| Abstract | Background: Rhodnius prolixus is considered the most relevant Trypanosoma
cruzi vector in Colombia and Venezuela due it is responsible for domestic
transmission in both countries. However, a wild population of this species is
distributed in the eastern plains of the Orinoco region and Amazonia jungle,
where its epidemiological importance has not been sufficiently elucidated. This
study aimed to assess epidemiological parameters of T. cruzi transmission in
the Department of Vichada, Colombia.
Methods: We determined the characteristics of T. cruzi transmission using
entomological studies in domestic and sylvatic ecotopes. We analyzed the T.
cruzi infection in triatomine insects, identified blood meal sources, and
conducted a serological determination of T. cruzi infection in scholar-aged
children, domestic dogs, and wild hosts.
Results: Fifty-four triatomine bugs, 40 T. maculata and 14 R. prolixus were
collected in peridomestic and sylvatic ecotopes. Infected R. prolixus was
observed in La Primavera, Santa Rosalia, and Cumaribo municipalities. All the
T. maculata bugs were not infected. Serological analysis indicated that two of
3,425 children were T. cruzi positive. The seroprevalence in domestic dogs was
10,5% (49/465). Moreover, 22 synanthropic mammals were sampled, being
Didelphis marsupialis the most common. TcI genotype was detected in
seropositive dogs, R. prolixus, and D. marsupialis.
Conclusion: The present work describes extra domestic R. prolixus and D.
marsupialis in a sylvatic T. cruzi transmission cycle with transmission to humans
and domestic dogs in Colombia’s Vichada Department. | en_US |
