Resumen:
The eco-epidemiology of the domestic transmission of Trypanosomacruzi in the humid Chaco region has seldom been investigated. We assessed thehousehold distribution of bug, dog and cat infection between local ethnic groups(Tobas and Creoles) to investigate differences in transmission risks between them;tested the role of domestic dogs and cats as reservoir hosts, and identifiedtransmission risk factors.Methodology/Principal Findings: We conducted a cross-sectional survey of houseinfestation with Triatoma infestans and T. cruzi infection in bugs, dogs and cats in awell-defined rural area in northeastern Argentina including 323 households. Buginfection prevalence among 1,869 bugs examined was highest in domiciles (43%) andin storerooms or kitchens (24%), and was marginal elsewhere (
