The Epstein-Barr virus (EBV) is a ubiquitous Herpes virus which causes infectious mononucleosis and is associated with such different neoplasms as Burkitt's lymphoma and nasopharyngeal carcinoma. EBV latently infects its target cells; nevertheless, evidence of viral replication in NPC tumours has be

A salt-dependent DNA polymerase activity was demonstrated in the culture of an EBV-producing, lymphoblastoid cell line (NPC-204 cells) treated with 5-iodo-2'-deoxyuridine (IUdR). There was a high frequency of levels of antibody to this enzyme in sera of patients with nasopharyngeal carcinoma (NPC).
## RESULTS. In specimens from 107 patients with NPC, EBV was detected by PCR in 2 Department of Pathology, the Johns Hopkins 97 cases (90.7%) and by EBER in situ hybridization in 105 cases (98.1%). In speci-
IgG and IgA antibodies to Epstein-Barr virus (EBV) membrane antigen (MA) were detected in sera from 96 NPC patients and normal individuals by the indirect immunofluorescence test. For MA/IgG antibody, 100% of NPC patients were positive with a GMT of 1:439.7 and 97.9% of normal individuals were posit
