Trypanosoma cruzi strains TcI and TcIV identified in Triatoma dimidiata from Mexico, Central America and Colombia as determined by 18S rDNA and SL-IR (spliced leader intergenic region) sequences. Size of the circles is proportional to the numbers of T. dimidiata specimens with a particular T. cruzi strain (TcI -dark gray or TcIV--light gray) in different countries.
