Gram-negative toe web infections can be a distressing and at times disabling disorder, with the threat of sepsis possible in neglected or predisposed individuals. The cause may be multifactoral, with overgrowth of Gram-negative organisms between the toes associated with marked hyperhidrosis, which may predispose the infection. Likewise, constant wearing of closed shoes so that the feet do not getmuch air circulation increases the chance of overgrowth of the microorganisms that create infections. Sporting activities increase the changes of interweb bacterial proliferation, especially with wet or water-related sports. In some patients this disorder may begin as a secondary infection of tinea pedis.
