[The composition of the cellular fatty acids in bacteria of the genera Yersinia and Francisella].
The studied strains of Yersinia pseudotuberculosis (5 st.), Y. enterocolitica (2 st.), Y. intermedia (1 st.), Y. frederiksenii (1 st.), Y. kristensenii (1 st.) and Y. ruckeri (1 st.) have similar fatty acid profiles of cells mainly represented by straight chain and cyclopropanic fatty acids with chain of 12 to 19 carbon atoms. Prevalence of C16:1, C16:0, C17v, in the spectrum and C18:1 under growth in meat-peptone broth are observed. Strains of Y. pseudotuberculosis as well as the already studied vaccine strain Y. pestis differ from yersiniae of other species by the lower level of dodecanoic acid. Bacteria of species Francisella tularensis (6 st.) are characterized by a wide range of straight-chain saturated and monounsaturated fatty acids with 10-26 carbon atoms. Yersiniae and francisellae preserve the proper fatty acid profiles under cultivation on various nutrient media and on the same medium (agarized medium with aminopeptide). Results obtained confirm close relationship of yersiniae of the studied species as well as phylogenetic remoteness and taxonomic isolation of yersiniae and francisellae.
