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.
