[Use of the real time RT-PCR for immune related gene expression quantitation in experimentally infected Neospora caninum bovine calves].

Neospora caninum is one of the main causes of abortion and natimortality in cattle. Host immune defense is capable to inhibit tachyzoite activity during acute infection, but there is no action against bradyzoites in tissue cysts. Activation and modulation of this response is controlled by cell mediators.
