Abstract

In October 2024, a broiler farm located south of Nouakchott, Mauritania, reported respiratory symptoms, diarrhoea, and 10% mortality within a flock of 4500 birds. Pooled organ samples (n = 6) were collected and screened by real-time RT-PCR for H5 and H9 subtype avian influenza viruses, Newcastle disease virus, infectious bronchitis virus, and infectious laryngotracheitis virus. Six samples were positive for H9. Full genome sequencing of a representative sample revealed that the viruses were H9N2 and belonged to lineage G5.5. Several molecular markers associated with adaptation to mammalian hosts were identified indicating the virus' potential to infect humans. Analysis of the eight segments showed that the virus was not a reassortant and that it was similar to H9N2 viruses identified in Senegal. This is the first report of H9N2 in Mauritania, and the data generated will be of interest to national and regional veterinary and public health authorities.

毛里塔尼亚某肉鸡养殖场H9N2禽流感检测及特征分析2024.

2024年10月，毛里塔尼亚努瓦克肖特南部的一个肉鸡养殖场报告了4500只鸡的呼吸道症状、腹泻和10%的死亡率。收集合集器官标本（n = 6），采用实时荧光定量pcr技术对H5、H9亚型禽流感病毒、新城疫病毒、传染性支气管炎病毒、传染性喉气管炎病毒进行检测。6份样本H9阳性。有代表性样本的全基因组测序结果显示，该病毒为H9N2，属于G5.5谱系。发现了与适应哺乳动物宿主有关的几个分子标记，表明该病毒具有感染人类的潜力。对8个片段的分析表明，该病毒不是重组病毒，与在塞内加尔发现的H9N2病毒相似。这是毛里塔尼亚的第一份H9N2报告，所产生的数据将对国家和区域兽医和公共卫生当局有意义。

期刊介绍： Veterinary Research Communications publishes fully refereed research articles and topical reviews on all aspects of the veterinary sciences. Interdisciplinary articles are particularly encouraged, as are well argued reviews, even if they are somewhat controversial. The journal is an appropriate medium in which to publish new methods, newly described diseases and new pathological findings, as these are applied to animals. The material should be of international rather than local interest. As it deliberately seeks a wide coverage, Veterinary Research Communications provides its readers with a means of keeping abreast of current developments in the entire field of veterinary science.
