摘要 从一名确诊为幽门螺杆菌感染的胃炎患者幽门样本分离得到1株革兰氏染色阴性的菌株F不产芽胞,无运动,生长范围为10~40℃,最适生长温度为37℃,生长的pH5-10。细胞壁脂肪酸主要是anteiso-C15:0(40.27%),iso-C15:0(15.14%)和C16:0(10.37%);主要的呼吸醌是MK-7(H2)和MK-8(H2);DNA的G+C百分含量为71.5%。与Kocuria polaris CMS76T16S rRNA相似性为99.865%,通过系统发育分析表明该菌株与Kocuria polaris CMS76T在同一个分支,亲缘关系最近,综合生理学、化学及遗传学特征分析表明菌株F是Kocuria polari的一个新亚种。
