All isolates were from blood or normally sterile-site infections. All isolates were tested in RPMI 1640 broth with a 24-h incubation period and a prominent reduction endpoint criterion (MIC-2). Data are compiled from reference 224.
Eight of the 11 isolates for which the MICs were ≥2 μg/ml are glucan synthesis mutants.
