Little is known about the biogeography of this bacterium in Australia, despite its hyperendemicity in the northern region of this continent. The population structure of 953 Australian\n            <jats:named-content content-type=\"genus-species\">B. pseudomallei<\/jats:named-content>\n            strains representing 779 and 174 isolates of clinical and environmental origins, respectively, was analyzed using multilocus sequence typing (MLST). Bayesian population structure and network SplitsTree analyses were performed on concatenated MLST loci, and sequence type (ST) diversity and evenness were examined using Simpson's and Pielou's indices and a multivariate dissimilarity matrix. Bayesian analysis found two\n            <jats:named-content content-type=\"genus-species\">B. pseudomallei<\/jats:named-content>\n            populations in Australia that were geographically distinct; isolates from the Northern Territory were grouped mainly into the first population, whereas the majority of isolates from Queensland were grouped in a second population. Differences in ST evenness were observed between sampling areas, confirming that\n            <jats:named-content content-type=\"genus-species\">B. pseudomallei<\/jats:named-content>\n            is widespread and established across northern Australia, with a large number of fragmented habitats. ST analysis showed that\n            <jats:named-content content-type=\"genus-species\">B. pseudomallei<\/jats:named-content>\n            populations diversified as the sampling area increased. This observation was in contrast to smaller sampling areas where a few STs predominated, suggesting that\n            <jats:named-content content-type=\"genus-species\">B. pseudomallei<\/jats:named-content>\n            populations are ecologically established and not frequently dispersed.
