title: Selectivity of alterations in skeletal fibers in chronic Chagas' disease of the mouse.
abstract: In mice chronically infected with Trypanosoma cruzi, the masseter muscle (rich in type II fibers) was devoid of inflammatory infiltrates and parasites. In contrast, other muscles, composed of type I and II fibers, showed a decrease of type I fibers, parasites and lesions, suggesting that in T. cruzi infection type I muscle fibers are selectively damaged.
