Yersinia enterocolitica synthesizes N-acyl-L-homoserine lactone (AHL) signal molecules via the LuxR-LuxI homologues YenR-YenI. In this study we checked two prototypes of mouse-virulent Y. enterocolitica serotype O8 strains WA-314 and 8081 for AHL production in vitro and in vivo (mouse infection model). We used thin-layer chromatography in combination with the Escherichia coli AHL biosensor to identify the AHL species produced. We detected only OHHL [N-(3-oxohexanoyl)-L-homoserine lactone] and not HHL (N-hexanoyl-L-homoserine lactone) produced by Y. enterocolitica O8 in culture supernatant or infected mouse tissue. This is the first report demonstrating AHL production by yersiniae during infection.
