Efficacy of magnetic capture in comparison with conventional DNA isolation in a survey of Toxoplasma gondii in wild house mice

Popis výsledku v původním jazyce

Toxoplasma gondii is a zoonotic parasite with a world-wide distribution. House mice (Mus musculus) play an important role as a reservoir host in the parasite life cycle. However, their detection in mouse brain is limited because the host potentially harbours only a few tissue cysts. In order to improve the diagnosis, we tested a novel protocol for T. gondii detection in mice and compared this technique to a standard PCR-based protocol using a commercial kit for DNA isolation. Efficacy of magnetic capture for isolation of T. gondii DNA from whole host brains was tested in brain samples of laboratory mice spiked with 1 up to 104 tachyzoites. Real-time PCR revealed that even 1-5 tachyzoites can be detected after magnetic capture. Also this method is suitable to quantify parasite numbers in mouse brains with more than 10 tachyzoite equivalents. To assess the two techniques in wild mice, we employed a dataset consisting of 243 individuals. The prevalence of T. gondii detected by magnetic ca
