[The cellular fatty acid composition of bacteria in the family Vibrionaceae].

Vibrio cholerae strains, serovar O1, biovar eltor, subtype Ogawa, isolated from different sources, V. cholerae classica and NAG vibrios have identical cell fatty acid composition with the prevalence of hexadecenoic, hexadecanoic and octadecenoic acids. V. parahaemolyticus and V. alginolyticus fatty acid profiles, being identical, are similar to V. cholerae profile, differing from it mainly by a higher content of dodecanoic acid. The similarity of the fatty acid profiles of Aeromonas sp. and Vibrio strains is indicative of their phylogenetic relationship. The fatty acid composition of Plesiomonas shigelloides characterized by the presence of methylenehexadecanoic acid and at the same time by its similarity to that of Vibrio and Aeromonas in the content of the majority of fatty acids, confirms the position on the intermediate status of the genus Plesiomonas between the families Enterobacteriaceae and Vibrionaceae.
