Bacterial contamination of blood and blood components in three major blood transfusion centers, Accra, Ghana.

Reports from studies conducted in several countries indicate a high incidence of bacterial contamination of donor blood. The prevalence of bacterial contamination of blood and its products in Ghana is not known. This study was conducted to determine the prevalence of bacterial contamination of blood and its products at the three major blood transfusion centers in the Greater Accra Region of Ghana.

Seroprevalence of cytomegalovirus among some voluntary blood donors at the 37 military hospital, accra, ghana.

Summary Background: Cytomegalovirus (CMV) is one of the most significant pathogens infecting immunosuppressed individuals. CMV is transmissible through transfusion of blood components.

Aim: The goal of this study was to determine the seroprevalence of antibodies to CMV among blood donors seen at the 37 Military Hospital Blood Transfusion Unit, (MHBTU) Accra, Ghana.

Seroprevalence of human T-cell lymphotropic virus type I among pregnant women in Accra, Ghana.

Infection with human T-cell lymphotropic virus type I (HTLV-I) occurs mainly in Japan, Central and West Africa and the Caribbean Basin. Although antibody to HTLV-I has been reported among pregnant women in several endemic countries, there is no information regarding the seroprevalence in pregnant Ghanaian women. The reported seroprevalence of HTLV-I among healthy Ghanaian blood donors is between 0.

The presence of an RHD pseudogene containing a 37 base pair duplication and a nonsense mutation in africans with the Rh D-negative blood group phenotype.

Antigens of the Rh blood group system are encoded by 2 homologous genes, RHD and RHCE, that produce 2 red cell membrane proteins. The D-negative phenotype is considered to result, almost invariably, from homozygosity for a complete deletion of RHD. The basis of all PCR tests for predicting fetal D phenotype from DNA obtained from amniocytes or maternal plasma is detection of the presence of RHD.
