Abstract:
This is a descriptive, prospective and analytical study that aimed to
determine the frequencies of ABO, A-subgroup and Rhesus blood group
antigens and phenotypes among Al-Hassania Sudanese ethnic group in
Kosty city in White Nile state.
This study was conducted during the period of three months (January-
March 2010), following informed consent, A total of 100 venous blood
samples were collected in 2.5 ml EDTA blood container from unrelated
individuals. The samples were tested for ABO blood group antigens and
A-subgroup by direct slide method, while for the Rhesus blood group
antigens the samples were tested by tube method. Du technique was
performed for each Rh (D) negative sample.
The results obtained from this study showed that in ABO blood group
system the A antigen was the commonest antigen with the frequency of
(42%), followed by O antigen (33%), B antigen (19%) and the least
common was AB antigen (6%0.
In A-subgroup A1 antigen had the highest frequency (41|%),
followed by A1B (5%), while both A2 and A2B were the rarest with
same frequency (1%).
In Rhesus blood group antigens the e and c antigens were the
commonest antigens detected with the same frequency for both (100%),
followed by D antigen (97%), C (79%) and E antigen which was the least
frequent with a frequency of (46%).
The results of this study were compared with the results of other
Sudanese ethnic groups in the same systems and were found that there
were similarity in some ABO blood group antigens, subgroup and Rhesus
antigens with the Halaween, Arakieen, Al-Shaigia, Gaaleen and AL-
Shokria Sudanese ethnic groups, and there were differences with the
Meseria, Al-Noba, Al-Danagla, Al-Mahas and Al-Hwsa Sudanese ethnic
groups.
We conclude that the similarity between Sudanese tribes that living in
one area resulting from interaction and intermarriage between them,
while that there were differences between the tribes that living in
different geographical area.
