  1. Least Squares Means and standard errors (LSM ± SE) of the bacterial colony spreading (BCSp) (µm) measured from the colonies of the highly (HV) and low virulent (LV) isolates inoculated modified Shieh broths 24 h after addition of the appropriate cortisol concentrations [cortisol] (µg/L).
  2. a,bRefer to significant differences within one virulence group (HV or LV).
