Frequency of ABO, A-sub group and Rhesus Blood group systems among Al-messeria Sudanese ethnic group in South Kordofan 2012

Abstract

This is a descriptive, prospective and analytical study that aimed to determine the frequency of ABO, A-sub group and Rhesus blood group antigens and phenotypes among Almesseria ethnic group in south kordofan state. This study was conducted during the period of six month (February – august 2012), following informed consent , a total of 100 venous blood samples were collected in 2.5ml EDTA blood container from un related individuals. The samples were tested for ABO blood group antigens and A-sub group by direct a slide method , while for the Rhesus blood group antigens the sample were tested by tube method. Du technique was performed for each Rh (D) negative sample. The result obtained from this study showed that in ABO blood group system the O antigen was the commonest antigen with the frequency of (45%), followed by A antigen (36%), B antigen (16%) and the least common was AB antigen (3%). In A-sub group A1antigen had the highest frequency (34%), A1B antigen(3) ,A2(2) and A2B is not found. In Rhesus blood group antigens the frequency of c antigen was (99%) which was the highest frequency followed by e antigen (97%) , D antigen (88%), C antigen (34%) and E antigen (21%) which was the lowest frequency. This study concluded that the similarity between Sudanese tribes that living in one area resulting from inter action and intermarriage between them.
