TABLE 4.

Pairwise comparisons of the numbers of amino acid differences and percent similarities in DNA sequences of three genes (rpsA, gidA, and sucB) between Rickettsiella 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		95.3	96.6		91.6	92.0		84.8	81.2
2. I. kingi	14		98.0	22		98.1	47		93.9
3. I. sculptus	10	6		20	5		46	19

^aPairwise comparisons show the numbers of amino acid differences (lower diagonals for each gene) and the percent similarity (upper diagonals for each gene) in the DNA sequences of three genes (rpsA [encoding 298 amino acids], gidA [encoding 262 amino acids], and sucB [encoding 309 to 310 amino acids]). The numbers in column 1 correspond to the comparison number subheadings.
