Scabies is caused by infection with the female mite Sarcoptes scabiei var. hominis, an ectoparasite. [3] The mites burrow into the skin to live and deposit eggs. [3] The symptoms of scabies are due to an allergic reaction to the mites. [2] Often, only between 10 and 15 mites are involved in an infection. [2]
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 ...

Benzyl benzoate is an effective and inexpensive topical treatment for human scabies. [7] It has vasodilating and spasmolytic effects and is present in many asthma and whooping cough drugs. [8] It is also used as an excipient in some testosterone-replacement medications (like Nebido) for treating hypogonadism. [9]
Common scab is a plant disease of root and tuber crops caused by a small number of Streptomyces species, specifically S. scabies, S. acidiscabies, S. turgidiscabies and others. Common scab mainly affects potato ( Solanum tuberosum ), but can also cause disease on radish ( Raphanus sativus ), parsnip ( Pastinaca sativa ), beet ( Beta vulgaris ...
Streptomyces scabiei (also wrongly named Streptomyces scabies) [1] is a streptomycete bacterium species found in soils around the world. [2] Unlike most of the 500 or so Streptomyces species it is a plant pathogen causing corky lesions to form on tuber and root crops as well as decreasing the growth of seedlings.
