Phenotypic and Genomic Characteristics of sp. nov. Isolated from the Stomachs of Pigs in Beijing.

is among the four main causes of gastroenteritis worldwide. Most reported infections are caused by and . However, other emerging pathogens have been recognized as important pathogens in humans and animals. A novel bacterial strain, PS10, was isolated from the gastric mucous of pigs in 2022 in Beijing, China. The cell was Gram-negative, microaerobic, motile, and negative for catalase, oxidase, and urease. Phylogenetic and phylogenomic analyses based on the 16S rRNA gene and core genome indicated that this isolate belongs to the genus . There were low dDDH relatedness and ANI values shared within this strain and its closest species below the cut-off values generally recognized for isolates of the same species. The draft genome size of PS10 is 2,240,910 bp in length with a percentage of DNA G+C contents of 37.72%. Comparing the phenotypic and phylogenetic features among this isolate and its related organisms, strain PS10 represents a novel species within the genus , for which the name sp. nov. (Type strain PS10 = GDMCC 1.3686 = JCM 35849) is proposed.
