  • a Results from two replicates and repeat testing. The numbers of isolates (n = 6) that resolved on repeat testing were as follows: C. albicans, 1; C. dubliniensis, 1; C. lambica, 1; C. lipolytica, 2; and C. nivariensis, 1.

  • b The numbers of isolates (n = 13) excluded from the study, as the isolates were not present in the Bruker library, were as follows: C. bracarensis, 1; C. sphaerica, 1; C. viswanathii, 1; Cr. bhutanensis, 1; Cr. gattii, 4; Geotrichum klebahnii, 1; Prototheca zopfii, 1; Kloeckera apis, 1; Nakaseomyces delphensis, 1; and P. salicaria, 1.
