Ornithobacterium rhinotracheale (ORT) has been considered exotic to New Zealand and thus, any samples from poultry suspected of ORT infection are submitted as part of an exotic disease investigation managed by Ministry for Primary Industries (MPI) and subjected to standardized test protocols carried out in the physical containment level 3+ laboratory at MPI's Animal Health Laboratory (AHL). All previous exotic disease investigations concerning ORT produced negative results by bacterial culture and conventional PCR. Following the recent introduction of a real-time PCR for ORT at the AHL, several tracheal wash fluids from backyard chickens ( Gallus gallus domesticus ) were tested positive. This identification constituted the first detection of ORT in New Zealand poultry. As a result, a second premise was investigated with further samples testing positive for ORT by molecular assays. This paper describes the two exotic disease investigations associated with the first detection of ORT in New Zealand poultry and its implications.
禽气管鸟杆菌（ORT）被认为是新西兰的外来病菌，因此，任何疑似感染ORT的家禽样本都作为初级产业部（MPI）管理的外来疾病调查的一部分提交，并在MPI动物健康实验室（AHL）的3+级物理隔离实验室中按照标准化测试方案进行检测。此前所有关于ORT的外来疾病调查通过细菌培养和传统PCR检测均呈阴性。在AHL最近引入ORT实时PCR检测后，几只后院鸡（家鸡）的气管冲洗液检测呈阳性。这一鉴定结果构成了新西兰家禽中首次检测到ORT。因此，对第二个场所进行了调查，更多样本通过分子检测呈ORT阳性。本文描述了与新西兰家禽中首次检测到ORT相关的两项外来疾病调查及其影响。
