Ornithodoros

Ornithodoros is a genus of soft ticks in the family Argasidae. They are known to be vectors of various diseases in humans and animals, including relapsing fever and African swine fever.

Description[edit | edit source]

Ornithodoros ticks are characterized by their soft, leathery exoskeleton. Unlike hard ticks, they do not have a scutum, or dorsal shield. The mouthparts are not visible from above as they are located on the ventral side of the body. The body is oval in shape and can expand significantly when engorged with blood.

Life cycle[edit | edit source]

The life cycle of Ornithodoros ticks includes egg, larva, nymph, and adult stages. After a blood meal, a female tick lays several hundred eggs. The eggs hatch into six-legged larvae, which then molt into eight-legged nymphs. The nymphs undergo several molts before becoming adults. Unlike hard ticks, Ornithodoros ticks can survive long periods without feeding.

Disease transmission[edit | edit source]

Ornithodoros ticks are vectors of various diseases. They are known to transmit the spirochete bacteria Borrelia, which causes relapsing fever in humans. They are also vectors of African swine fever virus, which causes a highly contagious and deadly disease in pigs.

Control[edit | edit source]

Control of Ornithodoros ticks is challenging due to their ability to survive long periods without feeding. However, strategies such as the use of acaricides, habitat modification, and the development of vaccines are being explored.
