O objetivo desse trabalho foi avaliar a ocorrência dos principais parasitos gastrintestinais que acometem caprinos adultos e jovens do município de Quixadá-Ceará durante a época seca e chuvosa, além de identificar e quantificar as espécies de Eimeria presentes no rebanho. Foram utilizados 654 anim...
Considerando a possibilidade de erros na identificação das lesões e a necessidade de melhorar o diagnóstico, o objetivo desse trabalho foi caracterizar macroscopicamente e microscopicamente as principais lesões parasitárias observadas em ovinos na linha de abate. Os materiais foram colhidos durante...
Abstract INTRODUCTION: Leishmania species cause skin, mucosal, and disseminated lesions. We studied the effects of three Leishmania species on ileal morphology in mice. METHODS: BALB/c mice were intraperitoneally inoculated with Leishmania (Leishmania) amazonensis, Leishmania (Viannia) braziliensis, a...
Abstract INTRODUCTION: We evaluated IL-10, IL-2 and regulatory T cells (Treg), in response to ovalbumin (OA), in offspring from schistosomotic mouse mothers. METHODS: We used animals born (BIM) or suckled (SIM) from infected mothers; and mice born/suckled from infected (BSIM) or non-infected mothers (...
Abstract INTRODUCTION The National Park of Serra das Confusões (NPSC) is a protected area of natural landscape located in Southern Piauí, Brazil, and it is considered as one of the largest and most important protected areas in the Caatinga biome. METHODS The natural occurrences of trypanosomatids f...

Abstract INTRODUCTION: The detection of Trypanosoma cruzi in tissue samples is important in many situations, such as testing of the reactivation of the infection. The detection of T. cruzi nests in endomyocardial biopsies (EMB) may be useful to evaluate graft rejection. Given their scarcity, such nests...

Abstract INTRODUCTION: Strongyloides stercoralis is an intestinal parasitic nematode that causes hyperinfection and/or a dissemination syndrome in hosts, which is often difficult to diagnose. This study aims to compare the diagnostic efficacy of four conventional methods used to diagnose strongyloidiasi...
ABSTRACT BACKGROUND: Enteral parasitic diseases are a public health problem in nations with low economic development and in settings with poor sanitation. Amebiasis is the second most frequent form of parasitosis, with a high burden of disease. Knowledge of the prevalence of enteroparasitoses in a give...
