Sequence diversity and substitution rates for hypervariable domains HV1 to HV4 and for conserved regions of the ompA genes of 31 M. haemolytica, 6 M. glucosida, and 4 P. trehalosi isolates

Domain	Sequence diversity (%)		d_S^a	d_N^a	d_S/d_N
Domain	Nucleotide	Amino acid	d_S^a	d_N^a	d_S/d_N
HV1	44	67	0.1396 ± 0.1015	0.4064 ± 0.1433	0.71
HV2	42	72	0.0831 ± 0.0601	0.1586 ± 0.0605	0.52
HV3	13	30	0.0000 ± 0.0000	0.0691 ± 0.0404
HV4	33	53	0.1518 ± 0.1244	0.1954 ± 0.0814	0.77
Conserved regions	3	1	0.0211 ± 0.0046	0.0006 ± 0.0004	35.17

d_S is the number of synonymous substitutions per 100 synonymous sites; d_N is the number of nonsynonymous substitutions per 100 nonsynonymous sites. Values are means ± standard deviations.
