Evaluating putative virulence factors: “molecular Koch’s postulates”

on 3.9.08 with 0 comments



  • suspected virulence trait should be associated significantly more often with pathogenic strains than with non-pathogenic strains

  • specific inactivation of genes associated with suspected virulence trait should lead to a measurable decrease in virulence

  • replacement of inactivated genes with wild-type version should restore pathogenicity

  • these are straightforward ideas
