Dermatophytosis. Dermatophytosis, also known as tinea and ringworm, is a fungal infection of the skin [2] (a dermatomycosis), that may affect skin, hair, and nails. [1] Typically it results in a red, itchy, scaly, circular rash. [1] Hair loss may occur in the area affected. [1] Symptoms begin four to fourteen days after exposure. [1]
Tinea corporis. This patient presented with ringworm on the arm, or tinea corporis due to Trichophyton mentagrophytes. Tinea corporis is a fungal infection of the body, similar to other forms of tinea. Specifically, it is a type of dermatophytosis (or ringworm) that appears on the arms and legs, especially on glabrous skin; however, it may ...
Some of these skin infections are known as ringworm or tinea (which is the Latin word for "worm"), though infections are not caused by worms. [3] [7] It is thought that the word tinea (worm) is used to describe the snake-like appearance of the dermatophyte on the skin. [7] Toenail and fingernail infections are referred to as onychomycosis ...
The disease is infectious and can be transmitted by humans, animals, or objects that harbor the fungus. The fungus can also exist in a carrier state on the scalp, without clinical symptomatology. Treatment of tinea capitis requires an oral antifungal agent ; griseofulvin is the most commonly used drug, but other newer antimycotic drugs, such as ...
Microsporum audouinii var. canis E.Bodin (1900) Sabouraudites canis (E.Bodin) Langeron (1945) Microsporum canis is a pathogenic, asexual fungus in the phylum Ascomycota that infects the upper, dead layers of skin on domesticated cats, and occasionally dogs and humans. [1][2] The species has a worldwide distribution. [3]
The fungi tend to spread to areas of skin that are kept warm and moist, such as with insulation (clothes), body heat, and sweat. However, the spread of the infection is not limited to skin. Toe nails become infected with fungi in the same way as the rest of the foot, typically by being trapped with fungi in the warm, dark, moist inside of a shoe.
Tinea cruris (TC), also known as jock itch, is a common type of contagious, superficial fungal infection of the groin and buttocks region, which occurs predominantly but not exclusively in men and in hot-humid climates. [3][4] Typically, over the upper inner thighs, there is an intensely itchy red raised rash with a scaly well-defined curved ...
Microsporum is a genus of fungi that causes tinea capitis, tinea corporis, ringworm, and other dermatophytoses (fungal infections of the skin). Microsporum forms both macroconidia (large asexual reproductive structures) and microconidia (smaller asexual reproductive structures) on short conidiophores. Macroconidia are hyaline, multiseptate ...
