Argasidae

[är′gas·ə‚dē]
(invertebrate zoology)
The soft ticks, a family of arachnids in the suborder Ixodides; several species are important as ectoparasites and disease vectors for humans and domestic animals.

Argasidae

 

a family of parasitic ticks of the superfamily Ixodoidea. The body is flattened, oval, and 3–30 mm long. The integument is leathery. Hungry argasidae are gray or yellow-brown in color; after filling up with blood, they become purplish.

There are five genera of Argasidae, containing about 100 species. In the USSR there are 17 species, belonging to three genera: the tick (Argas), Alveonasus, and Ornithodoros. They are distributed in countries with a warm climate; in the USSR they are found in the southern European area, the Caucasus, Middle Asia, and Kazakhstan.

All Argasidae feed on the blood of terrestrial vertebrates; they hide in the burrows and nests of animals and in holes and cracks in the earth and in buildings; they usually attack their animal hosts at night. When sucking blood, the Argasidae swell up tremendously. They can also go hungry for years. In man, the bites of the Argasidae cause itching and a red blister on the skin. The Argasidae are carriers of a number of animal and human diseases.

These soft-shelled Argasidae ticks differ from hard Ixodidae ticks in several key characteristics: they have multiple nymphal stages; they feed rapidly, typically between 15 and 90 minutes; as adults, they can feed and reproduce repeatedly, are capable of surviving for several years between blood meals (73); and the spirochetes may colonize their salivary glands, rather than the midgut, allowing for rapid deposition after host attachment.
11 Ticks are classified into three families: (1) the Ixodidae, or hard ticks; (2) the Argasidae, or soft ticks; and (3) the Nuttalliellidae, a much lesser known family, with characteristics of both hard and soft ticks.

Both Ixodidae (hard) and Argasidae (soft) ticks can be reservoirs of the organism with greater than 40 species of ticks serving as natural reservoirs that remain infected throughout life and can transmit the bacterium transovarially.
Tick biology--There are three families of ticks recognized in the world today: (1) Ixodidae (hard ticks), (2) Argasidae (soft ticks), and (3) Nuttalliellidae, a small, curious, little-known group with some characteristics of both hard and soft ticks (Varma, 1993).
Ticks are hematophagous acarines mainly distributed in two major families, Ixodidae (hard tick) and Argasidae (soft tick) (BLACK & PIESMAN, 1994), while only one tick species is present in the Nuttalliellidae family (GUGLIELMONE et al.
