During a year of screening DNA samples from more than 400 families with bipolar disorder, the study's first author, Thomas B. Barrett, M.D., Ph.D., assistant professor of psychiatry, UCSD and psychiatrist, San Diego VA Healthcare System, determined that there were six mutations in the promoter region of the GRK3 gene.
Dermatophytes are fungi that require keratin for growth. These fungi can cause superficial infections of the skin, hair, and nails. Dermatophytes are spread by direct contact from other people (anthropophilic organisms), animals (zoophilic organisms), and soil (geophilic organisms), as well as indirectly from fomites.ransmission of dermatophytes also can occur indirectly from fomites (e.g., upholstery, hairbrushes, hats). Anthropophilic organisms are responsible for most fungal skin infections. Transmission can occur by direct contact or from exposure to desquamated cells.
Dermatophytes cause infections of the skin, hair and nails, obtaining nutrients from keratinized material. The organisms colonize the keratin tissues causing inflammation as the host responds to metabolic by-products.ermatophytes are transmitted by direct contact with infected host (human or animal) or by direct or indirect contact with infected exfoliated skin or hair in clothing, combs, hair brushes, theatre seats, caps, furniture, bed linens, shoes, socks, towels, hotel rugs, sauna, bathhouse, and locker room floors.
