Animals amusing and assisting humans
Clive R. Hollin in An Introduction to Human–Animal Relationships, 2021
A study carried out in the Italian Alps was reported by Alasaad et al. (2012), who used dogs trained to detect the scent of Sarcoptes-infected animals to find sick animals and infected carcasses. Sarcoptic mange is a highly contagious skin disease caused by a mite burrowing through the skin, resulting in intense itching and irritation; the scratching causes most of the animal's hair to fall out. The rapid detection and removal of dead animals and treatment of the sick animals, even when they are under snow, is crucial in containing this infectious disease, but is problematic in the wild. The detector dogs successfully assisted in finding the carcasses of mangy wild animals, mainly Alpine ibex and several species of deer, and in the capture of mange-infected wild animals.
Infestations, insect bites and stings
Ronald Marks, Richard Motley in Common Skin Diseases, 2019
The species of mites causing scabies in animals are similar to those causing human scabies, but do not give rise to scabies infestation in humans. Contact with infested animals may cause transient lesions of human skin and, occasionally, living animal scabies mites have been found in human skin but animal scabies does not cause the same clinical picture as human scabies and burrows are not found. Sarcoptic mange may be seen in horses, cattle, pigs, monkeys, guinea pigs, sheep and goats, but the most common animal scabies to cause problems is that found in dogs or cats. The correct management is to treat the animal appropriately on veterinary advice and to give any topical anti-itch preparation to the human patient for the affected site. With proven human scabies infestation it is important to look for the human contacts – not the animal contacts.

Demodex folliculorum, which is known as follicle mange factor in humans, is a mite that belongs to the Demodicidia family of prostigmata. It is 0.1–0.4 mmlong, fusiform-shaped, and has 4 pairs of legs and a large abdomen. Demodexfolliculorum mostly resides in the bottom parts of hairs on the face, hair follicles and in the skin fat-secreting glands of the skin in humans (Desch and Nutting 1972; Nutting 1976; Markell et al. 1992; Zeytun 2017). The infestation of the eyelash follicle occurring due to D. Folliculorum is called demodicosis (Topcu et al. 2005). The pathologic changes of Demodex infestations include the obstruction of the base of eyelash follicles and of the mouths of the sebaceous gland, reactive hyperkeratinization of the eyelids, epithelial hyperplasia and inflammatory reactions to the parasitic structure; the mites also play a role as a mechanical vector for bacterial infection (Roihu and Kariniemi 1998).
A single subcutaneous administration of a sustained-release ivermectin suspension eliminates Psoroptes cuniculi infection in a rabbit farm

Psoroptes cuniculi mange in rabbits is a serious threat to the host health. The control of mites is very important for keeping the health of rabbits and ensuring the development of rabbit husbandry. Due to its high potency against ear mites and high safety to rabbits, MLs (e.g. IVM, doramectin, and moxidectin) are widely used to control P. cuniculi mange in rabbits. For instance, a dosage of two subcutaneous administrations of moxidectin at 0.2 mg/kg 10 days apart have been shown effective to control ear mites mange in rabbits [10]. An intramuscular injection of doramectin was effective against P. cuniculi infestation [6]. Ivermectin was effective to control ear mites in rabbits through repeated subcutaneous administration at 0.2 mg/kg. Other studies have shown that to control P. cuniculi in rabbits, three or more doses of IVM (formulated as 1% solution) were generally needed [21–23].
Facts and ideas from anywhere

Although clearly responsible for a great many evils, oil has also been key to the growth of human civilization. Bitumen, a naturally forming liquid found in oil sands and pitch lakes, was used in ancient times for waterproofing boats and baskets. As early as the 4th century, the Chinese were drilling for oil with bamboo pipes and burning it as heating fuel. It was used for treatment of mange in camels. By the 9th century, Persian alchemists had discovered how to distill oil into kerosene to make light.
