title: Detection of IgG antibodies against pigeon intestinal mucosa antigens in pigeon breeders' sera using the immunofluorescent technique.
abstract: The serum of 102 pigeon breeders was examined for circulating IgG antibodies against antigens localized in pigeon intestine by the indirect immunofluorescent technique. 15 symptomatic breeders with a positive response to inhalation challenge had antibodies against mucosa tissue. The majority of asymptomatic breeders demonstrated either a fluorescence of intestinal excrements combined with a weak fluorescence of mucosa tissue or had no detectable antibodies in their serum. By the indirect immunofluorescence, antibodies were found more frequently than by immunoprecipitin reactions in agar.
