Cutaneous leishmaniasis is frequent in equines from an endemic area in Rio de Janeiro, Brazil.

abstract：:Acute infection with Trypanosoma cruzi results in intense myocarditis, which progresses to a chronic, asymptomatic indeterminate form. The evolution toward this chronic cardiac form occurs in approximately 30% of all cases of T. cruzi infection. Suppression of delayed type hypersensitivity (DTH) has been proposed as a...
