TAMAY-SEGOVIA, Paulino et al. Presence of Virginia opossum (Didelphis virginiana) and Pic (Triatoma dimidiata) infected with Trypanosoma cruzi in urban areas: preliminary evaluation in the city of Campeche, Mexico. Austral j. vet. sci. [online]. 2017, vol.49, n.1, pp.35-38. ISSN 0719-8000.  http://dx.doi.org/10.4067/S0719-81322017000100035.

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.
