This chapter deals with Ehrlichia Infections in Animals and covers the three species in the genus that are responsible for the most important veterinary and human ehrlichioses: E. canis, E. chaffeensis, and E. ruminantium. There is an Introduction, which gives a summary of the history and classical biology of these organisms, and this is followed by the extensive Genomics section. Complete genome sequences are available for all three organisms, including those of three different strains of E. ruminantium, and several detailed inter- and intra-species genomic comparisons are described. Topics discussed include genetic and phenotypic variability and genomic insights into the biology and evolution of Ehrlichia. There is a section on the practical applications of genomic knowledge to molecular diagnostics, epidemiology, and vaccine development for Ehrlichia, and the chapter ends with suggestions for future research goals. This chapter shows how genomics has provided new insights into the biology of the previously poorly understood Ehrlichia, which will enhance opportunities for controlling the diseases caused by these organisms.
