A colonization factor (production of lateral flagella) of mesophilic Aeromonas spp. is inactive in Aeromonas salmonicida strains.
The nine laf (lateral flagellum) genes of mesophilic aeromonads are in the Aeromonas salmonicida genome. The laf genes are functional, except for lafA (flagellin gene), which was inactivated by transposase 8 (IS3 family). A pathogenic characteristic of mesophilic aeromonads (lateral flagella) is abolished in this specialized pathogen with a narrow host range.
