Abstract: Trypanosoma cruzi infection in sylvatic mammals of the quebracho woods of the eastern part of Santiago del Estero province, Argentina, was studied from October 1984 to December 1987. 301 mammals of 20 different species were caught. T. cruzi, characterized biologically and biochemically, was isolated by xenodiagnosis from 23 of 72 (32%) Didelphis albiventris opposums, 2/36 (5.5%) Conepatus chinga skunks, and one ferret (Galictis cuja). 53 opossum refuges were located and triatomine bugs were found in 2 of them:… Show more

“…The predominance of lineage I among isolates from sylvatic habitats is probably due to the role of opossums as the major local sylvatic reservoir host of T. cruzi (Schweigmann et al 1999) and to the absence of T. cruzi infection among armadillos. Opossums have consistently been found infected almost exclusively with lineage I throughout the Chaco region and the Americas (Barnabé et al, 2000;Ceballos et al, 2006;Diosque et al, 2003;Wisnivesky-Colli et al, 1992;Yeo et al, 2005). Armadillos, especially Dasypus novemcinctus, are sylvatic hosts of T. cruzi II in the Paraguayan Chaco (Yeo et al, 2005) but they are very rare in the study area.…”

“…In the late 1980s, when intense domestic transmission of T. cruzi was prevalent and widespread, sylvatic mammals (opossums, ferrets and skunks) were sometimes found infected with TC IId, which also infected domestic dogs and Tr. infestans in Santiago del Estero (Wisnivesky-Colli et al, 1992;De Luca d'Oro et al, 1993). In such an epidemiological context of intense transmission, the observed distribution of lineages was probably a spillover of parasite strains from domestic into sylvatic habitats.…”
