FIGURE 8.
The sera from Δgra9-vaccinated mice are able to reduce parasite propagation in mice. The sera from PLK:Δgra9-vaccinated mice were administered into 105 PLK parasites infected mice at 0 and 3 day post-infection, survival rates were noted and parasite burdens were determined in peritoneal fluids at day 5 and 7 post-infection to evaluate parasite growth under passive immunization. The four mice for naïve sera as negative control, and five mice for PLK:Δgra9-vaccinated sera as test group. (A) Survival rates (*P < 0.05; Log-rank (Mantel-Cox) test). (B) Parasite burdens (****P < 0.0001; Student’s t-test).
