Abstract INTRODUCTION: Road-killed wild animals host zoonotic pathogens such as Toxoplasma gondii, offering a new opportunity for the epidemiological study of these infectious organisms. METHODS This investigation aimed to determine the presence of T. gondii and other apicomplexan parasites in tissue ...
Trypanosoma cruzi, um protozoário parasita, é o agente etiológico da doença de Chagas. A infecção chagásica apresenta duas fases: aguda e crônica. Na fase aguda a mortalidade é mais frequente, sendo que o organismo que consegue sobreviver a ela passa para a fase crônica indeterminada. No trato ...
A zoonose causada pelo Toxoplasma gondii é conhecida como toxoplasmose. Possui distribuição geográfica mundial, com alta prevalência sorológica, podendo atingir mais de 60% da população. Os casos de doença clínica não são muito frequentes, porém ainda assim, é uma infecção muito temida du...
Abstract The present study used the indirect fluorescent antibody test (IFAT) to determine the seroprevalence of Sarcocystis neurona, Toxoplasma gondii and Neospora spp., and evaluated the variables associated with these infections among 506 apparently healthy horses, reared in the south of the state of ...

INTRODUCCIÓN: la toxoplasmosis es la enfermedad parasitaria más difundida en el mundo que afecta al hombre, descrita hace poco más de 100 años y producida por Toxoplasma gondii. Una de las formas que el hombre adquiere la enfermedad es a través de la placenta, de órganos trasplantados y por transfu...
Abstract The aim of the present study was to investigate the occurrence of anti-Toxoplasma gondii antibodies and parasite DNA in backyard chickens bred in the metropolitan area of Recife, Brazil. In total, 212 serum samples were collected from 16 properties, and 12 backyard chickens were collected in the...
Abstract Phylogenies within Toxoplasmatinae have been widely investigated with different molecular markers. Here, we studied molecular phylogenies of the Toxoplasmatinae subfamily based on apicoplast and mitochondrial genes. Partial sequences of apicoplast genes coding for caseinolytic protease (clpC) an...
Abstract Capybaras (Hydrochoerus hydrochaeris) are the largest rodents found in South America. The aim of the present study was to investigate the occurrence of anti-Toxoplasma gondii and anti-Neospora caninum antibodies in 170 free-living capybaras in a residential park area in Itu Municipality, São Pa...

Introdução: A água tem sido considerada um importante veículo para a disseminação de surtos de toxoplasmose em vários países. Os oocistos de Toxoplasma gondii podem persistir no ambiente durante longos períodos, sendo altamente resistentes aos vários processos químicos de inativação, inclusi...
Toxoplasma gondii is a cosmopolitan, intracellular, obligatory parasite protozoan of importance to public and animal health. In sheep, this species is a causative agent of reproductive disorders. The main sign produced by T. gondii infection in this species is abortion, which causes economic losses to sh...
