Estudos sôbre reservatórios e vetores silvestres do Trypanosoma cruzi: XVII. Contribuição para o estudo dos focos naturais da tripanossomose americana, com especial referência à região nordeste do Estado de São Paulo, Brasil

Abstract: A tripanossom ose am ericana, segundo tudo indica, era, prim itivam ente, um a enzootia, afetan d o exclusivam ente anim ais silvestres e sendo tran sm itid a por tria to m íneos de hábitos silvestres. Em algum as áreas do C ontinente A m ericano esta situ a ção ain da persiste. Em outras, porém , o p arasita foi tran spo rtad o p a ra nichos a r tificiais e passou a in fectar o hom em e os anim ais dom ésticos suscetíveis, em p a rti cular o cão e o gato, e a ser transm itido, agora, por triatom íneos dom ici… Show more

“…The evidence for dogs is consistent with observations elsewhere in Argentina (Wisnivesky-Colli et al 1982) and Brazil (Barretto, 1968) but not in Chile (Schenone et al 1985). In our study, the infective indices for cats showed large variations between surveys and households within a given survey.…”

“…Forattini et al (11) found P. megistus foci in hollow trees inhabited by bats, rodents, birds and, mainly, opossums. In artificial ecotopes, P. megistus feeds on humans, domestic animals (especially dogs and cats), commensal mammals (rats), synanthropic mammals (bats and possums), and birds (20) (21) , which results in high infection rates and is also an important link in the domestic transmission cycle of T. cruzi (13) .…”

“…In the early 1960s, it was commonly assumed that only some kissing-bug species were able to transmit parasites across certain habitats and host-species (Barretto et al 1966, Barretto 1968. This perception was reinforced by the association of some hosts with T. cruzi discrete typing units (Zingales et al 2009) and the untested assumption that these patterns are shaped by feeding preferences, which in some cases are assumed to be genetically determined due to fitness differences associated with feeding sources (Piesman et al 1983, Acuña-Retamar et al 2009).…”

“…Ecologically based categories for peridomEcologically based categories for peridomiciliary habitat classification are also necessary because, for some kissing-bug species, the peridomicile could be considered sylvatic because species are not colonizing new habitats; however, humans are becoming part of the kissing-bug species natural habitat. In the early 1960s, it was commonly assumed that only some kissing-bug species were able to transmit parasites across certain habitats and host-species (Barretto et al 1966, Barretto 1968.
