Human peripheral blood lymphocytes from healthy adults, cord blood lymphocytes, and lymphoblastoid cell lines were screened by hybridization for the presence of group C adenovirus DNA sequences. In 13 of 17 peripheral blood lymphocyte samples from adults, 1 of 10 cord blood samples, and seven of seven lymphoblastoid cell lines tested, results were positive for Group C adenovirus DNA (adenovirus 1 [Ad1], Ad2, Ad5, or Ad6). About 1 to 2% of the lymphocytes carried 50 to 100 viral genome copies per positive cell, as estimated by in situ hybridization. Infectious virus representing all members of group C were recovered, but cultivation in the presence of adenovirus antibody did not cure the cells of free viral genomes. Viral DNA was found in B, T, and N cells but only in 1 of 10 cord blood samples. The results suggest that group C adenovirus infections in childhood result in the persistence of the viral genome in circulating lymphocytes.
