Gross and microscopic lesions were consisted with severe pulmonary edema, multifocal myocarditis and moderate distensive cardiopathy, severe catarrhal and ulcerative gastroenteritis and non-suppurative encephalitis. At light microscopy examination of tissues stained with haematoxylin and eosin, Toxoplasma gondii tachyzoites were identified in lungs, myocardium, stomach glandular tissue, spleen, kidney and brain and both cases were positive to T. gondii using immunohistochemistry technique however, the source of infection could not be determined. In addition to the best of the knowledge this is the first confirmed report of toxoplasmosis captive Eastern grey kangaroo in Mexico.
