Consistent with the high homology (>70%) between the promiscuous T cell epitopes and the MSP19 fragment included in PvRMC-MSP1 and the simian malaria species P. coatneyi and P. cynomolgi, we observed that antibodies induced by PvRMC-MSP1 were able to recognize P. coatneyi blood stage parasites by IFA. The gene discussed is ATAD1; the disease is malaria.
