The values corresponding only to clinical strains of C. striatum are given within brackets

£ The number indicated the length of the sequenced fragment used for the polymorphic analysis

¥ The number of polymorphic sites, and the haplotype and nucleotide diversity was not calculated for the ITS1 region because in most cases more than one operon was detected. The number of alleles was established directly from the alignment
