title: Reaginic and non-reaginic antibodies against mammalian danders.
abstract: Solid phase enzyme immunoassay (EIA) and passive haemagglutination techniques were used to study the occurrence of IgG-type antibodies against feline and bovine epithelial extracts among RAST-positive patients, senior veterinary students, cat fanciers (representing exposed subjects) and healthy controls. In most groups both techniques exhibited equal sensitivity being positive in about half of the RAST-positive cases. The levels of both EIA-reactive IgG-class and IgA-class antibodies were increased in most of the sera (greater than mean + 2 s.d. of controls), while only a few sera showed increased IgM values.
