Abstract

Ornithobacterium rhinotrachealis (ORT) and Pasteurella multocida (PM) are two major bacterial pathogens affecting the United States (US) commercial turkey industry. This retrospective observational case-case study aimed to investigate the association between land cover and confirmed disease occurrences attributed to PM or ORT in commercial turkey sites located in the Midwestern US A total of 65 farms from one poultry production company were included, where 28 had PM disease occurrences and 37 had ORT disease occurrences between 2014 and 2021. Risk factors of interest included land cover types (wetlands, forest, urban, pasture, herbaceous, barren, shrub), poultry-farm density in the area, and season and year of confirmed outbreak(s). A multivariable logistic regression model revealed that for every 1 m increase in distance from a farm to the nearest wetland, the odds of a confirmed disease occurrence related to PM decreased by approximately 0.24% compared to an ORT-related disease occurrence (p = 0.004). Meanwhile, PM occurrence during 2014-2017 was 98.5% higher than 2018-2019 and 93.2% higher than in 2020-2021. Broadly, the findings contribute to the dearth of research on land cover and turkey respiratory diseases and demonstrate that land cover is an important consideration for farm management and future study.

探讨土地覆盖对禽细菌病和家禽霍乱发生的影响：个案研究。

鼻气管炎鸟杆菌（ORT）和多杀性巴氏杆菌（PM）是影响美国商业火鸡行业的两种主要细菌病原体。这项回顾性观察性个案研究旨在调查位于美国中西部的商业火鸡养殖场的土地覆盖与PM或ORT引起的确诊疾病发病率之间的关系。该研究共纳入了一家家禽生产公司的65个农场，其中28个发生PM疾病，37个发生ORT疾病。感兴趣的危险因素包括土地覆盖类型（湿地、森林、城市、牧场、草本、贫瘠、灌木）、该地区家禽养殖场密度以及确认暴发的季节和年份。多变量logistic回归模型显示，与ort相关的疾病发生率相比，从农场到最近的湿地的距离每增加1米，与PM相关的确诊疾病发生率降低约0.24% （p = 0.004）。与此同时，2014-2017年PM的发生率比2018-2019年高98.5%，比2020-2021年高93.2%。总的来说，这些发现导致了土地覆盖和火鸡呼吸系统疾病研究的缺乏，并表明土地覆盖是农场管理和未来研究的重要考虑因素。

期刊介绍： Animals (ISSN 2076-2615) is an international and interdisciplinary scholarly open access journal. It publishes original research articles, reviews, communications, and short notes that are relevant to any field of study that involves animals, including zoology, ethnozoology, animal science, animal ethics and animal welfare. However, preference will be given to those articles that provide an understanding of animals within a larger context (i.e., the animals'' interactions with the outside world, including humans). There is no restriction on the length of the papers. Our aim is to encourage scientists to publish their experimental and theoretical research in as much detail as possible. Full experimental details and/or method of study, must be provided for research articles. Articles submitted that involve subjecting animals to unnecessary pain or suffering will not be accepted, and all articles must be submitted with the necessary ethical approval (please refer to the Ethical Guidelines for more information).
