We determined the cellular fatty acid composition of reference strains and clinical isolates of each of the three Kingella species, Cardiobacterium hominis, and Eikenella corrodens by using capillary gas chromatography. Kingella denitrificans and Kingella kingae contained myristic (14:0) and palmitic (16:0) acids as major acids, whereas cis-vaccenic (18:1 omega 7c) and palmitic acids were the major acids in Kingella indologenes, C. hominis, and E. corrodens. C. hominis differed from the other four species by the absence of 3-hydroxylauric (3-OH-12:0) acid, from K. indologenes by the presence of 3-hydroxypalmitic (3-OH-16:0) acid, and from E. corrodens by the presence of 3-hydroxymyristic (3-OH-14:0) acid. E. corrodens contained a small amount (2%) of myristic acid, while the other four species contained moderate to large amounts (11 to 31%) of this acid.
我们使用毛细管气相色谱法测定了三种金氏杆菌属细菌、人心杆菌和腐蚀埃肯菌的参考菌株及临床分离株的细胞脂肪酸组成。反硝化金氏杆菌和金氏金杆菌含有肉豆蔻酸(14:0)和棕榈酸(16:0)作为主要脂肪酸,而顺式- vaccenic酸(18:1 ω7c)和棕榈酸是产吲哚金氏杆菌、人心杆菌和腐蚀埃肯菌中的主要脂肪酸。人心杆菌与其他四个菌种的不同之处在于缺乏3-羟基月桂酸(3-OH-12:0),与产吲哚金氏杆菌的不同在于存在3-羟基棕榈酸(3-OH-16:0),与腐蚀埃肯菌的不同在于存在3-羟基肉豆蔻酸(3-OH-14:0)。腐蚀埃肯菌含有少量(2%)的肉豆蔻酸,而其他四个菌种含有中等至大量(11%至31%)的这种酸。
