Scabies; Other names: Seven-year itch [1] Magnified view of a burrowing trail of the scabies mite. The scaly patch on the left was caused by scratching and marks the mite's entry point into the skin. The mite has burrowed to the top-right, where it can be seen as a dark spot at the end. Specialty: Infectious disease, dermatology: Symptoms
The scabies mite Sarcoptes scabiei var. hominis goes through four stages in its lifecycle: egg, larva, nymph, and adult. Upon infesting a human host, the adult female burrows into the stratum corneum (outermost layer of skin), where she deposits two or three eggs per day. These oval eggs are 0.1–0.15 mm (0.0039–0.0059 in) long and hatch as ...
In some cases, the self-limiting nature of a colony may be advantageous to the continued survival of the colony, such as in the case of parasites. If their numbers became too high, they would kill the host, and thus themselves. In other cases, self-limitation restricts the viability of predators, thus ensuring the long-term survival of rare ...

Notoedric mange, also referred to as Feline scabies, is a highly contagious skin infestation caused by an ectoparasitic and skin burrowing mite Notoedres cati (Acarina, Sarcoptidae). N. cati is primarily a parasite of felids , but it can also infest rodents , lagomorphs , and occasionally also dogs and foxes.
An ectoparasiticide is an antiparasitic drug used in the treatment of ectoparasitic infestations. [1] These drugs are used to kill the parasites that live on the body surface.
Sarcoptes in humans is especially severe symptomatically, and causes the condition scabies noted above. [citation needed] Another genus of mite which causing itching but rarely causes hair loss because it burrows only at the keratin level, is Cheyletiella. Various species of this genus of mite also affect a wide variety of mammals, including ...
Scabiosa / s k eɪ b i ˈ oʊ s ə / [2] is a genus in the honeysuckle family (Caprifoliaceae) of flowering plants. [3] Many of the species in this genus have common names that include the word scabious, but some plants commonly known as scabious are currently classified in related genera such as Knautia and Succisa; at least some of these were formerly placed in Scabiosa.
