Abstract:
This is a descriptive and cross sectional study which took
place in
Sudan in shendi town . the study aimed to
determine the frequency of –ABO and-Rh blood group
antigens and phenotypes among Aljaaleen tribe .
This study was conducted during the period of six months
between February
and
July 2011 , following informed
consent a total of two hundred venous blood samples were
collected from un related individuals into 2.5 mls EDTA
containers , the red blood cells were tested for –ABO by tube
agglutination techniques and common –Rh antigen by
practice gel immune diffusion and 30% of specimens were
tested by the tube agglutination techniques , the alleles and
frequencies were determined , results were analyzed by SPSS
program and the similarities were detected .
The antigen-O was the most common Ag among the study
group (51) followed by-A (25%)-B (17%) and the least
common was-AB antigen (6%) .
The-e-c and-D antigens were the commonest alleles detected
with frequencies of (98%) (94%) and (91%) respectively , the
–E and-C antigens were the least frequent with
(37%) and
(49%) frequencies respectively.
Similarities between Aljaaleen and some Sudanese
populations and differences with others were noticed. And
this could probably point to a common ancestry in very
ancient days .Some changes could be seen which explained
by wandering nature of some Sudanese tribes .
