Taking together msp-1 and msp-2, our findings are in contrast to those reported in previous studies in Brazzaville and other countries such as Gabon, Benin, Ghana, and Ethiopia where K1 for msp-1 and 3D7 for msp-2 were predominantly found in isolates from uncomplicated malaria [17, 25, 33-36]. This evidence concerns the gene ATAD1 and malaria.
