The prevalence of infections with three feline retroviruses (feline immunodeficiency virus (FIV), feline leukemia virus (FeLV) and feline syncytial virus (FSV)) was examined in northern Vietnam in 1997. We collected a total of 77 blood samples from 69 domestic and 8 leopard cats, and examined the presence of anti-FIV and FSV antibodies and FeLV p27 antigen in the plasma samples by the indirect immunofluorescence and/or two commercial kits. None of the samples was positive for FIV and FeLV. The overall positive rate of FSV was 31 % and the positive rates among the domestic and leopard cats were 29 and 50%, respectively. We isolated FSV from peripheral blood mononuclear cells of 6 domestic and one leopard cats.
