“幼鸽病”是赛鸽爱好者用来描述近年来经常发生的一种疾病，这种疾病会在鸽子出生后的第一年影响鸽子。其特征是作物排空缓慢、反流、腹泻、体重减轻、性能差，偶尔死亡。关于这种综合征的科学信息很少，无法将其与发生在幼鸽中的其他疾病区分开来。在这项研究中，从9个鸽舍中的每一个报告了“幼鸟病”的1只鸟被安乐死的细胞学和死后检查。淋巴网状系统、消化道和呼吸系统的病变是最常见的发现。淋巴网状系统的病变存在于所有检查的鸟类，3只鸟的组织病理学结果与圆环病毒感染一致。原虫，真菌和混合细菌感染的组合与7只鸟和6只鸟肠炎的ingluitis。在5只经聚合酶链反应检测为嗜衣原体阳性的鸡中发现了嗜衣原体炎。虽然“幼鸟病”似乎是一种多因素疾病，但涉及淋巴网状系统、胃肠道和呼吸系统的病变模式是明显的，而其他器官系统的疾病是罕见的。这些研究结果表明，“幼鸟病”可能有一个共同的病因，并提出圆环病毒感染作为一个可能的起始原因，这种综合征在北方爱尔兰的年轻赛鸽。
"Young bird sickness" is a term used by racing pigeon fanciers to describe a condition that has occurred regularly in recent years and affects pigeons (Columba livia domestica) in their first year of life. It is characterized by slow crop emptying, regurgitation, diarrhea, weight loss, poor performance, and occasionally death. Little scientific information is known about this syndrome to differentiate it from other diseases that occur in young pigeons. In this study, 1 bird from each of 9 lofts where "young bird sickness" was reported was euthanatized for cytologic and postmortem examination. Lesions of the lymphoreticular system, alimentary tract, and respiratory system were the most common findings. Lesions of the lymphoreticular system were present in all birds examined, and 3 birds had histopathologic findings consistent with circovirus infection. Combinations of protozoal, fungal, and mixed bacterial infections were associated with ingluvitis in 7 birds and enteritis in 6 birds. Pneumonitis was found in 5 birds that tested positive for Chlamydophila by polymerase chain reaction. Although "young bird sickness" appears to be a multifactorial condition, a pattern of lesions that involved the lymphoreticular, gastrointestinal, and respiratory systems was evident, whereas diseases of other organ systems were uncommon. These findings suggest that "young bird sickness" may have a common etiology, and circovirus infection is proposed as a possible initiating cause of this syndrome in young racing pigeons in Northern Ireland.
