Conferencias Magistrales. Ehrlichiosis y anaplasmosis humanas en América. Human Ehrlichiosis and Anaplasmosis in America. J. Stephen Dumler. 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.
