Entre ellas, existen seis especies que causan infecciones en humanos, incluyendo Ehrlichia chaffeensis, agente responsable de la Ehrlichiosis Monocítica. No Brasil, estudos sorológicos e moleculares têm avaliado a ocorrência de espécies de Ehrlichia em cães, gatos, animais selvagens e seres humanos.
