Ecological host fitting of Trypanosoma cruzi TcI in Bolivia: mosaic population structure, hybridization and a role for humans in Andean parasite dispersal

et al. 2015

An improved understanding of how a parasite species exploits its genetic repertoire to colonize novel hosts and environmental niches is crucial to establish the epidemiological risk associated with emergent pathogenic genotypes. Trypanosoma cruzi, a genetically heterogeneous, multi‐host zoonosis, provides an ideal system to examine the sylvatic diversification of parasitic protozoa. In Bolivia, T. cruzi I, the oldest and most widespread genetic lineage, is pervasive across a range of ecological clines. High‐resolution nuclear (26 loci) and mitochondrial (10 loci) genotyping of 199 contemporaneous sylvatic TcI clones was undertaken to provide insights into the biogeographical basis of T. cruzi evolution. Three distinct sylvatic parasite transmission cycles were identified: one highland population among terrestrial rodent and triatomine species, composed of genetically homogenous strains (A r = 2.95; PA/L = 0.61; DAS = 0.151), and two highly diverse, parasite assemblages circulating among predominantly arboreal mammals and vectors in the lowlands (A r = 3.40 and 3.93; PA/L = 1.12 and 0.60; DAS = 0.425 and 0.311, respectively). Very limited gene flow between neighbouring terrestrial highland and arboreal lowland areas (distance ~220 km; FST = 0.42 and 0.35) but strong connectivity between ecologically similar but geographically disparate terrestrial highland ecotopes (distance >465 km; FST = 0.016–0.084) strongly supports ecological host fitting as the predominant mechanism of parasite diversification. Dissimilar heterozygosity estimates (excess in highlands, deficit in lowlands) and mitochondrial introgression among lowland strains may indicate fundamental differences in mating strategies between populations. Finally, accelerated parasite dissemination between densely populated, highland areas, compared to uninhabited lowland foci, likely reflects passive, long‐range anthroponotic dispersal. The impact of humans on the risk of epizootic Chagas disease transmission in Bolivia is discussed.

“…Triatomines were sought within a 800m radius of the infested DU using 100 Noireau et al 16 traps placed in tree trunks, rock crevices, birds' nests and animal burrows. The traps were left in place for approximately 14h (19:00 to 09:00h).…”

“…The use of traps has been an alternative method for triatomine capture, contributing to knowledge of species distribution and their population dynamics 3 . Among the trap designs commonly used in field research are those that use illumination sources or live-baits as an insect attractant [4][5][6] .…”

Revista da Sociedade Brasileira de Medicina Tropical 44(6):774-776, nov-dez, 2011Capture of Triatoma arthurneivai (Hemiptera: Reduviidae) using a new luminous trap in Southeast Brazil ABSTRACTIntroduction: Triatomine bug captures in the wild are laborious and timeconsuming. Some traps may assist in this task. We report a new trap design and the capture of a specimen of a triatomine rarely found. Methods: Two luminous traps were installed in the city of Diamantina, State of Minas Gerais, and surveyed weekly for a year. Results: A Triatoma arthurneivai female and other triatomine bugs were caught. Conclusions: A new trap design may be used in triatomine bugs field captures, mainly in low density areas. We assume the center of endemism of Triatoma arthurneivai is the Espinhaço Mountain range.
