Abstract The seroprevalence of Sarcocystis spp. and Toxoplasma gondii was researched in swine raised in Santa Maria, RS, Brazil. Serum samples from 84 pigs from 31 farms were tested using indirect immunofluorescence assay (IFA) for both agents. Additionally, 53 samples of pork sausages and tissues destin...

Abstract This study aimed to identify members of the Sarcocystidae family in naturally infected wild birds at a rescue center in the state of Minas Gerais, southeastern Brazil. The heart and brain of 44 wild birds were evaluated by bioassay in mice to detect T. gondii, and extracted DNA was used for nest...

Abstract The aim of this study was to detect Toxoplasma gondii DNA in oysters (Crassostrea spp.) sold on seven beaches in the State of Pará, Brazil. According to the National Program for Hygiene and Sanitary Control of Bivalve Mollusks, 100 g of the edible part of mollusks is required to analyze contami...
Abstract Molecular methods such as Copro-PCR stand out in the diagnosis of T. gondii, because they are highly sensitive and specific, and can distinguish T. gondii from other morphologically similar coccids. The purpose was the detection of Toxoplasma gondii copro-prevalence by polymerase chain reaction ...

Abstract The aim of this study was to evaluate the genotypic characteristics of Toxoplasma gondii isolated from free-range chickens in the metropolitan area of Goiânia, Goiás, in Brazil's central-west region. The seroprevalence rate was found to be 96%, according to an indirect hemagglutination assay. ...
Abstract Toxoplasmosis occurs worldwide causing economic losses to the animal production and problems to the public health. The study aimed to detect Toxoplasma gondii and Sarcocystis spp.in 141 meat products from commercial meat cuts of pork, beef, and kibbeh sold in commercial markets from Botucatu, SP...
Abstract Felines are definitive hosts of Toxoplasma gondii and can shed oocysts in their feces, contaminating the environment. Sporulated oocysts are highly resistant to the environment and have higher infectivity, which are attributed to many toxoplasmosis outbreaks. The aim of the present study was to ...

Resumen Introducción. La infección por Toxoplasma gondii puede presentarse en los humanos con un amplio rango de manifestaciones que van desde el estado asintomático hasta la enfermedad grave, según el estado inmunológico del individuo. Los mecanismos de transmisión incluyen la transfusión sangu�...

Abstract Toxoplasma gondii and Neospora caninum are closely related coccidian parasites (phylum Apicomplexa). This is the first study from urban synanthropic rodent species that involved serological and molecular diagnosis of T. gondii and N. caninum infection, and genotyping of T. gondii in Argentina. A...

Abstract Recent genetic population studies on Toxoplasma gondii in Brazil have shown large genetic variability. The objective of the present study was to isolate and genotypically characterize T. gondii from free-ranging and captive wild mammals and birds in Pernambuco state, Brazil. Fragments of heart,...
