In vitro antifungal-drug susceptibilities of mycelial and yeast forms of Penicillium marneffei isolates in Cambodia.

ABSTRACT

Penicillium marneffei infection is an important disease among human immunodeficiency virus patients in Southeast Asia. The in vitro antifungal-drug susceptibilities of 29 clinical isolates and 5 isolates from bamboo rats collected from 2002 to 2004 were determined. The P. marneffei yeast form is more susceptible than the mycelial form to amphotericin B and ketoconazole, while the mycelial and yeast forms displayed similar susceptibilities to flucytosine and itraconazole. The MICs of fluconazole were higher for both mycelial and yeast forms.
