¹Reference groups: low dose and S. Cubana.

²Notation i→j denotes transition from state i to j with intensity q_ij. The 5 states are labeled 1, 2, 3, 4 and 5, denoting: 1-latency; 2-continuous shedding; 3-intermittent non-shedding state; 4-intermittent shedding state; and 5-recovery.

³Notations 6, 9, C, Y, D, and T denote the low dose, high dose, S. Cubana, S. Yoruba, S. Derby and S. Typhimurium, respectively.

⁴SE standard errors of the mean ratios of transition intensities.
