However, at the late stage of infection the parasites that were not exposed to ATc produced remarkably higher levels of lplA2 mRNA which was not observed in the parasites exposed to ATc (Student’s t-test: clone 21, t(4) = 38.39, P < 0.001; clone 56, t(4) = 92.98, P < 0.001; Fig. 4b). The gene discussed is PLA2G15; the disease is infection.
