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.
采用间接免疫荧光技术检测了102名信鸽饲养者血清中针对信鸽肠道内抗原的循环IgG抗体。15名对吸入激发试验呈阳性反应的有症状饲养者体内存在针对黏膜组织的抗体。大多数无症状饲养者表现为肠道排泄物荧光阳性并伴有黏膜组织微弱荧光，或者血清中未检测到抗体。通过间接免疫荧光法发现的抗体比琼脂免疫沉淀反应更常见。
