Abstract:
This prospective and analytical study, aimed to determine the
frequency of ABO, Rh (D) and Kell ( Kpa and Kpb ) antigens , and
phenotypes, among ElNuba Sudanese tribe. Also aimed at established
ABO, Rh (D) and Kell ( Kpa and Kpb ) blood group baseline data for this
Sudanese tribe to determine the interaction between this tribe and other
Sudanese tribes which will be useful in the blood transfusion, The study
was conducted during three months (April to June, 2007), Following
informed consent, a total of hundred venous blood samples were
collected from unrelated individual into 2.5 ml EDTA containers. All
samples were tested for ABO, Rh (D) and Kell (Kpa and Kpb) by using
immune-diffusion gel technique for Kell, and, slide method for ABO and
Rh (D).The antigens and phenotypes were determined. Similarities
between this tribe and other Sudanese tribes and with other countries
were calculated using Jaccard's coefficient of similarities.
The results obtained showed that, The O group was most common
frequently occurred ( 56% ) , followed by group A ( 28%) group B was
found ( 14% ) and least common was group AB ( 3%) .The frequency of
the Rh ( D) was most common frequently occurred ( 95% ) .the
frequency Kpa antigen was least frequently ( 0.00% ),while Kpb was
highest common frequently ( 100% ) , The phenotype Kp(a+b-) was
not found in this study. There was a marked similarities between the
Sudanese tribes that lived in same geographical area this could be due to
intermarriage , while the difference that seen in some tribes could be most
probably due to the wandering nature of these tribes.
