title: Uncommon fungi isolated from diabetic patients toenails with or without visible onychomycoses.
abstract: Kodamaea ohmeri and Prototheca wickerhamii are rare pathogens for humans, and even more rare as cause of onychomycosis. This work reports the second case of onychomycosis by K. ohmeri and the fourth of onycoprotothecosis; it was made in public health institutions in the Hidalgo State, Mexico, studying 261 diabetic patients during 2005 and 2006. Kodamaea ohmeri was isolated from toenails of a 51-year-old female patient, and P. wickerhamii from three female patients of 48, 49, and 61 years old, respectively, all of them with type 2 diabetes mellitus (DM 2). Identifications were done by standard microbiological methods and a commercial system. Only one patient infected with P. wickerhamii showed mixed infection with dermatophytes. Out of the total studied DM 2 patients, 1.15% presented onycoprotothecosis and 0.38% onychomycosis by K. ohmeri, high percentages if it is considered that few cases have been reported of K. ohmeri and P. wickerhamii as onychomycosis causal agents.
