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.
At their root are fungi, not the bacteria or viruses that cause other infections. Technically speaking, ringworm is a dermatophyte, says Weinberg. A dermatophyte is simply a type of fungi that can cause skin, hair, or nail infections. Candida is a yeast, says Weinberg. These fungi can cause infections on many areas of the body. These fungal infections affect some of the same body parts but also different ones, Stein Gold tells WebMD.
