BACKGROUND In southeastern Brazil, autochthonous cases of malaria can be found near Atlantic Forest fragments. Because the transmission cycle has not been completely clarified, the behaviour of the possible vectors in those regions must be observed. A study concerning the entomological aspects and natura...

BACKGROUND Trypanosoma cruzi circulates in sylvatic habitats, mainly through blood-feeding triatomines, although other routes also contribute to its dispersion. Sexual transmission of T. cruzi is an understudied topic, especially among wild mammals. Because of the difficulties inherent to field work, exp...
BACKGROUND The northern limits of Trypanosoma cruzi across the territory of the United States remain unknown. The known vectors Triatoma sanguisuga and T. lecticularia find their northernmost limits in Illinois; yet, earlier screenings of those insects did not reveal the presence of the pathogen, which h...

A cisticercose bovina é uma zoonose de distribuição mundial. No Brasil, o controle é realizado através do diagnóstico anatomopatológico durante a inspeção post-mortem nos matadouros. Objetivou-se neste estudo determinar a localização de cisticercos nos tecidos rotineiramente inspecionados e so...
Given the numerous reports of anthelminthic resistance of sheep nematodes to different anthelmintic compounds, this study aimed to evaluate the resistance status of gastrointestinal nematodes from naturally infected sheep to monepantel in the state of Rio Grande do Sul. Four farms that present extensive ...
O carrapato Amblyomma rotundatum é uma espécie partenogenética, encontrada principalmente em anfíbios e répteis silvestres em todos os biomas brasileiros. No presente relato, registra-se a ocorrência de dois machos dessa espécie de ixodídeo encontrados em um jabuti-tinga (Chelonoidis denticulatus...
