Mixed Infection of Toe Nail Caused by Trichosporon asahii and Rhodotorula mucilaginosa
Mycopathologia(2019)
摘要
Trichosporon asahii and Rhodotorula mucilaginosa are important fungal species causing disseminated disease in immunocompromised patients. Onychomycosis prevalence rate ranges from 2 to 30%, which were 50% of nail diseases and 30% of superficial mycosis, respectively. Although important, little is known about the co-habitation of T. asahii and R. mucilaginosa in the causation of onychomycosis. Here, we present the co-habitation of T. asahii and R. mucilaginosa as causative agents of onychomycosis in a healthy 41-year-old male in China. Direct microscopic examination, fungal culture and MALDI-TOF MS were employed in isolated pathogens; hence, antifungal susceptibility test was evaluated. T. asahii was sensitive to posaconazole, voriconazole and itraconazole, whereas R. mucilaginosa was sensitive to both 5-flucytosine and amphotericin B. This report highlights the co-habitation of T. asahii and R. mucilaginosa in the causation of onychomycosis and to raise the awareness of this infection among dermatologists.
