TABLE 3.

Pairwise comparisons of the numbers of nucleotide differences and percent similarities in DNA sequences of three genes (rpsA, gidA, and sucB) between Rickettsiella spp. in three species of ixodid tick: Ixodes angustus, I. kingi, and I. sculptus

Tick host	Pairwise comparisonsa
	rpsA			gidA			sucB
	1	2	3	1	2	3	1	2	3
1. I. angustus		85.6	90.2		86.7	86.3		82.6	83.0
2. I. kingi	93		97.5	105		98.1	162		96.0
3. I. sculptus	88	22		108	15		158	37

^aPairwise comparisons show the numbers of amino acid differences (lower diagonals for each gene) and the percent similarities (upper diagonals for each gene) in the DNA sequences of three genes (rpsA [894 bp], gidA [787 bp], and sucB [928 to 931 bp]). The numbers in column 1 correspond to the comparison number subheadings.
