A total of 36 strains of Campylobacter species were examined for isoprenoid quinones and cellular fatty acids. The isoprenoid quinone content was determined by reverse-phase high-pressure liquid chromatography, and the fatty acids were determined by capillary gas-liquid chromatography. All Campylobacter species contained menaquinone-6 (2-methyl-3-farnesyl-farnesyl-1,4-naphthoquinone) and a methyl-substituted menaquinone-6 (2,[5 or 8]-dimethyl-3-farnesyl-farnesyl-1,4-napthoquinone) as the major isoprenoid quinones. The latter menaquinone has not been reported in other bacteria and may prove to be a useful chemical marker of Campylobacter species. Campylobacter jejuni and most Campylobacter coli were distinguished from other campylobacteria by the presence of a C19 cyclopropane acid, and Campylobacter sputorum subsp. mucosalis differed from other species by the presence of lauric acid.
共对36株弯曲杆菌进行了类异戊二烯醌和细胞脂肪酸检测。类异戊二烯醌含量通过反相高压液相色谱法测定,脂肪酸通过毛细管气液色谱法测定。所有弯曲杆菌均含有甲基萘醌-6(2-甲基-3-法呢基-法呢基-1,4-萘醌)和一种甲基取代的甲基萘醌-6(2,[5或8]-二甲基-3-法呢基-法呢基-1,4-萘醌)作为主要类异戊二烯醌。后一种甲基萘醌在其他细菌中尚未见报道,可能被证明是弯曲杆菌的一种有用化学标志物。空肠弯曲菌和大多数结肠弯曲菌通过存在C19环丙烷酸与其他弯曲杆菌区分开来,而唾液弯曲菌黏膜亚种与其他菌种的区别在于存在月桂酸。
