Objectives Plasmodium vivax malaria was thought to be rare in Africans who lack the Duffy
blood group antigen expression. However, recent studies indicate that P. vivax can infect …

Plasmodium vivax malaria was thought to be rare in Africa, but an increasing number of P.
vivax cases reported across Africa and in Duffy-negative individuals challenges this dogma …

Background Plasmodium vivax infection is known to be rare in West/Central Africa, the most
accepted explanation being the lack of expression of erythroid Duffy antigen in the local …

Background Recent studies from different malaria-endemic regions including western Africa
have now shown that Plasmodium vivax can infect red blood cells (RBCs) and cause clinical …

Background The increase in detections of Plasmodium vivax infection in Duffy-negative
individuals in Africa has challenged the dogma establishing the unique P. vivax Duffy …

Background Due to the recently observed rise in Plasmodium vivax incidence in Sudan and
reported transmission in Duffy-negative individuals; we aimed to assess the possibility of P …

P. malariae and P. ovale with and without P. falciparum, 4-8 cases of P. vivax have been
thought to be absent in sSA due to the erythrocyte silent Duffy-negative phenotype across a …

The understanding that red blood cells (RBCs) lacking the Duffy receptor are resistant to
blood stage infection by Plasmodium vivax has provided the conceptual path for productive …

Malaria therapy, experimental, and epidemiological studies have shown that erythrocyte
Duffy blood group-negative people, largely of African ancestry, are resistant to erythrocyte …

Abstract Background Malaria in sub-Saharan Africa (sSA) is thought to be mostly caused by
Plasmodium falciparum. Recently, growing reports of cases due to Plasmodium ovale …
