    本系统评价和荟萃分析调查了副溶血性弧菌的患病率,它的毒力因子,抗菌素耐药性(AMR),及其在虾中的抗性决定因素。本研究是根据系统评价和荟萃分析(PRISMA)指南的首选报告项目进行的。确定和选择2020年1月至2022年12月发表的相关同行评审文章。搜索策略涉及多个在线数据库,包括谷歌学者,PubMed,ScienceDirect,还有Scopus.纳入标准侧重于检查副溶血性弧菌患病率的研究,毒力因子,以及从农场到零售店的虾中的AMR。共分析了32项研究,显示虾中副溶血性弧菌的汇总估计患病率为46.0%,观察到显著的异质性。亚组分析强调了各大洲不同的患病率,强调需要进一步调查。毒力因子分析确定了最常见的热稳定直接溶血素(tdh)和tdh相关溶血素(trh)。表型AMR分析表明对糖肽有明显的抗性,硝基呋喃,和β-内酰胺。然而,对虾养殖中抗菌药物的使用与观察到的耐药模式之间的相关性尚无定论。漏斗图表明潜在的出版偏见,这表明需要对研究结果进行谨慎的解释。这项研究强调了协调努力解决副溶血性弧菌AMR的紧迫性,以保障公众健康并确保可持续的水产养殖实践。
    This systematic review and meta-analysis investigates the prevalence of Vibrio parahaemolyticus, its virulence factors, antimicrobial resistance (AMR), and its resistance determinants in shrimp. This study was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, to identify and select relevant peer-reviewed articles published between January 2020 and December 2022. The search strategy involved multiple online databases, including Google Scholar, PubMed, ScienceDirect, and Scopus. The inclusion criteria focused on studies that examined V. parahaemolyticus prevalence, virulence factors, and AMR in shrimp from farms to retail outlets. A total of 32 studies were analyzed, revealing a pooled estimate prevalence of V. parahaemolyticus in shrimp at 46.0%, with significant heterogeneity observed. Subgroup analysis highlighted varying prevalence rates across continents, emphasizing the need for further investigation. Virulence factor analysis identified thermostable direct hemolysin (tdh) and tdh-related hemolysin (trh) as the most common. Phenotypic AMR analysis indicated notable resistance to glycopeptides, nitrofurans, and beta-lactams. However, the correlation between antimicrobial usage in shrimp farming and observed resistance patterns was inconclusive. Funnel plots suggested potential publication bias, indicating a need for cautious interpretation of findings. This study underscores the urgency of coordinated efforts to address AMR in V. parahaemolyticus to safeguard public health and to ensure sustainable aquaculture practices.
