*Sequences for partial 16S rRNA, GroEl, and SodB genes are compared with GenBank database sequences from Ehrlichia ruminantium, E. canis, E. chaffeensis, E. ewingii, Anaplasma marginale, A. phagocytophilum, and Neorickettsia risticii.
†GenBank sequence accession numbers for 16S rRNA, GroEl, and SodB for Ehrlichia sp. from horses in Nicaragua are KJ434178, KJ434179, and KJ434180, respectively.
