需要肠道病毒替代物和可靠的生活废水示踪剂来管理食品和水的微生物质量，因为（废水）水再利用在应对人口增长，城市化和气候变化方面变得更加普遍。辣椒温和斑驳病毒（PMMoV）是一种在生活污水中发现的高浓度植物病原体，是肠道病毒的有前途的替代品，已被纳入全球超过29项与水和食品相关的微生物质量和技术研究。这篇综述整合了来自各学科的现有文献，为PMMoV在各种情况下作为肠道病毒替代物和/或生活污水标记物的实用性提供指导。现有研究的综合结果支持PMMoV作为一种有用的肠道病毒过程指标，因为其在源水中的高浓度允许确定现场，中试和全规模（废水）水处理系统中病毒对数减少的程度。在许多形式的废水处理过程中，PMMoV的减少水平小于或等于其他病毒的减少，这表明在评估新的处理技术时，这种病毒可以作为肠道病毒的替代品。PMMoV作为暴露于未经处理的生活污水的环境沃茨中肠道病毒的指标病毒表现出色，因为它在地下水（72.2%）和地表沃茨（淡水，94.5%和沿海，72.2%）中比其他人类病毒更频繁地检测到，并且浓度更高，病原体共检出率高达72.3%。此外，PMMoV是一种重要的微生物来源追踪标记物，最适合与未经处理的生活污水相关，其合并特异性为90%，合并灵敏度为100%，而人类粪便的合并灵敏度仅为11.3%。少数研究也表明PMMoV可能是监测新鲜农产品和贝类微生物质量的肠道病毒的有用指标病毒，但需要对这些主题进行进一步研究。最后，未来的工作是需要填补知识空白，关于PMMoV的全球特异性和敏感性。
An enteric virus surrogate and reliable domestic wastewater tracer is needed to manage microbial quality of food and water as (waste)water reuse becomes more prevalent in response to population growth, urbanization, and climate change. Pepper mild mottle virus (PMMoV), a plant pathogen found at high concentrations in domestic wastewater, is a promising surrogate for enteric viruses that has been incorporated into over 29 investigations of water- and food-related microbial quality and technology around the world. This review consolidates the available literature from across disciplines to provide guidance on the utility of PMMoV as either an enteric virus surrogate and/or domestic wastewater marker in various situations. Synthesis of the available research supports PMMoV as a useful enteric virus process indicator since its high concentrations in source water allow for identifying the extent of virus log-reductions in field, pilot, and full-scale (waste)water treatment systems. PMMoV reduction levels during many forms of wastewater treatment were less than or equal to the reduction of other viruses, suggesting this virus can serve as an enteric virus surrogate when evaluating new treatment technologies. PMMoV excels as an index virus for enteric viruses in environmental waters exposed to untreated domestic wastewater because it was detected more frequently and in higher concentrations than other human viruses in groundwater (72.2%) and surface waters (freshwater, 94.5% and coastal, 72.2%), with pathogen co-detection rates as high as 72.3%. Additionally, PMMoV is an important microbial source tracking marker, most appropriately associated with untreated domestic wastewater, where its pooled-specificity is 90% and pooled-sensitivity is 100%, as opposed to human feces where its pooled-sensitivity is only 11.3%. A limited number of studies have also suggested that PMMoV may be a useful index virus for enteric viruses in monitoring the microbial quality of fresh produce and shellfish, but further research is needed on these topics. Finally, future work is needed to fill in knowledge gaps regarding PMMoV’s global specificity and sensitivity.
