Abstract:
This study was performed in Elbagara ethnic group in the period
between 15/5/2005-15/9/2005. One hundred samples were collected in
EDTA containers to determine the frequencies of ABO and Rhesus
phenotypes and Rhesus gene complexes. Blood samples wee tested by the
slide method, tube method, and ID-card method. The results were
analyzed using the SPSS software program.
In the ABO blood group system the highest frequency was group O
(50%), then group A (26%), followed by group B (20%), and group AB
(4%).
The most frequently occurring antigens of the Rhesus blood group
system were found to be c and e (100%), followed by D (90%), C (31%),
and finally E (15%).
The most frequently phenotype in the Rhesus system was found to
be cDe (48%), followed by CcDe (27%), cDEe (12%), cde (9%), CcDEe
(3%), and Ccde (1%) respectively.
Thirty samples were tested by both the slide and ID-card technique
to make a comparison between the two methods and the same results
were obtained.
The conclusion: Rh-E negative antigen was detected in 85% of
Bagara individuals, Rh-C negative antigen in 69%, Rh-D negative in
10%.
The recommendation: Future studies should be done using a larger
number of samples on other tribes in Sudan to determine the most
common Sudanese genotypes.
