Urinary tract infection by Trichosporon asahii.

Trichosporon asahii is a basidiomycetous yeast which causes white piedra and onychomycosis in immunocompetent hosts as well as various localized and disseminated invasive infections in immunodeficient hosts. Urinary tract infection caused by Trichosporon asahii is rare. One month after posterior urethral valve surgery a seven-month-old male child presented with fever, severe vomiting and crying on micturition for five--to six days. Yeast-like fungus was isolated in pure cultures from three consecutive urine samples. It was identified as Trichosporon asahii using standard techniques. The response to antifungal therapy was dramatic. To the best of our knowledge this is the first report of a urinary tract infection caused by Trichosporon asahii from Western India.
