title: Serum antibodies to papova viruses (BK and SV 40) in subjects from the area with Balkan endemic nephropathy.
abstract: The presence of antibodies to BK virus and SV40 was investigated in 63 patients with Balkan endemic nephropathy (BEN) and in 83 apparently healthy subjects from the endemic area. Serum antibodies to BK virus were detected in 95.2% of the former and in 74.7% of the latter, high antibody levels being prevalent in the age groups 41-60 years. Antibodies to SV40 were absent in the BEN patients and their frequency in the healthy subjects (27.7%) was much lower than that previously recorded in healthy persons from other zones of Romania (40%). The results obtained plead for a prevalence of BK virus infection in the endemic area with BEN.
