The Resistance Factor to Plasmodium vivax in Blacks: The Duffy-Blood-Group Genotype,FyFy
Abstract
Duffy-blood-group-negative human erythrocytes, FyFy, are resistant to invasion in vitro by Plasmodium knowlesi. The FyFy genotype is found predominantly in African and American blacks, who are the only groups completely resistant to infection by P. vivax. To determine if the FyFy genotype is the vivax resistance factor, we performed blood typing on 11 black and six white volunteers who had been exposed to the bites of P. vivax-infected mosquitoes. Only the five FyFy blacks were resistant to erythrocytic infection; the remaining six blacks and all whites had the Duffy-positive determinants (Fya or Fyb or both) and had contracted malaria. We conclude that Duffy determinants (Fya or Fyb or both) on the erythrocyte surface are required for invasion of erythrocytes by vivax merozoites.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
