; non-infected), IPI (immunosuppressed; protected-infected), ITI (...

Lack of CD4(+) T cells does not affect induction of CD8(+) T-cell immunity against Encephalitozoon cuniculi infection.

Cell-mediated immunity has been reported to play an important role in defense against Encephalitozoon cuniculi infection. Previous studies from our laboratory have underlined the importance of cytotoxic CD8(+) T lymphocytes (CTL) in survival of mice infected with E. cuniculi. In the present study, immune response against E. cuniculi infection in CD4(+) T-cell-deficient mice was evaluated. Simil...

Optimal CD8 T-cell response against Encephalitozoon cuniculi is mediated by Toll-like receptor 4 upregulation by dendritic cells.

CD8+ T-cell immunity has been shown to play an important role in the protective immune response against Encephalitozoon cuniculi. Although earlier studies suggest that dendritic cells (DC) are important for the induction of this response, the factors responsible for initiation of the dendritic cell response against this pathogen have not been evaluated. In the current study, we demonstrate that...
