Study on Human Cytomegalovirus(HCMV)Infection in the Blood Donors

HCMVs in blood leukocytes and in serum from the same blood donor were examined by polymerase chain reaction (PCR) and DNA hybridization technique. In the mean time, HCMV IgM and HCMV IgG in the serum were examined by ELISA. Two hundred blood leukocyte samples and 200 serum samples were examined in a successive two years period. HCMV positive rates for the blood leukocytes by PCR in the different years were 63% and 70% while the positive rates by DNA hybridization were 42% and 50%, respectively. HCMV postive rates for the serum by PCR in the different years were 49% and 53% while the positive rates by DNA hybridization were 33% and 39%, respectively. A 5% HCMV IgM positive rate was found in the two years while 54% and 58% HCMV IgG positive rates were found in the two different years.
