The analysis of the chromatograms of methyl esters of fatty acids in bacterial strains of the tribe Klebsielleae showed the heterogeneity of the fatty acid composition of bacteria belonging to the genera Klebsiella, Enterobacter, Hafnia and Serratia. The bacteria of this tribe could be subdivided into 5 provisory groups in accordance with the composition and profile of their fatty acids. Group I comprised K. pneumoniae K1, K. ozaenae and K. rhinoscleromatis strains forming a separate group characterized by the absence of cyclopropane fatty acids; group II comprised K. pneumoniae strains of other capsular serovars (K2, K8, K11, K13, K41, K47), as well as K. aerogenes and K. oxytoca strains. The fatty acid composition of the strains of group III, comprising E. aerogenes and E. cloacae, was similar to that of E. coli O1; only among the fatty acids of these bacteria acid C20:0 could be detected. H. alvei strains were included into group IV; their fatty acid profiles were similar to those of the genus Enterobacter, but had a higher content of acids C15:0 and C18:0. S. marcescens strains were similar to the strains of group II in their fatty acid composition, but considerably differed from the latter by a higher content of hexadecanoate (C16:0) and a lower level of C18:1; for this reason they were regarded as provisory group V.
对克雷伯菌族细菌菌株中脂肪酸甲酯色谱图的分析表明，克雷伯菌属、肠杆菌属、哈夫尼亚菌属和沙雷菌属细菌的脂肪酸组成具有异质性。根据该族细菌的脂肪酸组成和图谱，可将其细分为5个暂定组。第一组包括肺炎克雷伯菌K1、臭鼻克雷伯菌和鼻硬结克雷伯菌菌株，它们形成一个单独的组，其特征是不存在环丙烷脂肪酸；第二组包括其他荚膜血清型的肺炎克雷伯菌菌株（K2、K8、K11、K13、K41、K47），以及产气克雷伯菌和产酸克雷伯菌菌株。第三组包括产气肠杆菌和阴沟肠杆菌，其脂肪酸组成与大肠杆菌O1相似；在这些细菌的脂肪酸中，只能检测到酸C20:0。蜂房哈夫尼亚菌菌株被归入第四组；它们的脂肪酸图谱与肠杆菌属相似，但酸C15:0和C18:0的含量较高。粘质沙雷菌菌株的脂肪酸组成与第二组菌株相似，但十六烷酸（C16:0）含量较高，C18:1水平较低，与后者有很大差异；因此，它们被视为暂定第五组。
