Many hard ticks are of considerable medical importance, acting as vectors of diseases caused by bacteria, protozoa, and viruses, such as Rickettsia and Borrelia. [2] Other tick-borne diseases include Lyme disease , babesiosis , ehrlichiosis , Rocky Mountain spotted fever , anaplasmosis , Southern tick-associated rash illness , tick-borne ...
In general, soft ticks transmit pathogens within minutes of attachment because they feed more frequently, whereas hard ticks take hours or days, but the latter are more common and harder to remove. [19] For an individual to acquire infection, the feeding tick must also be infected. Not all ticks are infected.
Dermacentor variabilis, also known as the American dog tick or wood tick, is a species of tick that is known to carry bacteria responsible for several diseases in humans, including Rocky Mountain spotted fever and tularemia (Francisella tularensis). It is one of the best-known hard ticks. Diseases are spread when it sucks blood from the host.
Ixodes is a genus of hard-bodied ticks (family Ixodidae). It includes important disease vectors of animals and humans (tick-borne disease), and some species (notably Ixodes holocyclus) inject toxins that can cause paralysis. Some ticks in this genus may transmit the pathogenic bacterium Borrelia burgdorferi [3] responsible for causing Lyme disease.
Ticks are widely distributed around the world, especially in warm, humid climates. Ticks belong to two major families, the Ixodidae or hard ticks, and the Argasidae, or soft ticks. Nuttalliella, a genus of tick from southern Africa, is the only member of the family Nuttalliellidae, and represents the most primitive living lineage of ticks ...

Relapsing fever is a vector-borne disease caused by infection with certain bacteria in the genus Borrelia, [1] which is transmitted through the bites of lice, soft-bodied ticks (genus Ornithodoros), or hard-bodied ticks (Genus Ixodes). [2] [3]
