Anatomy and physiology. A hard-bodied tick of the family Ixodidae, the lone star tick. Ticks, like mites, are arthropods that have lost the segmentation of the abdomen (or opisthosoma) that their ancestors had, with a subsequent fusion of the abdomen with the cephalothorax (or prosoma ).

Tick-borne diseases, which afflict humans and other animals, are caused by infectious agents transmitted by tick bites. They are caused by infection with a variety of pathogens, including rickettsia and other types of bacteria, viruses, and protozoa. Because individual ticks can harbor more than one disease-causing agent, patients can be ...
The Argasidae are the family of soft ticks, one of the two families of ticks. The family contains 193 species, although the composition of the genera is less certain, and more study is needed before the genera can become stable. The currently accepted genera are Antricola, Argas, Nothoaspis, Ornithodoros, and Otobius.
The Acarina, or Acari, are the mites and ticks. They are an order of Arachnids. Their fossil history goes back to the Devonian era. Most acarines are tiny: less than a millimetre. It is estimated that over 50,000 species have been described, but a million or more species may be currently living. The study of mites and ticks is called acarology.
Pathogenesis. Tick paralysis is believed to be due to toxins found in the tick's saliva that enter the bloodstream while the tick is feeding. The two ticks most commonly associated with North American tick paralysis are the Rocky Mountain wood tick (Dermacentor andersoni) and the American dog tick (Dermacentor variabilis); however, 43 tick species have been implicated in human disease around ...

This hard tick, commonly known as a deer tick, is also the vector for other tick-associated illnesses, such as Lyme disease. Many species of Babesia only infect nonhuman mammalian hosts, most commonly cattle, horses, and sheep. B. microti and B. divergens are the two main pathogenic species in humans.
However, transmission is quite rare, with only about 1.2 to 1.4 percent of recognized tick bites resulting in Lyme disease. In Europe, the vector is Ixodes ricinus, which is also called the sheep tick or castor bean tick. In China, Ixodes persulcatus (the taiga tick) is probably the most important vector.
