Distribution of type A and type B EBV in normal individuals and patients with head and neck carcinomas in Taiwan.
The subtypes of Epstein-Barr virus (EBV) according to the EBNA 2 gene were investigated in Taiwan by the polymerase chain reaction (PCR) and by Southern blot hybridization. The materials included 53 nasopharyngeal carcinoma (NPC) biopsies, 49 other head and neck cancers and 32 throat washings of normal individuals. EBV DNA was found in all NPC biopsies, 27 of 49 other head and neck carcinomas and 81% of normal individuals. Type A EBV was the predominant type of EBV in both normal individuals and patients with head and neck carcinomas in Taiwan. Type B EBV or coexistence of the A and B types comprised a small number of samples in this study.
