Abstract

See full text

A method for predicting the pathogenicity and virulence of a strain of Gram-negative bacteria of the Enterobacteriaceae family, wherein the amount of 2-hydroxymyristate and/or 2-hydroxymyristic acid present in the lipopolysaccharides of the bacteria is identified and measured, the amount of 2-hydroxymyristate and/or 2-hydroxymyristic acid is compared with a reference value, and wherein it is concluded that the strain is virulent if the amount of 2-hydroxymyristate is greater than the reference value. Also, the use of the 2-hydroxymyristic acid ester as a marker of pathogenicity and virulence of a Gram-negative bacterial strain and an in vitro diagnosis kit implementing this marker.
