Jh. Rex et al., DETECTION OF AMPHOTERICIN B-RESISTANT CANDIDA ISOLATES IN A BROTH-BASED SYSTEM, Antimicrobial agents and chemotherapy, 39(4), 1995, pp. 906-909
Because of the limited ability of the National Committee for Clinical
Laboratory Standards proposed M27P methodology to detect resistance to
amphotericin B by Candida isolates, we sought to identify alternative
media and pH conditions that could reliably identify resistant isolat
es. Antibiotic Medium 3 broth (also known as Penassay broth) buffered
to pH 5 or pH 7 produced superior results and readily identified a ser
ies of resistant isolates.
