摘要

Chagas disease,or American trypanosomiasis,is a parasitic infection caused by the flagellate protozoan Trypanosoma cruzi.Chagas disease is mainly affecting rural populations in Mexico and Central and South America.The World Health Organization estimates that 300 000 new cases of Chagas disease occur every year and approximately 20 000 deaths are attributable to Chagas.However,this organisation classified Chagas disease as a neglected tropical disease.The economic burden of this disease is significant.In many Latin American countries,the direct and indirect costs,including the cost of health care in dollars and loss of productivity,attributable to Chagas disease ranges from$40 million to in excess of$800 million per nation per annum.So,it remains a contemporary public health concern.In chronic phase,mortality is primarily due to the rhythm disturbances and congestive heart failure that result from the chronic inflammatory cardiomyopathy(CCC)due to the persistence presence of parasites in the heart tissue.Mechanisms underlying differential progression to CCC are still incompletely understood.In the last decades immunological proteomic genetic approaches lead to significant results which help to disperse the veil covering the knowledge of the pathogenic process.Here,we reported these significant progresses.
