Polymorphisms in the Pfcrt, Pfmdr1, and Pfk13 genes of Plasmodium falciparum isolates from southern Brazzaville, Republic of Congo.

ABSTRACT: This study aimed to analyze polymorphisms in Pfcrt, Pfmdr1, and Pfk13 genes' markers of resistance to Artemisinin-based combination therapy (ACT), in Plasmodium falciparum isolates from southern Brazzaville, 15 years after the adoption of ACT in the Republic of Congo. A total of 369 microscopy-confirmed malaria-infected individuals were enrolled from March to October 2021 in the community and in health facilities during a cross-sectional study. The K76T mutation in the Pfcrt gene, N86Y and Y184F mutations in the Pfmdr1 gene were investigated using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) while the codons region (1005-1300) of the Pfmdr1gene, and Pfk13 gene were sequenced. The prevalences of K76T, N86Y, Y184F mutations were 26.0%, 6.8%, and 27.7%, re
