Southern Tick-Associated Rash Illness (STARI) Amblyomma Americanumor Lone Star Tick (Hard Tick) — Infectious Agent Not Yet Identified.
The following is a list of tick-borne diseases that may be found in the world wide, the usual tick vector(s), and the organism responsible for the disease that the tick transmits:
- Lyme disease (borreliosis) — Ixodes species (also known as black-legged ticks) including deer ticks (hard ticks) — vectors for Borrelia species of bacteria (a spirochete or spiral-shaped bacterium)
- Babesiosis — Ixodes species (hard ticks) — vectors for Babesia, a protozoan
- Ehrlichiosis — Amblyomma americanum or lone star ticks (hard ticks) — vectors for Ehrlichia chaffeensis and Ehrlichia ewingii bacterial species
- Rocky Mountain spotted fever — Dermacentor variabilis (American dog tick) and Rocky Mountain wood tick (Dermacentor andersoni) (hard tick) are the primary vectors and occasionally the brown dog tick (Rhipicephalus sanguineus); Amblyomma cajennense (hard tick) is the vector in countries south of the United States — vectors for Rickettsia bacteria
- Southern Tick-Associated Rash Illness (STARI) Amblyomma Americanumor Lone Star Tick (Hard Tick) — Infectious Agent Not Yet Identified According To U.S. Centers For Disease Control And Prevention (CDC); Some Researchers Suggest Borrelia Lonestari May Be The Infectious Agent.
- Tick-borne relapsing fever — Ornithodoros moubata or African tick (soft tick) — vectors for Borrelia species of bacteria
- Tularemia Dermacentor variabilis (American dog tick) (hard tick) and Amblyomma americanum or lone star tick (hard tick) — vectors for Francisella tularensis bacteria
- Anaplasmosis (human granulocytic anaplasmosis or HGA) — Ixodes species (hard tick) — vectors for Anaplasma phagocytophilum bacteria
- Colorado tick fever Dermacentor andersoni (hard tick) — vectors for Coltivirus, an RNA virus
- Powassan encephalitis — Ixodes species and Dermacentor andersoni (both hard ticks) — vectors for Powassan encephalitis virus, an RNA arbovirus
- Q fever Rhipicephalus sanguineus, Dermacentor andersoni, and Amblyomma americanum (all three are hard ticks) — vectors for Coxiella burnetii, a bacterium
- African cattle disease Rhipicephalus evertsi also known as red ticks — vector for parasites or bacterial infections in cattle
- Heartland viral disease Amblyomma americanum or lone star tick (hard tick) — new viral disease discovered in 2012 in South/Central U.S.
