摘要

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。

Prevalence and Genetic Diversity of Aichi Virus 1 from Urban Wastewater in Senegal.

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.

期刊介绍： ''Intervirology'' covers progress in both basic and clinical virus research, and aims to provide a forum for the various disciplines within virology. Issues publishing original papers alternate with thematic issues, focusing on clearly defined topics. This thematic concentration serves to make timely reviews, research reports and controversy easily accessible to both specialists in the field and those who want to keep track of the latest developments outside their own area of interest. In addition to original papers, regular issues publish short communications and letters to the editor to provide readers with a forum for the exchange of ideas and comments. The scope encompasses work on the molecular biology of human and animal viruses, including genome organization and regulation, and the structure and function of viral proteins. The pathogenesis, immunology, diagnosis, epidemiology, prophylaxis and therapy of viral diseases are considered.
