The authors found the fibrosing chronic chagasic cardiopathy with congestive heartfailure in one out of the 21 dogs infected with the Colombian strain (five died in acutephase andfour are alive)five out of the 13 animais infected with the Berenice-78 strain eight died in acute phase) were observed until eight years of infection with T. cruzi. In view of these results, the author suggest that the dog could be a suitable experimental model for the study of the natural history of Chagas' disease. The dog conforms with the requisites of the World Health Organization (WHO) Steering Committee of Chagas' disease of the Programmefor Research Training in Tropical Diseases.
