Auxarthron alboluteum related to non-dermatophytic toenail infection in Kurdistan region, Iraq: A case report

Abstract We report a rare case of non-dermatophytic onychomycosis of the big toenail caused by Auxarthron alboluteum in a 63-years old Iraqi female with a history of diabetes. The big toenail showed distal subungual onychomycosis with extensive yellow-white discoloration. Identification of the causative agent was confirmed by morphological and microscopical characteristics in culture and analysis of ITS-rDNA region. To the best of our knowledge, the isolated Auxarthron alboluteum reported here is a new etiologic species of nail infection in Iraq and this is the first case of its kind to be reported in the world.
