Kodamaea ohmeri and Prototheca wickerhamiiare rare pathogens for humans, and even morerare as cause of onychomycosis. This work reports thesecond case of onychomycosis by K. ohmeri and thefourth of onycoprotothecosis; it was made in publichealth institutions in the Hidalgo State, Mexico,studying 261 diabetic patients during 2005 and 2006.Kodamaea ohmeri was isolated from toenails of a51-year-old female patient, and P. wickerhamii fromthree female patients of 48, 49, and 61 years old,respectively, all of them with type 2 diabetes mellitus(DM 2). Identifications were done by standardmicrobiological methods and a commercial system.Only one patient infected with P. wickerhamii showedmixed infection with dermatophytes. Out of the totalstudied DM 2 patients, 1.15% presented onycoprotothecosisand 0.38% onychomycosis by K. ohmeri, highpercentages if it is considered that few cases have beenreported of K. ohmeri and P. wickerhamii as onychomycosiscausal agents.
