Epidemiologia da Doença de Chagas Canina no Semiárido Paraibano e alterações cardiovasculares em cão naturalmente infectado por Leishmania (Leishmania) infantum chagasi.

Abstract

Chagas disease and visceral leishmaniasis are parasitic chronic diseases in dogs, both are considered antropozoonoses classified as neglected diseases, with the character of permanent challenge to public health. However there are several factors to be disclosed regarding factors that interposes the canine Chagas disease considering the characteristics of semi-arid bio paraibano well as its role and the epidemiological cycle of T. cruzi. With regard to leishmaniasis, a character under clinical manifestations are similar in dogs and humans and can progress to more severe forms evolve and various organs is difficult therapeutic and epidemiological issues remain to be clarified and etiopathogenic, especially when there cardiac involvement. Thus, the aim of this research to determine the epidemiology of Chagas disease in rural semiarid northeastern Paraiba, or not, raising the dogs to a variable to be considered and assisted in the chain of disease transmission, considering the conditions of the biogeographic region, and highlight the cardiac involvement with clinical and pathological in a dog naturally infected by Leishmania (Leishmania) infantum chagasi. From the results it was possible to obtain information pertaining to the epidemiological situation of Chagas Disease highlighting biogeographical characteristics of rural semi-arid region of Paraiba, raising dogs and the risk factors disclosed in the highlighted contact with birds and ecotopes operationalizing indicators to be watched and considered in the chain of transmission of the disease in the region. And as evidenced in this description chronic myocarditis in a dog carrier Visceral Leishmaniasis, etiopathogenic aspects on the myocardium in this case may be related primarily to the presence of the parasite, or to the response "reactive nonspecific" tissue aggression of the parasite in the body. However it is not known whether the strains of Leishmania infantum chagasi in the semi-arid of Paraíba have some tropism for cardiac tissue or induce immunological cross-reaction with clinical implications.
