ABSTRACT

Chagas’ disease or American Tripanosomosis is caused by the parasite Trypanosoma cruzi. The parasite is transmited to man by feces of triatomines vectors. In North of Mexico and South of United States of America had been described a very few autochthonous cases of disease. The Breaks from Sierra Tarahumara in the State of Chihuahua, in Mexico, have similar ecosystems like States of Sonora and Sinaloa, where it had been reported the isolation of triatomines infected by T. cruzi. In this region is located the community of El Realito, in Municipality of Urique, where this study was made. The objective of this research was to determine the T. cruzi infection of captured triatomines in a mining camp in El Realito, Chihuahua, make a characterization of insects, and serologic determination of infection to workers that were bitted by triatomines. The results obtained shown the presence of T. cruzi in adult specimens of Triatoma recurva, and negative proof in ELISA tests to three workers. The finding of infected triatomines by T. cruzi in study area, demonstrate the patent wild cycle of the parasite in the region. This situation must us to be alert and make epidemiological studies in all Baja Sierra Tarahumara, to let us know a real situation of the presence of this parasite in the State of Chihuahua.
