rROP2 from Toxoplasma gondii as a potential vaccine against oocyst shedding in domestic cats

Abstract The aim of the present study was to evaluate oocyst shedding in cats immunized by nasal route with T. gondii proteins ROP2. Twelve short hair cats (Felis catus) were divided in three groups G1, G2 and G3 (n=4). Animals from G1 received 100 μg of rROP2 proteins plus 20 μg of Quil-A, G2 ...

Decay accelerating factor (DAF) as the host antigen with protective activity to complement killing of schistosomula
