TABLE 3.

Observed and expected ospC allele diversity in infected vertebrate host species (M. mephitis, striped skunk; M. pennsylvanicus, eastern meadow vole; M. musculus, house mouse; Peromyscus, white-footed/deer mice; S. carolinensis, eastern gray squirrel; T. striatus, eastern chipmunk)^a

	M. mephitis	M. pennsylvanicus	M. musculus	Peromyscus spp.	S. carolinensis	T. striatus
Observed	3	5	3	8	1	12
Mean expected	2.59	5.82	4.26	11.44	1.85	8.68
SD expected	0.54	1.14	0.91	1.19	0.36	1.32
P-value	1	0.78	0.39	0.01	0.30	0.03

^a Allele diversity (“Observed”) was quantified as the number of unique ospC alleles found infecting each host species. The expected number of alleles was found by averaging the expected values across 9,999 randomizations (“Mean expected”); the standard deviation of the mean is also presented (“SD expected”) and the P-value indicating whether the ospC allele diversity in a host species differed from the random expectation.
