This report confirms a recent outbreak of a Leucocytozoon caulleryi infection in a commercial broiler breeder flock in South Korea. Seven, 18-day-old broiler breeders (Gallus gallus) were necropsied following a history of depression, sudden death, and subcutaneous hemorrhages. On necropsy, subcutaneous hemorrhages were identified in the wings and legs, pectoral and thigh muscles, thymus, epicardium, pancreas, and kidneys. On histopathology, there were numerous schizonts and merozoits of a Leucocytozoon sp. noted in the heart, spleen, liver, kidneys, thymus, and bursa of Fabricius. Molecular analysis of the mitochondrial cytochrome oxidase b confirmed that the causative agent was Leucocytozoon caulleryi. Although L. caulleryi was diagnosed previously in South Korea, there had been no reports of L. caulleryi over the past several decades.
本报告证实韩国一个商业性肉种鸡群近期爆发了卡氏住白细胞虫感染。7只18日龄肉种鸡（原鸡）在出现精神沉郁、突然死亡和皮下出血病史后进行了剖检。剖检时，在翅膀、腿部、胸肌和大腿肌肉、胸腺、心外膜、胰腺和肾脏发现皮下出血。组织病理学检查显示，在心脏、脾脏、肝脏、肾脏、胸腺和法氏囊中发现了大量卡氏住白细胞虫的裂殖体和裂殖子。线粒体细胞色素氧化酶b的分子分析证实病原体为卡氏住白细胞虫。虽然韩国此前曾诊断出卡氏住白细胞虫，但在过去几十年中一直没有卡氏住白细胞虫的报告。
