The Ixodidae are the family of hard ticks or scale ticks, [1] one of the three families of ticks, consisting of over 700 species. They are known as 'hard ticks' because they have a scutum or hard shield, which the other major family of ticks, the 'soft ticks' ( Argasidae ), lack. They are ectoparasites of a wide range of host species, and some ...
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 responsible for causing Lyme disease.

Unlike the Ixodidae that have no fixed dwelling place except on the host, they live in sand, in crevices near animal dens or nests, or in human dwellings, where they come out nightly to attack roosting birds or emerge when they detect carbon dioxide in the breath of their hosts. Ixodidae remain in place until they are completely engorged.

Ixodes ricinus is a three-host tick: larvae, nymphs and adults feed on different hosts where larvae and nymphs prefers small to medium-sized animals and adults tend to feed on large-sized animals. This tick species feeds on a broad range of mammals, birds and reptiles and frequently bites humans. Ixodes ricinus is involved in the transmission ...
Mar 18, 2024 · Background Amblyomma is the third most diversified genus of Ixodidae that is distributed across the Indomalayan, Afrotropical, Australasian (IAA), Nearctic and Neotropical biogeographic ecoregions, reaching in the Neotropic its highest diversity. There have been hints in previously published phylogenetic trees from mitochondrial genome, nuclear rRNA, from combinations of both and morphology ...
Improved understanding of tick phylogeny has allowed testing of some biogeographical patterns. On the basis of both literature data and a meta-analysis of available sequence data, there is strong support for a Gondwanan origin of Ixodidae, and probably Ixodida. A particularly strong pattern is observed for the genus Amblyomma, which appears to have originated in Antarctica/southern South ...
The Ixodidae and Argasidae are large and cosmopolitan families, whereas the Nuttalliellidae has one species which has only been found in South Africa and Tanzania (Evans, 1992). The main host of Nuttalliella namaqua is uncertain, as is the life cycle (Oliver, 1989). Most ixodid ticks have three hosts, one for each stage of the life cycle ...
