TABLE 2.

Comparison of antifungal susceptibilities of blood isolates of C. lusitaniae prior to and during amphotericin B treatment^a

Drug	Prior to amphotericin B treatment		During amphotericin B treatment
	MIC (μg/ml)	Interpretation	MIC (μg/ml)	Interpretation
Amphotericin B	0.25	Sb	1.0	S
Fluconazole	1.0	S	1.0	S
Itraconazole	<0.5	S	<0.5	S

^aThese results were reported by a reference laboratory using the NCCLS macrodilution reference standard methodology, which was different from the in-house testing procedure used for the comparison represented in Table 3. The inoculum used by the reference laboratory originated from a random selection of colonies without regard to colony color on CAC.

^bS, susceptible.
