title: [Fatty-acid composition of cells and lipopolysaccharides in different Yersinia species under the conditions of growth at low temperature].
abstract: Y. pestis, Y. pseudotuberculosis, Y. enterocolitica, Y. frederiksenii, Y. intermedia, Y. kristensenii and Y. ruckeri grown at 4 degrees C were characterized by fatty acid composition with a high content of C16:1 and C18:1, as well as the proportion of saturated to nonsaturated fatty acids equal to, on the average, 2.0. In Yersinia lipopolysaccharides a relatively high level of C16:1 and C12:0 was observed with the prevalence of 3-OH-C14:0. In the fatty-acid spectra of both cells and lipopolysaccharides no essential difference was noted. Thus, during growth at low temperature differences, earlier detected in the studied Yersinia species grown at 37 degrees C and making it possible to divide 7 Yersinia species into 2 groupes, were completely leveled. These results confirmed the close phylogenetic relationship between the Yersinia species under study and were indicative of more pronounced biological community of Yersinia under the conditions of growth at low temperature.
