C. albicans isolates and their PNG2 repeat region size combinations.

aSee [23] for more detail on isolates.bA, B and C are the three major jackknifing-supported branches within the species, with limited support for a further subdivision of the general-purpose genotype A into two groups A1 and A2, based on Ca3 fingerprints [23]; for strains in brackets other markers are in conflict with the Ca3-based classification [6].cStrains were isolated from: anal sites (a), catheter (c), respiratory and oral sites (r/o), skin and wounds (s/w), sterile sites (s), urine (u), vagina/vulva (v).dNumber of repeat units in both alleles based on length of PCR products (and for some strains also by sequencing; see Fig. 5); where only one product was detected it was assumed that the isolate possessed two identical-sized repeat units.eBased on [30].
