An experimental infection of Trypanosoma cruzi in striped skunks (Mephitis mephitis). 1980

D S Davis, and L H Russell, and L G Adams, and R G Yaeger, and R M Robinson

Four adult (3 male, 1 female) captive-raised, decented, striped skunks (Mephritis mephitis) were infected experimentaly with a field strain (Texas-Tulane) of Trypanosoma cruzi, originally isolated from a naturally-infected dog. Two skunks were injected intravenously with approximately 4.5 x 10(6) viable T. cruzi trypomastigotes. Two skunks were inoculated per os and per conjunctivum with 10 ml of phosphate buffered saline containing macerated, T. cruzi-infected triatomine intestines and intestinal contents. The skunks had minimal clinical manifestations with no mortalities occurring during 46 days post-exposure. Sera from all skunks were positive at 24 days post-inoculation (PI) by the direct and latex agglutination tests. Blood cultures from the 4 skunksd were positive for T. cruzi at day 24 PI and 3 were positive at day 46 PI. All skunks had mild to moderately severe chronic granulomatous myocarditis of the atria and ventricles. Typical T. cruzi amastigotes were present within myocardial fibers in 3 of 4 skunks.

D014355 Chagas Disease Infection with the protozoan parasite TRYPANOSOMA CRUZI, a form of TRYPANOSOMIASIS endemic in Central and South America. It is named after the Brazilian physician Carlos Chagas, who discovered the parasite. Infection by the parasite (positive serologic result only) is distinguished from the clinical manifestations that develop years later, such as destruction of PARASYMPATHETIC GANGLIA; CHAGAS CARDIOMYOPATHY; and dysfunction of the ESOPHAGUS or COLON.
