Abstract

The cellular fatty acid composition of (50 strains, including all recognized biovars), (7 strains), and (1 strain) was determined by gas-liquid chromatography. All species showed a generally similar pattern characterized by relatively large amounts of 3-OH-14:0, 16:1, 16:0, 17:0-cyclo, and 18:1. The heterogeneity of as revealed by biochemical reactions and by deoxyribonucleic acid-deoxyribonucleic acid hybridization was not found to be reflected in the fatty acid composition. Only small interspecies differences were detected. differed slightly from by its higher concentrations of 12:0, 16:0, and 17:0 and its lower content of 14:0. was characterized by its high content of 18: 1, low content of 15:0, and absence of 13:0. A reference group of five strains showed a fatty acid pattern grossly comparable to that of yersiniae, but the following differences were noted: the presence in of an additional compound, 2-OH-14:0, relatively high concentrations of 14:0 and 16:0, and low amounts of 15:0, 16:0, and 17:0. Thus, the genus appears relatively homogeneous with respect to fatty acid composition, and the present results do not support per se a splitting of into additional species. Furthermore, the high degree of similarity of the fatty acid patterns of yersiniae and agrees well with the present placement of in the family
