espanolRESUMEN: El objetivo del estudio fue identificar la prevalencia de infeccion con Trypanosoma cruzi en zarigueyas (Didelphis virginiana) y Pic (Triatoma dimidiata) capturados en areas urbanas de la ciudad de Campeche, Mexico. Se colectaron 25 zarigueyas con una prevalencia de infeccion con T. cruzi del 52% (13/25). Tambien se colectaron 36 vectores de Pic con una prevalencia de infeccion del 41,6% (15/36) con T. cruzi. Todos los aislados de T. cruzi fueron TcI de acuerdo con la predominancia de este linaje en Mexico independientemente del huesped mamifero o vector. EnglishABSTRACT: The aim of this study was to identify the infection prevalence of Trypanosoma cruzi in opossums and triatomines captured in urban areas of Campeche City, Mexico. We collected 25 specimens of marsupials of Virginia opossums (Didelphis virginiana) species showing a T. cruzi infection prevalence of 52% (13/25). Also, 36 specimens of Pic (Triatoma dimiata) vectors were collected, showing a T. cruzi infection prevalence of 41.6% (15/36). All T. cruzi isolates were TcI, which correspond to the predominant lineage in mammals of Mexico, irrespective of the mammalian host species or vector.
