The potential contamination of Toxoplasma gondii and Neospora caninum oocysts in the human environment is a concern from the public health viewpoint. However, estimation of their seroprevalences in humans cannot be performed in a manner that distinguishes between oocysts and tissue cysts as a source of infection. Rabbits are considered popular pet animals in Japan that can acquire natural infections by the aforementioned parasites only through the ingestion of oocysts. Therefore, this study was conducted to estimate the seroprevalences of T. gondii and N. caninum in pet rabbits in Japan as an indicator of the possible oocyst contamination in the environment surrounding human beings. Serum samples of 337 rabbits were examined by different serological...

Toxoplasma gondii microneme protein 2 (TgMIC2), an apically stored adhesin, was shown to be a key participant involved in the initial attachment and invasion to a host cell. In this study, we had established the clonal line of T. gondii tachyzoites which over-expressed TgMIC2 using the tetracycline repressor (TetR)-based inducible gene expression system. The TgMIC2 over-expression significantly reduced tachyzoite propagation in vitro (p &lt; 0.002) and significantly reduced the parasite virulence in mice (p = 0.002). The over-expression of exogenous TgMIC2 caused the increase of mRNA expression level of endogenous TgMIC2. Wild type parasites mainly expressed TgMIC2115 protein, the microneme store and the surface form of TgMIC2. Over-expression of TgMIC2...
