Estimates of average evolutionary divergence of concatenated sequence pairs between and within M. bovis clades

	Evolutionary divergence
	Clade A	Clade B	M.b.-Cameroon	M.b.-Oman/Turkey	M.b.-Ethiopia	Distance (SE)
Clade A						0.001 (0.001)
Clade B	0.003					0.001 (0.000)
M.b.-Cameroon	0.006	0.005				n/c
M.b.-Oman/Turkey	0.012	0.012	0.010			n/c
M.b.-Ethiopia	0.012	0.012	0.010	0.003		n/c
M. agalactiae	0.030	0.030	0.029	0.029	0.027	n/c

The numbers of base substitutions per site are shown as calculated from the average substitutions of all sequence pairs between (matrix) and within (column) groups. Standard error estimates are shown in parentheses. n/c: not calculated.
