Abstract

NOYA-ALARCON, Oscar et al. Primer registro de triatóminos naturalmente infectados por Trypanosoma cruzi en el estado Bolívar, Venezuela . Bol Mal Salud Amb [online]. 2012, vol.52, n.2, pp.302-306. ISSN 1690-4648.

American Trypanosomiasis or Chagas disease is becoming increasingly important in the Amazon region of Venezuela, in which up to now information was lacking of the presence of Trypanosoma cruzi in triatomins, reservoirs and humans, particularly for Bolivar State, the State with the largest territory of the country, located in the South of the Orinoco River. Four specimens of Triatoma maculata were collected in the peri-domiciliar area of the community of Maniapure, in the Cedeño municipality. Two of these individuals were found naturally infected with Trypanosoma cruzi upon examination of fresh stool with presence of metacyclic trypomastigotes. Parasites were inoculated in murine models and isolated for molecular characterization. Parasite isolates were molecularly characterized as TcI. The importance of these pioneering findings should motivate the study of the vector or oral transmission of Chagas disease in this non endemic State of Venezuela.

Keywords : Triatoma maculata; Trypanosoma cruzi; Bolivar State; Amazon; Chagas Disease; Venezuela.
