Use of the rapid diazonium blue B test to differentiate clinically important species of Trichosporon and Geotrichum.
Trichosporon isolates form pink to violet pigments following reaction with diazonium blue B which reliably differentiates them from Geotrichum species. The inoculum could be grown in static culture without diminishing the colour intensity. This modification facilitates use of the diazonium blue B reaction in clinical laboratories.
