^aNumber of haplotypes/number of strains.

^bFifty-seven strains isolated in this study and the reference strain ICMP 11055, isolated in southern Iran in 1983.

^cNS, not significant.

^dNP, no polymorphism.

^eThe dnaK and rpoD gene sequences in strains ICMP 5752 and CIX127, respectively, were excluded from the analyses due to unsatisfactory sequence quality.
