Edward R. Winstead. A genome-wide search for susceptibility genes in bipolar disorder has yielded a potential hotspot on chromosome 22. In addition to the chromosome 22 region, researchers found evidence of susceptibility genes for bipolar disorder on chromosomes 3, 5, 10, 13 and 21.
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.hese fungi can cause superficial infections of the skin, hair, and nails.

The term  ringworm , commonly used to refer to such infections, is a misnomer, since the condition is caused by fungi of several different species and not by parasitic worms. The fungi that cause parasitic infection (dermatophytes) feed on keratin, the material found in the outer layer of skin, hair, and nails.These fungi thrive on warm and moist skin, but may also survive directly on the outsides of hair shafts or in their interiors.n pets, the fungus responsible for the disease survives in skin and on the outer surface of hairs. Currently, up to 20% of the population may be infected by dermatophytes at any given time. It is especially common among people who play sports involving skin-to-skin contact, wrestling in particular.
