Amblyomma hebraeum is a hard tick that infests livestock and wildlife. It also bites humans. The long mouthparts of Amblyomma ticks make them difficult to remove manually; these ticks also leave large wounds that may become infected by bacteria or infested by screwworms. A. hebraeum can transmit Ehrlichia ruminantium (formerly Cowdria ruminantium), the agent of heartwater. This tick also carries Rickettsia africae, the agent of African tick-bite fever, an emerging zoonosis in rural sub-Saharan Africa and the Caribbean.
