Amphotericin B was given at 1 mg/kg/day. Itraconazole was given at 50 mg/kg BID. Posaconazole was given at 5, 25, or 40 mg/kg/day. Controls received either 5% glucose intraperitoneally (i.p.) or methylcellulose per os (p.o.) by gavage.
Data from both control groups were pooled before statistical analysis.
The brain from one mouse was not tested.
