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.
是全球范围内肠胃炎的四大主要病因之一。大多数报告的感染是由 和 引起的。然而，其他新兴病原体已被确认为人和动物中的重要病原体。2022年在中国北京，从猪的胃黏液中分离出一种新型细菌菌株PS10。该细胞为革兰氏阴性、微需氧、有运动性，过氧化氢酶、氧化酶和尿素酶检测呈阴性。基于16S rRNA基因和核心基因组的系统发育和系统基因组分析表明，该分离株属于 属。该菌株与其最接近的物种之间的dDDH相关性和ANI值较低，低于通常认可的同物种分离株的临界值。PS10的基因组草图长度为2,240,910 bp，DNA G+C含量百分比为37.72%。比较该分离株与其相关生物的表型和系统发育特征，菌株PS10代表 属内的一个新物种，为此提出名称 新种（模式菌株PS10 = GDMCC 1.3686 = JCM 35849）。
