Detection of Toxoplasma gondii in the milk of experimentally infected Wistar female rats

Detection ofToxoplasma gondiiin the milk of naturally infected goats in the Northeast of Brazil

“…() reported the elimination of the parasite in milk and stated that it was infectious to inoculated mice. More recently, Costa and Langoni () confirmed the presence of tachyzoites in the milk secreted from experimentally infected rats, as well as the seroconversion of offspring after breastfeeding. The infection of kids through ingesting milk from goats that have been naturally infected should be investigated further.…”

“…Tachyzoites have already been identified and isolated in milk secreted from goats. These studies have shown that in certain regions of the world, milk is a significant source of T. gondii infection in humans (Chiari and Neves, ; Skinner et al., ; Vitor et al., ; Dubey et al., ; Powell et al., ; Veronesi, ; Costa and Langoni, ).…”

Cats and Animals Product as a Source of Transmission Toxoplasmosis

“…Evidence that Tachyzoites Toxoplasma gondii has been found in milk and its ability in transmition infection has been documented by several researchers. Powell et al, Costa and Langoni, respectively reported, that cats and rat infected with T. gondii, their milk contained viable and transmitable T. gondii [29,30]. Conducted research and reported that T. gondii lives can be excreted in goat's milk and can survive in fresh cheese, while Bezerra et al and Ossani, et al found, respectively, 6.05% and 30.95% of the milk samples of naturally infected goats and dairy ewes were positive with T. gondii [20,[31][32][33][34].…”

Concordância na detecção de anticorpos anti-Toxoplasma gondii e anti-Neospora caninum no sangue e no leite bovino pela reação de imunofluorescência indireta

“…Em toxoplasmose, os relatos de detecção de anticorpos no leite são limitados, sendo relatados em ratas, cabras e ovelhas (VITOR et al, 1991;COSTA & LANGONI, 2010). Em bovinos, no Brasil, não existem estudos que associem a ocorrência de anticorpos no soro sanguíneo e no leite para T. gondii.…”

“…Em bovinos, no Brasil, não existem estudos que associem a ocorrência de anticorpos no soro sanguíneo e no leite para T. gondii. Os testes para detectar anticorpos anti-T. gondii e N. caninum no leite poderiam ser mais utilizados, porém, as informações a respeito do método da RIFI para este tipo de análise em bovinos são limitadas até o presente (COSTA & LANGONI, 2010;CAMILLO et al, 2011). O objetivo deste estudo foi avaliar a aplicabilidade da pesquisa de anticorpos anti-Toxoplasma gondii e anti-Neospora caninum em amostras de leite bovino pela reação de imunofl uorescência indireta (RIFI) e sua concordância com a detecção desses anticorpos em amostras de soro sanguíneo, simultaneamente coletadas das mesmas vacas.…”
