Intestinal infection of many host species with Lawsonia intracellularis are widely reported. Analyses of infections among carnivorous falcons have not previously been reported. Fifty juvenile captive falcons (Falco spp.) with or without Lawsonia infection were investigated in the United Arab Emirates, including clinical laboratory methods. Fresh intestinal biopsy samples were analysed by microbiological techniques for Lawsonia and other bacteria and by standard parasitological and pathological methods. Lawsonia intracellularis infection was diagnosed by microbiological examination and qPCR in 10 of 50 juvenile falcons at case examination. Seven of these 10 falcons were of normal clinical appearance, and the other three had other contributing factors to ill-thrift. A range of other conditions were noted in 40 case control falcons. This first report of Lawsonia infection in falcons suggests that the agent may have a limited contribution to clinical disease in these birds, including ill-thrift syndromes. This lack of clinical disease association mimics that noted among Lawsonia infections recorded in other avian families.
已广泛报道多种宿主物种的肠内感染细胞内罗森菌。以前没有报道过对肉食性猛禽的感染分析。在阿拉伯联合酋长国，对 50 只有或没有细胞内罗森菌感染的圈养幼隼进行了调查，包括临床实验室方法。通过微生物技术对新鲜肠活检样本进行了细胞内罗森菌和其他细菌的分析，以及标准寄生虫学和病理学方法。在 50 只幼隼中，通过微生物检查和 qPCR 在 10 只幼隼中诊断出细胞内罗森菌感染。这 10 只幼隼中有 7 只临床症状正常，其他 3 只有其他导致身体不适的因素。在 40 只对照幼隼中注意到了一系列其他病症。这是首次在隼中报告细胞内罗森菌感染，这表明该病原体可能对这些鸟类的临床疾病，包括身体不适综合征，只有有限的贡献。这种缺乏临床疾病关联类似于在其他鸟类家族中记录的细胞内罗森菌感染所注意到的情况。
