Ixodes

A genus of hard-bodied ticks in the family Ixodidae. Some species are vectors of disease.

• I. angustus — a dog tick.
• I. canisuga — a dog tick found also on foxes and occasionally other species in Europe.
• I. cookei — found on most species.
• I. cornuatus — found on dogs and other species in Australia; may cause paralysis.
• I. dammini — a three-host tick, important transmitter of Borrelia burgdorferi in the USA.
• I. hexagonus — the hedgehog tick, found also on dogs and other species in Europe.
• I. holocyclus — a tick of bandicoots in Australia; found also on other species. Transmits Coxiella burnetii and causes tick paralysis by a toxin secreted by its salivary glands. It also produces a cardiovascular component which causes intense vasoconstriction, high blood pressure and death.
• I. kingi — the rotund tick of dogs.
• I. loricatus — a very rare infestation in New World primates.
• I. muris — the mouse tick, found on dogs.
• I. ornithorhynchi — the platypus tick.
• I. pacificus — the California black-legged tick, found on most species.
• I. persulcatus — transmits Babesia spp.
• I. pilosus — bush, sour-veld or russet tick found on most species. Does not cause paralysis.
• I. ricinus — the castor-bean tick, found on many species of mammals and birds in Europe. Transmits Babesia divergens, B. bovis, Anaplasma, tick pyemia, Coxiella burnetii, several human encephalitides and also causes paralysis.

• I. rubicundus — infests most species but not cat, horse or bird. Causes paralysis.
• I. rugosus — found on dogs.
• I. scapularis — shoulder or black-legged tick; found on most species. May transmit anaplasmosis and tularemia.
• I. sculptus — found on dogs.
• I. texanus — found on dogs.

Ixodes is a genus of hard-bodied ticks (family Ixodidae). It includes important disease vectors of animals and humans (tick-borne disease). Some ticks in this genus may transmit the pathogenic bacterium Borrelia burgdorferi^[1] responsible for causing Lyme disease. Additional organisms that may be transmitted by Ixodes are parasites from the genus Babesia which cause Babesiosis, and bacteria from the related genera Ehrlichia which cause Ehrlichiosis and Anaplasma which cause Anaplasmosis.

Ticks can be transmitted through handling of livestock such as cows, horses and domestic deer.^{[citation needed]}
