Abstract

In this study, the prevalence of Avian orthoavulavirus-1 (AOAV-1) (also commonly known as Newcastle disease virus) was investigated in caged birds kept in bird markets in the Lahore district of Pakistan. A total of 354 swab samples were obtained from 14 different species of clinically healthy birds. The overall virus prevalence was 12.7% in 9 out of the 14 species. Phylogenetic analysis of the complete fusion protein (F) gene showed that 23 isolates from different avian species belonged to sub-genotype VII.2 while three isolates of pigeon origin clustered with sub-genotype XXI.1.2. The VII.2 viruses isolated had a high nucleotide identity to viruses repeatedly isolated from poultry in Pakistan from 2011 to 2018. To date, sub-genotype XXI.1.2 viruses have only been identified in Pakistan. These findings suggest that the Newcastle disease (ND) outbreaks occurring in Pakistan involve multiple hosts and environments. The study emphasises the importance of continuing to monitor multiple avian species for the presence of AOAV-1s and implementing effective ND control strategies.

从巴基斯坦拉合尔地区笼养鸟类中分离禽正交病毒 1 亚基因型 VII.2 和 XXI.1.2 并进行系统发育分析--短讯。
本研究调查了巴基斯坦拉合尔地区鸟类市场饲养的笼养鸟类中禽类正粘病毒-1(AOAV-1)(通常也称为新城疫病毒)的流行情况。研究人员从 14 种不同的临床健康鸟类身上采集了 354 份拭子样本。在 14 个物种中,9 个物种的病毒总流行率为 12.7%。完整融合蛋白(F)基因的系统发育分析表明,来自不同禽类的 23 个分离株属于亚基因型 VII.2,而来自鸽子的 3 个分离株属于亚基因型 XXI.1.2。分离出的 VII.2 病毒与 2011 年至 2018 年期间从巴基斯坦家禽中反复分离出的病毒具有很高的核苷酸同一性。迄今为止,亚基因型XXI.1.2病毒仅在巴基斯坦发现过。这些发现表明,巴基斯坦发生的新城疫(ND)疫情涉及多种宿主和环境。这项研究强调了继续监测多种禽类是否存在 AOAV-1s 并实施有效的 ND 控制策略的重要性。
