This study assessed wastewater quality through the quantification of four human enteric viruses and the applicability of pepper mild mottle virus (PMMoV) and tobacco mosaic virus (TMV) as indicators of viral reduction during wastewater treatment. Thirty-three samples were collected from three steps of a wastewater treatment plant in Southern Louisiana, USA for a year between March 2017 and February 2018. Noroviruses of genogroup I were the most prevalent human enteric viruses in influent samples. The concentrations of PMMoV in influent samples (5.9 ± 0.7 log10 copies/L) and biologically treated effluent samples (5.9 ± 0.5 log10 copies/L) were significantly higher than those of TMV (P < 0.05), and the reduction ratio of PMMoV (1.0 ± 0.8 log10) was found comparable to those of TMV and Aichi virus 1. Because of the high prevalence, high correlations with human enteric viruses, and lower reduction ratios, PMMoV was deemed an appropriate indicator of human enteric viral reduction during wastewater treatment process.

在美国路易斯安那州南部的一家污水处理厂减少人类肠道病毒和指示病毒。
这项研究通过量化四种人类肠道病毒以及胡椒轻度斑驳病毒(PMMoV)和烟草花叶病毒(TMV)作为废水处理过程中病毒减少的指标的适用性来评估废水质量。在2017年3月至2018年2月之间的一年中,从美国南部路易斯安那州的污水处理厂的三个步骤中收集了33个样品。基因组I的诺如病毒是进样中最普遍的人类肠道病毒。进水样品(5.9±0.7 log 10拷贝/ L)和经生物处理的出水样品(5.9±0.5 log 10拷贝/ L)中的PMMoV浓度显着高于TMV(P <0.05),并且降低率PMMoV(1.0±0.8对数10)被发现与TMV和爱知病毒1具有可比性。由于高流行,与人类肠病毒的高度相关以及降低的降低率,PMMoV被认为是废水处理过程中人类肠道病毒减少的合适指标。
