Table 2.

Estimated differences in mean tonsillar serotype 9 loads (in log₁₀ eq. CFU/sample) between pigs exposed to serotype 9 only (‘Mono’) and to both serotype 2 and 9 (‘Dual’) on different days post exposure ¹.

	Inoculated Pigs		Contact Exposed Pigs

^1,2 See legend Table 1; ³ The estimated mean load at 1 DPE in dual group (i.e., the intercept of the final model) was 1.46 log₁₀ eq. CFU/sample and 1.32 log₁₀ eq. CFU/sample for the inoculated and contact pigs, respectively.
