  2. Tick Borne Diseases • Ticks are external parasites that feed on the blood of vertebrates • Tick-borne pathogens: fungi, bacteria, protozoa, and viruses. • Ixodidae, or hard ticks, and Argasidae or soft ticks. • Tick-borne diseases are diseases which are spread between animals by the bite of an infected tick • Ticks become infected by feeding on animals that are either sick from disease, or are healthy but have the parasite in their blood (carriers) • Ticks infect animals when they feed on them, through their saliva • A single infected tick can pass disease on to an animal

  3. Lyme Disease • Where it occurs • Caused by: a spirochete bacterium (Borrelia burgdorferi) • Carried by: deer ticks • The tick’s hosts are many.

  7. Rocky Mountain Spotted Fever • Where it occurs • Caused by: a bacterium, Rickettsia rickettsii • Carried by: Rocky Mountain wood tick and American dog tick

  8. Relapsing Fever • Where it occurs • Caused by: many spirochetes (a bacteria) species from the Borrelia genus • Carried by: soft ticks of the Ornithodoros genus

  9. Tularemia (or Rabbit fever) • Where it occurs • Caused by: bacterium (Francisella tularensis) • Carried by: Rocky Mountain wood tick, lone star tick, and American dog tick

  10. Tick Paralysis • Where it occurs • Caused by: a neurotoxin produced in the salivary glands of a female tick • Carried by: deer tick, dog tick, Rocky Mtn. wood tick, and Lone Star tick

  11. Conclusion • These diseases can cause severe discomfort and sometimes even death if left untreated. • Caution should be taken when entering likely tick habitats.
