Research Paper On Face Mites

Dermatofibromas (also known as Fibrous histiocytoma and Fibroma simplex, Nodular subepidermal fibrosis, Sclerosing hemangioma), are common noncancerous (benign) small skin growths. Dermatofibromas are typically detected on the arms and legs. Other common areas are located on breast, face and hands. This growth is usually a benign, single structure that resembles a nipple. Its appearance can be discolored and contains hard, scar-like tissue. A minor injury such as an insect bite, puncture or most recently discovered arsenic, can result in the formation of a dermatofibroma. These growths or nodes only can be found on humans and have not been reported or found other animals. It is estimated that only 1:10 women

The Northern fowl mite (Ornithonyssus sylviarum) is the most common external parasite found on poultry. As the Northern fowl mite feeds on blood if poultry have heavy infestations it can cause anemia. The mite's development from egg to egg-laying adult takes about one week under optimum conditions (cool months are more favorable than warm months). While adult mites do not lay a large number of eggs, populations can increase rapidly on a susceptible bird and may exceed 20,000 mites in only a few weeks. Clinical signs of infestation include decreased egg production, decreased growth rate, and decreased feed consumption. Furthermore, Northern fowl mites can bite humans which will lead to itching and irritation of the skin.

Pediculosis capitis is the infestation of head lice, tiny insects that feed on the blood from the human scalp. According to Mayo CLinic, it usually results from the direct transfer of lice from the hair of one person to the hair of another. A lot of people think that if somebody has lice they have poor personal hygiene, but this has been proven untrue, lice like a clean scalp to feed off of. According to Mayo Clinic, because head lice are spread primarily by head-to-head contact, the risk of transmission is greatest among younger people who play or go to school together. In the United States, cases of head lice most often occur in children in preschool through middle school.

There are several types of mites that can live in the dog's ears, but the most common is otodectes cynotis/Otodectic Mite, i.e. are small eight-legged parasites that feed on wax and oil on the dog's ear canal. A mite have a life cycle for 3 weeks, and can be seen with the naked eye. These mites can cause irritation and inflammation, can infect the outer ear canal and in, and can also cause skin infections or ear infections are more serious if left untreated. When the infection usually results in a distinctive black muck, and in some cases, the ear canal can become completely clogged by dirt-black.

The path of a mite's burrow looks like a line of tiny blisters on the skin. Larvae hatch from the eggs and live under the skin's surface, where they develop into adult mites. Scabies is a fairly common infectious disease that occurs sporadically and also sometimes in outbreaks. Most outbreaks occur in nursing homes, institutions, and child-care centers.

Trombiculid mites usually lay egg on soil, leaves or grass about 40 eggs/month and hatch in next 1-2 weeks (5) after deutovum phase, 6 legged larvae or Chigger mites clime to plants and wait for host. Normal mites require 80% of humidity in air so that they are not found up to 30 cm. of ground (6). Chigger mites feed on vertebrate hosts such as small mammals, birds and reptiles, for 3-4 days (5), they feed by penetrate stratum corneum with feeding tube and inject digestive enzymes that allow digest tissue consume up then drop down from host and continue mature nymph and adult stages (8 legs)

3. Nummular dermatitis. Nummular dermatitis is a chronic inflammatory skin disease characterized by multiple, pruritic, coin-shaped eczematous lesions involving the extremities and the trunk. Nummular dermatitis is often considered to be a form of idiopathic eczema. It is usually seen in females over the age of 50. Numerous factors have been known to cause this condition such as decreased cutaneous lipid production, staphylococcus infections, allergy to metals, and sensitivity to yeast and dust mites. Patients with this condition present with highly pruritic, round, coin-shaped patches of eczematous dermatitis ranging in diameter from 1 to 10 cm. The legs and the upper extremities are the sites most frequently involved and the trunk is less

Mites survive by eating human’s dandruff and scalp. They are mainly parasites that stay in the mattress, or any other places that are warm or dark for them to survive. While tidying up the bed sheet, the mites together with the dust are thrown away scattering around the floor, primarily in the bedroom. However, mites do not prefer to sit on carpet or floor that is not their ideal survival environment as it is too cold, too dry or too expose to the light, and sometimes may be cleaned away by the detergents. They may also wipe off by the mop, floor or even be removed away by the vacuum cleaner. Therefore, they select human’s body as their ideal habitats.

Scabies is a skin disease caused by an infestation of an itch mite in the human skin. the mites burrow into the dermis and lay eggs. The condition is transmitted by direct, prolonged, skin-to-skin contact with someone who has scabies. The most common places to find people who have contracted scabies are places such as nursing homes, extended care facilities, and daycares. Most people infected with scabies house 10-15 mites during their period of infestation. However, some special cases, known as crusted scabies, can house over 1000 mites at one time. These mites burrow into their host’s skin to feed and live, but they can survive 48-72 without human contact.

Human scabies is caused by an infestation of the skin by the human itch mite. The itch mite is so small it is hard to distinguish with the human eye. The scabies mite burrows in the upper layer of the skin where it lives and lays its eggs. Scabies is transmitted by prolonged skin-to-skin contact. The most common symptoms are intense itching and a pimple like rash. Scabies undergo four stages in their life cycle: egg, larvae, nymph, and adult scabies. The eggs are 0.10 to 0.15 mm in length. They hatch 3 to 4 days after they are laid. After they hatch, the larvae work their way to the skin’s surface and burrow into the stratum corneum creating molting pouches. As the larval stage begins, the larvae only have three legs. This stage lasts 3 to

-Insects go through discontinuous gas exchange (DGE). This means they are not exchanging gas with the environment when at rest.

Mites of all stages of life have been observed to dig burrows into and through the stratum corneum near the stratum corneum/stratum lucidum interface with female mites observed to burrow into the stratum granulosum of hosts (Fischer et al. 2012; McCarthy et al. 2004). S.scabiei derive water and nutrition from the serum that seeps into the burrow created by the mite as well as from the nutrients gained from the digestion of living cells in or near the stratum

Cat scratch disease (CSD), also known as subacute regional lymphadenitis or cat scratch fever, is a common bacterial infection caused by Bartonella henselae. As one may deduce, infected cats are disease vectors and transmit the bacteria, which is found in their saliva via bites or scratches. It is estimated that up to 50 percent of cats may be carriers of the microorganism responsible for CSD and these cats may show no signs of infection. Occasionally, fleas, which are responsible for spreading the infection from one cat to another may also transmit the disease to people. In addition to fleas, bites from infected ticks may also lead to disease transmission.

Anthrax is a disease caused by a bacterium called Bacillus anthracis. It all started out when Robert Koch first discovered the bacterium that caused Anthrax. Not only does anthrax effect animals but also humans as well. In the United States on 2001, it was reported that there were bioterrorist attacks happening throughout the country. Many believed it was a bioterrorist attack from letters being delivered in the mail that contain anthrax spores. The types of anthrax, causes, signs and symptoms, diagnosis and the treatment is what makes anthrax one of the viral diseases in the world.

Most rashes are from one source: dermatitis. Dermatitis is a condition that occurs when your skin comes in contact with things that you are allergic to, or things that irritate your skin. Dermatitis causes your skin to become inflamed, which usually leads to a rash. Most rashes are itchy, they cause your skin to be dry, and they make your skin look red and irritated. While rashes are rarely contagious to people you come in contact with, it will certainly make people want to stay far, far away from you, or at least to not come in direct contact with your skin. What could be worse than being miserable and your friends and family steering clear of
