a
Samples were categorized to the genotypic level (types 1 and 2) based on pSSU profiles and to the subgenotypic level (1A to 1K and 2A to 2I) based on pITS-2 profiles.
b
This sample (c35) from Cyprus differed slightly in profile from all other type 2 samples examined; this difference related to one A-to-T transversion in the pSSU sequence.
