^aSimilarity index was calculated following pairwise alignment of E.muris P29 protein sequences with or thologs in other ehlichial genomes by the Lipman-Pearson method using the MegAlign program (DNASTAR Inc., Madison, WI)

^bTandem Repeats Finder program was used to identify the tandem repeats in the sequences

^cShort four-amino acid tandem repeats of less than three numbers present in these sequences are not included in the analysis

^dProportion of protein in repeats expressed in percent

^eCalculated isoelectric point (pI)
