Abstract

Newcastle disease, caused by Newcastle disease virus (NDV), poses a significant threat to global poultry production due to its highly contagious nature and diverse genotypes. To assess the current NDV situation in southern China, 335 fecal swab samples were collected from a live poultry market in Foshan, Guangdong Province, between 2023 and 2024. Hemagglutination (HA) testing identified 51 positive samples (15.2 %), followed by RT-PCR confirmation of the M gene in 13 of these samples (3.9 %). Full-length sequencing of the F gene from 12 of the M gene-positive samples (3.6 %) revealed the presence of 12 Class I NDV strains belonging to subtype 1.1.2, highlighting an increasing trend of Class I NDV isolates in the positive samples from this market over time. Our findings underscore the importance of continuous surveillance for NDV, particularly Class I strains, which can be easily overlooked due to their low pathogenicity. The study provides updated data for understanding the evolving epidemic situation of Class I NDV in China, thereby informing the development of effective control strategies to mitigate potential outbreaks and safeguard poultry populations.

应用研究报告：对中国广东一个活禽市场的新城疫病病毒监测显示，ⅰ类新城疫病病毒的流行率呈上升趋势

由新城疫病毒（NDV）引起的新城疫病，由于其高度传染性和基因型的多样性，对全球家禽生产构成重大威胁。为了评估中国南方目前的NDV情况，在2023年至2024年期间从广东省佛山市的一个活禽市场收集了335份粪便拭子样本。血凝（HA）检测鉴定出51份阳性样本（15.2%），随后RT-PCR在其中13份样本中确认M基因（3.9%）。对12份M基因阳性样本（3.6%）的F基因进行全长测序，结果显示存在12株属于1.1.2亚型的I类NDV菌株，表明随着时间的推移，该市场阳性样本中I类NDV分离株呈增加趋势。我们的研究结果强调了持续监测NDV的重要性，特别是由于其低致病性而容易被忽视的I类菌株。该研究为了解中国I类新城疫疫情演变提供了最新数据，从而为制定有效的控制策略提供信息，以减轻潜在的疫情并保护家禽种群。

期刊介绍： The Journal of Applied Poultry Research (JAPR) publishes original research reports, field reports, and reviews on breeding, hatching, health and disease, layer management, meat bird processing and products, meat bird management, microbiology, food safety, nutrition, environment, sanitation, welfare, and economics. As of January 2020, JAPR will become an Open Access journal with no subscription charges, meaning authors who publish here can make their research immediately, permanently, and freely accessible worldwide while retaining copyright to their work. Papers submitted for publication after October 1, 2019 will be published as Open Access papers. The readers of JAPR are in education, extension, industry, and government, including research, teaching, administration, veterinary medicine, management, production, quality assurance, product development, and technical services. Nutritionists, breeder flock supervisors, production managers, microbiologists, laboratory personnel, food safety and sanitation managers, poultry processing managers, feed manufacturers, and egg producers use JAPR to keep up with current applied poultry research.
