Molecular characterisation of Trypanosoma cruzi in Triatoma dimidiata from a highland locality in western Panamá

Key Points

To molecularly confirm the presence of T. cruzi in T. dimidiata and understand the transmission dynamics.
Used molecular techniques for infection confirmation.
Monitored infection prevalence and developmental stages.
Conducted field research in humid and cool ecological conditions.
Confirmed high infection prevalence of T. cruzi in T. dimidiata.
Observed multiple developmental stages of the parasite.
Indicated ongoing local transmission in the highland area.

Abstract

This study provides the first molecular confirmation of T. cruzi infection in T. dimidiata from Palmira Arriba. The combination of high infection prevalence, multiple developmental stages, and recent feeding suggests active local transmission favoured by humid and cool ecological conditions. Expanded surveillance and integrative One Health approaches are needed to elucidate transmission dynamics in highland rural Panamá.
