Abstract:
This prospective and analytical study, aimed to determine the frequency
of ABO, Rh antigen, and phenotypes, among Halanga Sudanese Ethnic
group. Also aims to establish ABO, Rh blood group baseline data for this
Sudanese tribe to determine the similarity between this tribe and other
Sudanese tribes which will be useful in the blood transfusion.
The study was conducted during three months (April to July, 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 and for common Rhesus antigens by using the
slide agglutination techniques, and immune-diffusion gel technique. 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 (47% ) , followed by group A ( 28%), group B was
found ( 22% ) and least common was group AB ( 3%).
The e, c, and the D antigens were the commonest alleles detected with
frequencies of 96%, 91% and 82%, respectively. The C and the E antigens
were the least frequent with 40% and 15% frequencies respectively.
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.
