摘要:

本研究旨在系统评价和分析猪繁殖与呼吸综合征病毒(PRRSV)在我国长三角地区的感染状况,为有效防控PRRSV感染提供科学依据。通过检索中国知网(CNKI)、万方数据知识服务平台、维普中文科技期刊数据库、PubMed和Science Direct等5个主要数据库,收集自1995年PRRSV在中国爆发以来关于长三角区域猪群PRRSV流行情况的文献,并进行系统评价和Meta分析。经过筛选,共纳入36篇文献,样本总数为28 767头猪,其中8 277头为PRRSV阳性。Meta分析结果显示,长三角地区猪群中PRRSV的整体流行率为35.8%(95% CI:0.266, 0.456)。安徽省流行率最高,为51.5%(95%CI:0.321, 0.706),其次为江苏省45.0%(95%CI:0.315, 0.589)和上海市41.2%(95%CI:0.211, 0.629),而浙江省的流行率最低,为31.0%(95%CI:0.213, 0.416)。哺乳仔猪的流行率最高,为34.1%(95%CI: 0.181, 0.521),保育猪为30.4% (95%CI: 0.077, 0.598),育肥猪则最低,为21.5%(95%CI: 0.115, 0.333)。亚组分析和Meta回归分析表明,文献的异质性来源不包括采样地点、采样时间、诊断方法、临床症状、猪的发育阶段和文献质量(P>0.05),而样本类型、饲养模式和健康状况等因素均为影响PRRSV流行率的因素(P < 0.05)。我国长三角地区猪群中PRRSV流行率较高,需持续监测其感染情况,特别是对散养猪群和哺乳仔猪的管理和监测,同时制定针对性的防控措施,降低病毒传播风险。

Abstract:

This study aims to systematically evaluate and analyze the prevalence of porcine reproductive and respiratory syndrome virus (PRRSV) in pig populations within the Yangtze River Delta region of China, providing a scientific basis for effective prevention and control strategies. A comprehensive literature search was conducted across five major databases: China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP Chinese Science and Technology Journals Database, PubMed, and Science Direct. Studies on the prevalence of PRRSV in pig populations in the Yangtze River Delta region, collected since the outbreak of PRRSV in China in 1995, was systematically reviewed and subjected to Meta-analysis. A total of 36 articles were included in the Meta-analysis, involving 28 767 pigs, of which 8 277 tested positive for PRRSV. The overall prevalence of PRRSV in pig populations in the Yangtze River Delta region was 35.8% (95% CI: 0.266, 0.456). Among the provinces, Anhui exhibited the highest prevalence at 51.5% (95% CI: 0.321, 0.706), followed by Jiangsu at 45.0% (95% CI: 0.315, 0.589) and Shanghai at 41.2% (95% CI: 0.211, 0.629). Zhejiang had the lowest prevalence at 31.0% (95% CI: 0.213, 0.416). The highest infection rate was observed in suckling piglets (34.1%; 95% CI: 0.181, 0.521), followed by nursery pigs (30.4%; 95% CI: 0.077, 0.598), and finishing pigs (21.5%; 95% CI: 0.115, 0.333). The subgroup analysis and meta-regression analysis revealed that the heterogeneity in the studies was not associated with sampling location, sampling time, diagnostic methods, clinical symptoms, pig developmental stage, or study quality (P>0.05). However, factors such as sample type, feeding practices, and health status were found to significantly affect the prevalence of PRRSV (P < 0.05). The prevalence of PRRSV in pig populations within the Yangtze River Delta region was high. It is essential to maintain continuous monitoring of PRRSV infections, especially the free-range pig and suckling piglets. Additionally, the development and implementation of targeted prevention and control strategies is critical for reducing the risk of viral transmission.
