We studied the recovery of 1,270 fungal isolates from 176,144 Isolator bloo
d cultures (0.72% positive) on bacterial and fungal media, under routine an
d differing incubation conditions. Except with Histoplasma capsulatum, choc
olate agar incubated for only 3 days proved to be an excellent medium for t
he recovery of fungi from the Isolator system.
