Results of the negative binomial regression which examined the impacts of long-term prescribed burning, year, quarter, and wildlife occurrence on the number of ticks encountered per hour that were infected with pathogenic bacteria.

	Coefficient (SE)	RR (95% CI)	P
Any Burning (vs. No Burning*)	−0.65 (1.17)	ND	0.579
Season (Warm [Spring/Summer] vs Cool* [Fall/Winter])	2.51 (1.26)	ND	0.047
Any Burn X Season	−3.43 (1.65)	ND	0.037
Constant	−3.50 (0.92)	NA	<0.001
ln(effort)	1 (exposure)

SE = Standard error. RR = Relative rate. ND = Not determined; RR is not given because it depends on the interacting variable. NA = Not applicable.

*Indicates the reference category.
