It has been shown that many pigeon materials contain one or more of four pigeon proteins—pigeon γ-globulin (PGG), pigeon serum albumin (PSA), pigeon β-globulin (PBG) and a protein cross-reacting immunologically with PGG termed XPGG. It is thought that the ability of seemingly unrelated sources of pigeon material, e.g. pigeon droppings, serum, egg yolk and white to react with sera from cases of pigeon breeders' disease is due to the presence of PGG, PSA, PBG or XPGG in these materials. Only in pigeon droppings were important antigens other than PGG, PSA, PBG and XPGG found and it is possible that pigeon droppings are the only `complete' source of antigens concerned with the disease unless specified conditions arise.
已经表明，许多鸽源材料含有四种鸽蛋白中的一种或多种——鸽γ球蛋白（PGG）、鸽血清白蛋白（PSA）、鸽β球蛋白（PBG）以及一种与PGG发生免疫交叉反应的蛋白，称为XPGG。据认为，看似不相关的鸽源材料，如鸽粪、血清、蛋黄和蛋清，能够与鸽饲养者病患者的血清发生反应，是由于这些材料中存在PGG、PSA、PBG或XPGG。仅在鸽粪中发现了除PGG、PSA、PBG和XPGG之外的重要抗原，并且除非出现特定情况，鸽粪有可能是与该疾病相关的唯一“完整”抗原来源。
