Open Access Abstract Various genetic and environmental factors appear to be involved in systemic lupus erythematosus SLE . Epstein-Barr virus EBV is among the environmental factors that are suspected of predisposing to SLE based on the characteristics of EBV itself and on sequence homologies between autoantigens and EBV antigens. In addition higher titers of anti-EBV antibodies and increased EBV seroconversion rates have been observed in SLE patients as compared with healthy control individuals. Serologic responses do not directly reflect EBV status within the body. Clarification of the precise status of EBV infection in SLE patients would help to improve our understanding of the role played by EBV in this disease. In the present study we determined EBV types in SLE patients n 66 and normal control individual n 63 by direct PCR analysis of mouthwash samples. .
