Abstract

To test the importance of flagella as a virulence factor, virulent strain Pseudomonas aeruginosa M-2 was mutagenized, and a Fla^- mutant was isolated. An M-2 Fla^- spontaneous motile revertant was isolated from M-2 Fla^-. The three strains were biochemically and morphologically identical. Assay of Fla⁺ in the burned-mouse model showed a severe loss of virulence. The Fla⁺ revertant was fully virulent. The immportance of P. aeruginosa motility (flagella) for virulence in burns infections is indicated.
