a
ID50, median infectious dose for the strain carrying an inlA PMSC mutation (CSUFSL N1-040); c, the shift in ID50 for the outbreak-associated epidemic clone strain (CSUFSL N1-054) relative to CSUFSL N1-040; a, the intercept of the dose-response curve; b, slope of the dose-response curve.
b
dof, degrees of freedom.
