The entire wbJOY_06 genome was sequenced and was found to comprise 7246 nt excluding the poly(A) tail. The wbJOY_06 isolate was highly divergent from known genotype 1–4 HEV isolates derived from humans, swine, wild boars, deer, mongoose and rabbits (n=145) by 22.6–27.7 %, rat HEV isolates (n=2) by 46.0–46.2 %, and avian HEV isolates (n=5) by 52.5–53.1 % over the entire genome. A Simplot analysis revealed no significant recombination between the existing HEV strains of genotypes 1–4. Therefore, we propose that the wbJOY_06 isolate is the first member of a previously unidentified genotype., UL https://www.microbiologyresearch.org/content/journal/jgv/10.1099/vir.0.029470-0
