Detection of latent human cytomegalovirus in organ tissue and the correlation with serological status.
The presence of human cytomegalovirus (HCMV) genome in spleen tissue was studied by using DNA hybridization techniques in seropositive and seronegative organ donors without clinical or laboratory confirmed HCMV infection. The serum samples of these patients were screened by latex agglutination test (LA) and enzyme linked immuno sorbent assay (ELISA) for the presence of HCMV antibodies, and confirmed by immunoblotting technique (IB). For the detection of HCMV sequences in spleen tissue dot blot DNA hybridization (DBH) using probes derived from immediate-early and late regions (ES and BH fragment respectively) of the HCMV genome were used. Samples positive in DBH were further tested by in situ DNA hybridization (ISH) using the ES probe. The number of spleen tissue specimens positive for HCMV nucleic acids indicated that HCMV may be present in human beings, even without serological evidence.
