title: Widespread occurrence in mammals of antibodies reactive to intracytoplasmic A particles of the mouse mammary tumor virus.
abstract: Serum antibodies reactive to clusters of intracytoplasmic A particles in mouse mammary tumors and leukemia cells by means of an indirect immunofluorescence assay were detected in 11 mammalian species (ranging in frequency from 5.1 to 29.3%). These antibodies could not be found in sera from chicken, ducks and geese. Their presence in so many mammalian species, not only in mammary tumor virus-infected mice, sheds new light on similar antibodies in man detected 10 years ago.
