Trypanosomiasis cruzi: a follow-up study of tissue reacting immunoglobulins in infected purebred pinscher dogs

Antibodies against striated muscle (cardiac and skeletal) were studied in serum samples from 36 purebred prepubertal Pinscher dogs (15 Controls without infection and 21 infected with Trypanosoma cruzi from 7 to 400 days after infection with 1000 trypomastigotes/gram body weight of the Colombiana strain by the intraperitoneal route). Although three different immunohistological pattems of tissue-reacting immunoglobulins were found their presence was not correlated with any peculiar characteristics or with the severity of the disease in each particular dog.
