Hundreds of species of ticks have been documented throughout the world. These arachnids consume blood for nutrients and are capable of introducing a bevy of disease pathogens while feeding. While some tick bites are innocuous, they are associated with diseases: Rocky Mountain spotted fever, ehrlichiosis, Lyme disease, tularemia, babesiosis and relapsing fever.
The American dog tick transmits Rocky Mountain spotted fever most commonly. Ehrlichiosis is caused by the transmission of the bacteria Ehrlichia by tick bite. Ehrlichia is known to attack healthy blood cells. The deer tick as well as the lone star tick carries Lyme disease caused by the bacteria Borrelia burgdorferi. It is important to seek medical attention if there are concerns of disease transmission from a tick bite.
