aEach pair of primers consists of a forward and reverse primer which anneal to several positions in the C. glabrata genome and generate several amplicons
bThe size of the amplicons is calculated in silico with the sequence of the strain CBS138
cThe amplicon of the NE adjacent to EPA7 corresponds to the sequence from strain BG14 (GenBank Acc. No. AY646926.1)
dThe amplicon expected for C. glabrata is 878 bp, while the amplicons for C. parapsiolisis, C. tropicalis, and C. albicans are very similar (520 bp, 524, and 535 bp respectively)[25]
