IL10 and infection: 3) Hyperinfectious strains exhibited significantly reduced stimulation of IL-10 relative to S. Typhimurium 14028 irrespective of LB or LPM pH 5.5 growth conditions (P<0.05); such reduced stimulation was most pronounced at later infection time points (i.e., 10-fold at t = 8 h under LPM pH 5.5 conditions).
