Handling procedure
For freeze-dry (lyophilized) ampoules:
Open an ampoule according to enclosed instructions.
From a single test tube of sterile distilled water (5 to 6 mL), withdraw approximately 0.5 to 1.0 mL with a sterile pipette and apply directly to the pellet. Stir to form a suspension.
Aseptically transfer the suspension back into the test tube of sterile distilled water.
Let the test tube sit at room temperature for (25°C) undisturbed for at least 2 hours; longer (e.g., overnight) rehydration might increase viability of some fungi.
Mix the suspension well. Use several drops (or make dilutions if desired) to inoculate recommended solid or liquid medium.
Incubate the inoculum/strain at the temperature and conditions recommended.
Inspect for growth of the inoculum/strain regularly. The sign of viability is noticeable typically after 1-2 days of incubation. However, the time necessary for significant growth will vary from strain to strain.
Handling notes
In vitro susceptibility (MIC): 0.06 mg/L itraconazole; 2 mg/L fluconazole; 0.125 mg/L amphotericin B; the species is also known as Meyerozyma (= Pichia) guilliermondii.
