Abstract Dogs are hosts of the protozoans Toxoplasma gondii, which causes an important public health disease, and Neospora caninum. Studies that have evaluated toxoplasmosis and neosporosis for prolonged periods in dog populations are rare. We analyzed infection by both parasites in a domestic dog popula...

Abstract More than 1.450 marine fish species are commercialized as ornamental fish and approximately 90% of these are wild-caught. Rainford's butterflyfish, Chaetodon rainfordi (McCulloch, 1923), is endemic to the western Pacific. This fish species belongs to one of the main ornamental fish families impo...
Abstract Dioctophymosis is caused by Dioctophyme renale, a nematode that usually affects the right kidney of carnivores. The aim of this study was to report on a case of a dog with progressive weight loss and swollen abdomen that was diagnosed as presenting dioctophymosis. The patient underwent surgical ...
Abstract Haemoproteus spp. are protozoan parasites found in birds around the world. These parasites are identified through the morphology of gametocytes, phylogenetic analysis based on the mitochondrial cytb gene, and the parasite's geographic distribution. The absence of erythrocytic merogony, high intr...

Abstract The objective of this study was to investigate the frequency of antibodies to Toxoplasma gondii present in wild mammals that were trap captured in forest fragments in the State of Bahia, northeastern Brazil. A total of 368 individuals (246 rodents, 104 marsupials and 18 bats) were captured using...
Abstract The genus Cotylophoron belongs to the Paramphistomidae family and its definitive hosts are ruminants in general. This work describes the presence of a new species of the gender, a parasite in the rumen and reticulum of Bubalus bubalis, on Marajó Island in the Eastern Brazilian Amazon, using of ...
Abstract Dermacentor nitens is a one-host tick that uses domestic equids as main hosts. Herein, the nonparasitic phase of D. nitens was evaluated under field conditions in Pirassununga, São Paulo state, Southeastern Brazil. By exposing engorged females of D. nitens to field conditions (grass plots) for ...
