Neosporosis in a Captive Parma Wallaby (Macropus parma)

Infection with Neospora caninum has been diagnosed in a variety of animal species; however, reports in marsupials are rare. A captive Parma wallaby (Macropus parma) died suddenly and was subjected to necropsy examination. The main finding was necrotizing myocarditis associated with protozoan parasit...

Description
Summary:Infection with Neospora caninum has been diagnosed in a variety of animal species; however, reports in marsupials are rare. A captive Parma wallaby (Macropus parma) died suddenly and was subjected to necropsy examination. The main finding was necrotizing myocarditis associated with protozoan parasites. The protozoa were identified as N. caninum by use of immunohistochemistry and partial gene sequence analysis. Neospora and Toxoplasma should be considered a possible cause of disease in captive marsupials. Further work is required to determine whether marsupials are an accidental or terminal host of this protozoan in order to better understand the host–parasite relationship.
