Copy Number Variations of Plasmodium vivax DBP1, EBP/DBP2, and RBP2b in Ethiopians Who Are Duffy Positive and Duffy Negative.

Recent evidence challenges the belief that individuals who are Duffy-negative are resistant to Plasmodium vivax due to lacking the Duffy antigen receptor for chemokines. Erythrocyte-binding protein (EBP/DBP2) has shown moderate binding to Duffy-negative erythrocytes in vitro. Reticulocyte-binding protein 2b (RBP2b) interactions with transferrin receptor 1 suggest involvement in Duffy-negative infections.

Detection of Duffy blood group genotypes and submicroscopic Plasmodium infections using molecular diagnostic assays in febrile malaria patients.

Background: Malaria remains a severe parasitic disease, posing a significant threat to public health and hindering economic development in sub-Saharan Africa. Ethiopia, a malaria endemic country, is facing a resurgence of the disease with a steadily rising incidence. Conventional diagnostic methods, such as microscopy, have become less effective due to low parasite density, particularly among Duffy-negative human populations in Africa.
