    Two novel Gram-stain-negative, Oxidase-positive, catalase-negative, aerobic, non-motile and coccus-shaped bacterial strains (ZJ142T and ZJ171) were isolated from the respiratory tract of marmots collected from Yushu Tibetan Autonomous Prefecture (Altitude: 3600 m; N: 33°13'57'', E: 97°1'11'') in Qinghai Province. The 16S rRNA genes of strains ZJ142T and ZJ171 are most similar to Moraxella porci DSM 25326T (99.04%). The phylogenetic tree based on th... ...点击完成人机验证后继续浏览

    从青海省玉树藏族自治州（海拔：3600米；北纬：33°13'57"，东经：97°1'11"）采集的旱獭呼吸道中分离出了两个革兰氏染色阴性、氧化酶阳性、触酶阴性和非运动性的球形细菌新菌株（ZJ142T 和 ZJ171）。菌株 ZJ142T 和 ZJ171 的 16S rRNA 基因与猪摩拉克菌 DSM 25326T（99.04%）最为相似。基于 16S rRNA 基因的系统发育树和基于 700 个单拷贝核心基因的系统发生树表明，ZJ142T 和 ZJ171 菌株在摩拉克菌属内形成了一个独特的分支。两个新菌株表现出同源平均核苷酸一致性值 (ANI) ≤ 77.0% 和数字 DNA-DNA 杂交值 (dDDH) ≤ 25.4%，确认了它们的独特性。ZJ142T 菌株和 ZJ171 的 dDDH 值为 73.3%，ANI 值为 97.1%。与摩拉克菌属的其他物种相比，这两个菌株具有相似的菌落形态、生长条件，并且能够水解Esculin。基于表型、系统发育和生理学的结果，将两个菌株归类为摩拉克菌属的一个新种，我们建议命名为旱獭摩拉克菌（Moraxella marmotae sp. nov.），模式菌株 ZJ142T = GDMCC 1.3113T = JCM 35324T）。在模式菌株 ZJ142T 中，我们预测了脂寡糖（LOS）、纤毛和亚硝酸盐还原酶以及其它毒力基因的生物合成基因簇。考虑到我们的分离物来自呼吸道来源，并且摩拉克菌属中已知最著名的病原体是摩拉克氏卡他莫拉菌（Moraxella catarrhalis），这是一种众所周知的人类呼吸道致病菌，因此新发现的旱獭摩拉克菌可能是潜在的病原体。
