The fatty acid methyl ester (FAME) profiles of “Pasteurella” piscicida were determined by gas chromatography and subjected to numerical analysis in comparison with those obtained for Vibrio anguillarum, Aeromonas salmonicida and Pasteurella species of clinical origin. The bacterial species studied shared important characteristics with respect to their FAME content: in all of them the saturated and unsaturated fatty acids of 16 carbon atoms were the predominant fatty acids. However, distinguishing features could be detected for each pathogen. Using either single linkage or complete linkage algorithms, strains were divided into four phena that corresponded to the different species, but showed a high degree of correlation among them. Although single linkage discriminated strains better within each phenum, complete linkage was more useful to establish the relationships among clusters. The results obtained support the idea that “Pasteurella” piscicida is related to members of the genera Vibrio and Aeromonas and indicate the need for exhaustive genetic studies to clarify the taxonomic position of this fish pathogen. |
