Abstract
Using 50 forensic blood samples, the latent membrane protein 2A (LMP-2A) gene of Epstein-Barr virus (EBV) DNA was amplified to find a geographic correlation among the EBV genotypes. EBV DNA was detected in nine samples. From a phylogenetic analysis using 18 reported sequences as a reference, six EBV subtypes (Ia, Ib, Ic IIa, IIb, and IIc) were found. Japanese isolates were included in subtypes Ia or IIa. All the Asian reference isolates, except isolate D6, were included in subtype Ia or IIa. Mediterranean, an Alaskan and other African isolates were included in types Ib, Ic, IIb and IIc. The EBV genotype in the LMP-2A gene was thus demonstrated as being correlated with the host's geographical location. Typing in the EBV-associated nuclear antigen 2 gene was not related to that in the LMP-2A gene. Detection of the EBV genotype in the LMP-2A gene may be useful for determining the geographical origins of unidentified cadavers.
