Levels of anti-EPO antibody in the semi-immune mice at infection and recovery. These are anti-EPO antibody level at infection and recovered (R). Blood was harvested for serum at minimum Hb (i.e. maximum Hb reduction, at infection) and recovery (when parasitaemia is cleared). Means of Anti-EPO Ab at infection and recovery differed, p = 0.045 and 0.0004 respectively. *Balb/c values significantly higher when compared with B6 (p < 0.05). **Balb/c values at recovery different from B6 and NZW (p < 0.05). ^#Significantly lower when compared with the others at infection and recovery (p < 0.0001). Values at infection and recovered differed (p = 0.0008). Recovery refers to time at which mice has been rested for two weeks after treatment with chloroquine/pyrimethamine for 6 days or until parasitaemia is zero. Values are means and errors bars being standard deviation (SD). Data was analysed by ANOVA after they were log₁₀ transformed. n refers to number of samples. These are pooled data of two separate experiments. Un Control means uninfected control (consist of 2 mice per strain, giving a total of 8 mice).
