Abstract

Lumpy skin disease (LSD) is a contagious viral transboundary disease listed as a notifiable disease by the World Organization of Animal Health (WOAH). The first case of this disease was reported in Pakistan in late 2021. Since then, numerous outbreaks have been documented in various regions and provinces across the country. The current study primarily aimed to analyze samples collected during LSD outbreaks in cattle populations in the Sindh and Punjab provinces of Pakistan. Phylogenetic analysis was conducted using partial sequences of the GPCR, p32, and RP030 genes. Collectively, the LSDV strains originating from outbreaks in Pakistan exhibited a noticeable clustering pattern with LSDV strains reported in African, Middle Eastern, and Asian countries, including Egypt, the Kingdom of Saudi Arabia, India, China, and Thailand. The precise reasons behind the origin of the virus strain and its subsequent spread to Pakistan remain unknown. This underscores the need for further investigations into outbreaks across the country. The findings of the current study can contribute to the establishment of effective disease control strategies, including the implementation of a mass vaccination campaign in disease-endemic countries such as Pakistan.

摘要

结节性皮肤病(LSD)是一种传染性病毒性跨界疾病,被世界动物卫生组织(WOAH)列为须申报疾病。2021年末,巴基斯坦报告了该疾病的首例病例。自那时起,该国各地区和省份均记录到大量疫情爆发。本研究主要旨在分析在巴基斯坦信德省和旁遮普省牛群结节性皮肤病疫情期间采集的样本。使用GPCR、p32和RP030基因的部分序列进行了系统发育分析。总体而言,源自巴基斯坦疫情的结节性皮肤病病毒(LSDV)毒株与在非洲、中东和亚洲国家(包括埃及、沙特阿拉伯王国、印度、中国和泰国)报告的LSDV毒株呈现出明显的聚类模式。病毒毒株的起源及其随后传播至巴基斯坦的确切原因仍然未知。这突出表明需要对该国各地的疫情进行进一步调查。本研究结果有助于制定有效的疾病控制策略,包括在巴基斯坦等疾病流行国家开展大规模疫苗接种运动。
