摘要

背景:塞内卡病毒A (Senecavirus A, SVA)是一种新发现的小核糖核酸病毒科病毒,可引起猪的水疱性病变、跛行,甚至新生儿仔猪死亡。近年来,SVA在世界范围内迅速蔓延,特别是在亚洲。目的:我们进行了一项全球荟萃分析和系统综述,以确定猪SVA感染的状况。方法:通过2014年至2020年7月26日的PubMed、VIP中文期刊数据库、中国知识基础设施和万方数据检索数据,按照我们的纳入标准共纳入34篇文章。我们通过随机效应模型估计了猪中SVA的总流行率。进行了研究的偏倚风险评估和亚组分析以解释异质性。结果:我们估计SVA患病率为15.90% (1,564/9,839;95%可信区间[CI], 44.75-65.89)。患病率降至11.06% (945/ 8542);95% CI, 28.25-50.64)。基于vp1的RT-PCR和免疫组织化学检测的SVA患病率最高为58.52% (594/ 1015;95% CI, 59.90-83.96)和85.54% (71/83;95% CI, 76.68-100.00)。仔猪群中SVA患病率最高,为71.69% (119/166;95% CI, 68.61 ~ 98.43) (p < 0.05)。此外,我们的分析证实,亚群,包括国家、采样年份、采样位置、检测基因、检测方法、季节、年龄和气候,可能是与SVA患病率相关的异质因素。结论:结果表明SVA目前在各国广泛存在。因此,应制定更多的防控政策,加强养猪场管理,改善养殖条件和环境,以减少SVA的传播。

Prevalence of Senecavirus A in pigs from 2014 to 2020: a global systematic review and meta-analysis.

Background: Senecavirus A (SVA), a member of the family Picornaviridae, is newly discovered, which causes vesicular lesions, lameness in swine, and even death in neonatal piglets. SVA has rapidly spread worldwide in recent years, especially in Asia.

Objectives: We conducted a global meta-analysis and systematic review to determine the status of SVA infection in pigs.

Methods: Through PubMed, VIP Chinese Journals Database, China National Knowledge Infrastructure, and Wanfang Data search data from 2014 to July 26, 2020, a total of 34 articles were included in this analysis based on our inclusion criteria. We estimated the pooled prevalence of SVA in pigs by the random effects model. A risk of bias assessment of the studies and subgroup analysis to explain heterogeneity was undertaken.

Results: We estimated the SVA prevalence to be 15.90% (1,564/9,839; 95% confidence interval [CI], 44.75-65.89) globally. The prevalence decreased to 11.06% (945/8,542; 95% CI, 28.25-50.64) after 2016. The highest SVA prevalence with the VP1-based RT-PCR and immunohistochemistry assay was 58.52% (594/1,015; 95% CI, 59.90-83.96) and 85.54% (71/83; 95% CI, 76.68-100.00), respectively. Besides, the SVA prevalence in piglet herds was the highest at 71.69% (119/166; 95% CI, 68.61-98.43) (p < 0.05). Moreover, our analysis confirmed that the subgroups, including country, sampling year, sampling position, detected gene, detection method, season, age, and climate, could be the heterogeneous factors associated with SVA prevalence.

Conclusions: The results indicated that SVA widely exists in various countries currently. Therefore, more prevention and control policies should be proposed to enhance the management of pig farms and improve breeding conditions and the environment to reduce the spread of SVA.
