Abstract:
This is a prospective and analytical study, aimed to determine the frequency of ABO,
Rh antigen, and phenotypes, among Danagla Sudanese tribe. Also the study aimed at
establishe ABO, Rh 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 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 using the slide agglutination techniques, and twenty samples
were tested by 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 ( 50% ) , followed by group A ( 32%), group B was found ( 14% ) and least
common was group AB ( 4%).
The e, c, and the D antigens were the commonest alleles detected with frequencies of
99%, 91% and 91% respectively. The C and the E antigens were the least frequent with
52% and 2% 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.
