Differences in MICFAST were observed between colony variants of K. pneumoniae isolate K16. When subculturing IMP-4 producing K. pneumoniae isolate K16, a rough and smooth colony variant was observed. The smooth colony variant produced an MICFAST of 2 mg/L. The rough colony produced an MICFAST of 64 mg/L and, at 2 mg/L, was observed by AFC to contain a population consistent with a non-susceptible phenotype. Both MICFAST results were concordant with the MICBMD results.
