Abstract

Aichi virus 1 (AiV-1) has been proposed as a causative agent of human gastroenteritis. In this study, raw, decanted, and treated wastewater samples from a wastewater treatment plant in an urban area of Dakar, Senegal, were collected. AiV-1 was detected in raw (70%, 14/20), decanted (68.4%, 13/19), and treated (59.3%, 16/27) samples, revealing a noticeable resistance of AiV-1 to chlorine-based treatment. Phylogenetic analysis revealed that all sequences clustered within genotype B. Our study presents the first report on the detection of AiV-1 in the environment of Dakar and constitutes indirect evidence of virus circulation in the population.

塞内加尔城市污水中1型爱知病毒的流行及遗传多样性

爱知病毒1型(AiV-1)被认为是人类胃肠炎的病原体。在这项研究中，收集了来自塞内加尔达喀尔市区一家污水处理厂的未经处理、倒装和处理过的废水样本。在生样品(70%，14/20)、滗析样品(68.4%，13/19)和处理样品(59.3%，16/27)中检测到AiV-1，表明AiV-1对氯基处理具有明显的耐药性。系统发育分析显示，所有序列均聚集在基因型b内。我们的研究首次报道了在达喀尔环境中检测到AiV-1，并构成了病毒在人群中传播的间接证据。
