Trypanosoma cruzi is a heteroxenous parasite, i.e., it has an intermediate host, the triatomine bug, and a definitive host, the human. The triatomine bug becomes infected by the sucking blood of a contaminated person. In the bug gut the protozoan reproduces itself. When the triatomine bites another person it defecates near bite site. Basically the bitten person itches’ the region of the bite and the parasite gains the circulation of definitive host. In humans the Trypanosoma cruzi multiply as amastigote form in cardiac muscle tissue or in nervous tissue forming pseudocysts. These pseudocysts break releasing flagellate parasites in the circulation and the cycle is repeated.
