Noda-Like RNA Viruses Infecting Caenorhabditis Nematodes: Sympatry, Diversity, and Reassortment.

ABSTRACT: Three RNA viruses related to nodaviruses were previously described to naturally infect the nematode Caenorhabditis elegans and its relative, Caenorhabditis briggsae Here, we report on a collection of more than 50 viral variants from wild-caught Caenorhabditis. We describe the discovery of a new related virus, the Mělník virus, infecting C. briggsae, which similarly infects intestinal cells. In France, a frequent pattern of coinfection of C. briggsae by the Santeuil virus and Le Blanc virus was observed at the level of an individual nematode and even a single cell. We do not find evidence of reassortment between the RNA1 and RNA2 molecules of Santeuil and Le Blanc viruses. However, by studying patterns of evolution of each virus, reassortments of RNA1 and
