^a Only provinces with n ≥ 12 were selected to calculate diversity indices (Na, A and H_E).

^b N, number of isolates per province.

^c Na, number of alleles.

^d A, allelic richness calculated by rarefaction method (n = 12).

^e N_H, number of haplotypes in each province.

^f H_E, Nei’s genetic diversity within provinces.

^g H_T, total Nei’s genetic diversity.
