Abstract
The gene coding for toxic shock syndrome toxin-1 in S. aureus was inactivated by allelic replacement in two TSS-associated strains. One mutant derived from FRI1169 (a non-enterotoxigenic strain) lacked virulence in the rabbit uterine chamber infection model. This suggests that TSST-1 is the only determinant produced by this strain that can induce the symptoms of shock in rabbits. A novel method for allelic replacement involving transduction of plasmid integrants is described.Keywords
