Tinea corporis (also known as "ringworm", [2] tinea circinata, [11] and tinea glabrosa [2]) is a superficial fungal infection (dermatophytosis) of the arms and legs, especially on glabrous skin; however, it may occur on any part of the body, it present as annular, marginated plaque with thin scale and clear center.
Superficial scrapes of skin examined underneath a microscope may reveal the presence of a fungus.This is done by utilizing a diagnostic method called KOH test, [6] wherein the skin scrapings are placed on a slide and immersed on a dropful of potassium hydroxide solution to dissolve the keratin on the skin scrappings thus leaving fungal elements such as hyphae, septate or yeast cells viewable.
One of the most frequent forms is dermatophytosis (ringworm, tinea) which includes tinea pedis, also known as athlete's foot. Another example is cutaneous candidiasis. These fungal infections impair superficial layers of the skin, hair and nails. [1] Dermatomycosis is one of the most common types of infection worldwide. [2]
Microsporum audouinii causes the infections Tinea capitis (scalp ringworm) and Tinea corporis. [2] These superficial dermal diseases are generally found in prepubescent children (starting at 6 months) and rarely affect adults. [3] There are a few reasons why children are more susceptible to M. audouinii.
Trichophyton rubrum is a dermatophytic fungus in the phylum Ascomycota.It is an exclusively clonal, [2] anthropophilic saprotroph that colonizes the upper layers of dead skin, and is the most common cause of athlete's foot, fungal infection of nail, jock itch, and ringworm worldwide. [3]
Tinea faciei is a fungal infection of the skin of the face. [1] It generally appears as a photosensitive painless red rash with small bumps and a raised edge appearing to grow outwards, usually over eyebrows or one side of the face. [1] It may feel wet or have some crusting, and overlying hairs may fall out easily. [2] There may be a mild itch. [3]
Microsporum gallinae is a fungus of the genus Microsporum that causes dermatophytosis, commonly known as ringworm. [1] Chickens represent the host population of Microsporum gallinae but its opportunistic nature allows it to enter other populations of fowl, mice, squirrels, cats, [2] dogs and monkeys. [3]
