The fatty acid composition of Y. pestis strains, the causative agent of plaque, has been studied. Y. pestis cells have been found to contain great amounts of palmitoleic acid, methylenehexadecanoic acid, oleic acid with elaidic acid, palmitic acid and pentadecanoic acid. Lauric acid, myristic acid, 3-oxymyristic acid and methyleneoctadecanoic acid have been detected in moderate amounts. Vaccine strains, virulent museum and newly isolated strains, while differing in their antigenic structure, have proved to be uniform in their fatty acid composition. In Y. pestis cels, grown on a solid medium for a longer period and at higher temperature, an increased proportion of saturated acids is observed.
