Nematodirus spp. are among the most common nematodes of ruminants worldwide. N. oiratianus and N. spathiger are distributed worldwide as highly prevalent gastrointestinal nematodes, which cause emerging health problems and economic losses. Accurate identification of Nematodirus species is essential to develop effective control strategies for Nematodirus infection in ruminants. Mitochondrial DNA (mtDNA) could provide powerful genetic markers for identifying these closely related species and resolving phylogenetic relationships at different taxonomic levels.

We report here the complete genome sequence of Japanese encephalitis virus (JEV) strain SDWF-2021, isolated from a Culex mosquito pool in a duck farm located in Shandong, China. The isolated JEV genetically belong to genotype I, which is the dominant genotype circulation in China.
