trypanosoma cruzi circulating in the southern region of the state of mexico (zumpahuacan) are pathogenic: a dog model.	here we describe clinical and pathologic evidence of chagas disease caused in dogs by circulating trypanosoma cruzi from a newly recognized endemic area in mexico. we show that the zumpahuacan isolate, although less virulent than the sylvio-x10 reference strain that caused acute myocarditis and death, was pathogenic in dogs. dogs infected with the zumpahuacan isolate exhibited electrocardiographic alterations, left- and right-ventricle dilation, and hydropericardium. histologically, diffused per ...	2009	19706902
