Diversity of lake bacteria promotes human echovirus inactivation.

ABSTRACT: Human enteric viruses can remain infective in surface waters for extended periods of time, posing a public health risk. Microbial activity contributes to the inactivation of waterborne enteric viruses, but while individual bacteria-virus interactions have been characterized, the importance of microbial diversity remains unknown. Here, we experimentally manipulated the diversity of bacterial communities from Lake Geneva across three seasons using a dilution-to-extinction approach and monitored the inactivation and genome decay of echovirus 11, a member of the Enterovirus genus. Long-read sequencing of the 16S rRNA gene revealed diversity gradients ranging between 373 and 2,722 bacterial species. Compared to sterile controls, echovirus 11 inactivation was enhanced by the presence of a
