In November 2014, New South Wales Health was notified of a cluster of respiratory illness in a veterinary school. Active case finding identified another case at a local equine stud. All cases had exposure to the equine fetal membranes of Mare A. This tissue subsequently tested positive for using quantitative real-time polymerase chain reaction. We conducted a cohort study of the university and stud farm staff to determine risk factors for disease. Nine people were exposed to the fetal membranes of Mare A. Of these, five cases of psittacosis were identified. Two required hospital admission. Contact with birds was not associated with illness (RR = 0.5, 95% CI = 0.09-2.73). People who had direct contact with the abnormal fetal membranes were more likely to develop disease (RR = 11.77, 95% CI = 1.02-∞). The emergence of an association between horse exposure and infection has important implications for the prevention and control of psittacosis. : Investigation of an outbreak of psittacosis in a rural veterinary school demonstrates novel source of infection for psittacosis through exposure to abnormal equine fetal membranes.
2014年11月，新南威尔士州卫生部接到通知，一所兽医学校出现了一批呼吸道疾病病例。通过主动病例排查，在当地一个养马场又发现了一例病例。所有病例都接触过A母马的马胎膜。随后，使用定量实时聚合酶链反应检测发现该组织呈阳性。我们对该大学和种马场的工作人员进行了一项队列研究，以确定疾病的风险因素。有9人接触过A母马的胎膜。其中，确诊了5例鹦鹉热病例。2例需要住院治疗。接触鸟类与疾病无关（相对危险度=0.5，95%置信区间=0.09-2.73）。直接接触异常胎膜的人患病的可能性更大（相对危险度=11.77，95%置信区间=1.02-∞）。马匹接触与感染之间关联的出现对鹦鹉热的预防和控制具有重要意义。：对一所农村兽医学校鹦鹉热疫情的调查表明，通过接触异常马胎膜是鹦鹉热新的感染源。
