Two commercial flocks of Chinese partridge experienced increased mortality associated with a wasting disease at 120-day old in June 2006. Postmortem examination of dead chickens consistently showed visceral tissues mainly proventriculus, liver and spleen were diffuse enlargement. Microscopic examination revealed masses of immature lymphocytes with frequent mitotic figures were seen in various tissues including proventriculus, liver, spleen, kidney, heart, lung, thymus and intestine. Reticuloendotheliosis virus (REV) was isolated from each of four blood samples. Viral antigens were observed in cultured CEF (SPF embryos came from the Ji-nan poultry institute) inoculated blood samples via on indirect immunofluorescent assay. Three hundred bp fragments of LTR of REV obtained from liver samples of six chickens by PCR. This disease has not previously been reported in Chinese partridge. Chinese partridge may represent a potential reservoir of infection for other Chinese local chickens.
2006年6月，两个商业饲养的鹧鸪群在120日龄时因一种消瘦病导致死亡率增加。对死亡鸡的尸检始终显示内脏组织（主要是腺胃、肝脏和脾脏）弥漫性肿大。显微镜检查发现，在包括腺胃、肝脏、脾脏、肾脏、心脏、肺、胸腺和肠道在内的各种组织中可见大量带有频繁有丝分裂象的未成熟淋巴细胞。从四份血液样本中均分离出网状内皮组织增生症病毒（REV）。通过间接免疫荧光试验，在接种了血液样本的培养鸡胚成纤维细胞（SPF胚胎来自济南家禽研究所）中观察到病毒抗原。通过PCR从六只鸡的肝脏样本中获得了REV的LTR的300 bp片段。此前中国鹧鸪中尚未报道过这种疾病。中国鹧鸪可能是其他中国地方鸡的潜在感染源。
