Samples from 77 chital (Axis axis), 42 fallow (Dama dama), 26 red (Cervus elaphus), 7 rusa (Cervus timorensis) and 1 sambar deer (Cervus unicolor) were examined. Yersinia pseudotuberculosis infection was diagnosed as the cause of death in 6 (23%) of the red and 23 (30%) of the chital deer. Yersiniosis was the most common infectious cause of death diagnosed. Affected deer were usually found moribund or dead, often with faecal staining of the perineum. Gross pathology in chital included a fibrinous enterocolitis, enlarged congested mesenteric lymph nodes and multiple pale foci through the liver. Gross changes in red deer were limited to intense congestion of the intestinal mucosa and enlargement and congestion of mesenteric lymph nodes. Microscopic intestinal changes in both species consisted of microabscessation or diffuse suppurative inflammation of the intestinal mucosa with numerous bacterial colonies in the lamina propria. Multifocal suppurative mesenteric lymphadenitis was a common finding. Multifocal suppurative or non-suppurative hepatitis was frequently present in the liver of chital but was uncommon in the red deer. Yersiniosis occurred during the cooler months from June to November, with younger age classes most commonly affected. Y. pseudotuberculosis serotypes I, II and III were isolated in the ratio 17:3:0 in the chital deer and 1:1:2 in red deer. The clinical, epidemiological and bacteriological features are similar to those documented previously by New Zealand workers. The increased susceptibility to disease of red deer and chital compared to fallow deer and perhaps other species has not previously been documented.
对77只花鹿（印度花鹿）、42只黇鹿（欧洲黇鹿）、26只马鹿（赤鹿）、7只帝汶鹿（帝汶麂）和1只水鹿（黑鹿）的样本进行了检测。在6只（23%）马鹿和23只（30%）花鹿中，耶尔森氏假结核菌感染被诊断为死亡原因。耶尔森氏菌病是诊断出的最常见的传染性死亡原因。受感染的鹿通常被发现濒死或已死亡，会阴处常有粪便污渍。花鹿的大体病理学表现包括纤维素性小肠结肠炎、肠系膜淋巴结肿大充血以及肝脏出现多个苍白病灶。马鹿的大体变化仅限于肠道黏膜强烈充血以及肠系膜淋巴结肿大和充血。两种鹿的微观肠道变化均包括微脓肿形成或肠道黏膜弥漫性化脓性炎症，固有层有大量细菌菌落。多灶性化脓性肠系膜淋巴结炎是常见表现。花鹿肝脏中经常出现多灶性化脓性或非化脓性肝炎，但在马鹿中并不常见。耶尔森氏菌病发生在6月至11月较凉爽的月份，幼龄鹿最常受影响。在花鹿中分离出的耶尔森氏假结核菌血清型I、II和III的比例为17:3:0，在马鹿中为1:1:2。临床、流行病学和细菌学特征与新西兰研究人员之前记录的相似。与黇鹿以及可能的其他物种相比，马鹿和花鹿对疾病的易感性增加此前尚未有记录。
