Abstract:
Four new variants of Orsay virus were identified from wild isolates of Caenorhabditis elegans nematodes collected from decaying plant matter in France. Near-complete genomes of the viruses were determined by metagenomic sequencing. The four genomes share 96.1-98.9% nucleotide identity with the reference Orsay virus sequence JUv1580.
