Chagas disease in north-west Argentina: Association between trypanosoma cruzi parasitaemia in dogs and cats and infection rates in domestic triatoma infestans
The association between Trypanosoma cruzi parasitaemia in dogs and cats and Tryp. cruzi infection rates in domestic Triatoma infestans was studied in a cross-sectional survey of 31 houses (89%) in the rural villages of Trinidad and Mercedes, north-west Argentina, where no spraying of insecticides ha...
