Table 1. Recovery of F. novicida genotypes from populations of mice and ticks exposed to large- or small-pool genotype populations.

	Large genotype pools		Small genotype pools
	Pool A	Pool B	Pool C	Pool D	Pool E
No. of genotypes in pool	93	94	16	17	16
No. genotypes recovered from mouse cohort (% of total genotypes in pool)	78 (84%)	76 (81%)	16 (100%)	17 (100%)	16 (100%)
No. genotypes recovered from tick cohort* (% of total genotypes recovered from mouse)	59 (76%)	41 (54%)	13 (81%)	15 (88%)	15 (94%)

*all genotypes detected in ticks were also detected in mice.
