Forty-six isolates of Candida parapsilosis, each from a single patient, were collected from July 1993 through March 1999 at the University of Ancona Hospitals and Clinics. Twenty-eight strains were isolated from superficial lesioned sites, including skin, nails and other sources while 18 strains were isolated from blood. The isolates were typed by electrophoretickaryotyping (EK) and tested for their susceptibility to fluconazole (FLC),itraconazole (ITC), flucytosine (5-FC), and amphotericin B (AMB). Ourdata confirmed that EK is a useful technique for DNA typing of isolates ofCandida parapsilosis and showed that the source of isolation is notassociated with a given DNA type. Although strains belonging to this speciesof Candida are susceptible to the most common antifungals, including the triazoles, the degree of ITC susceptibility was dose dependent (MIC rangingfrom 0.25–0.5 μg/ml) for 98% of the isolates. |
