In this study, it was demonstrated, by using agar diffusion tests and a Transwell system, that Burkholderia multivorans NKI379 has an antagonistic effect against the growth of B. pseudomallei. Bacterial representatives were isolated from agricultural crop soil and mixed to construct a partial bacterial community structure that was based on the results of reproducible patterns following PCR-denaturing gradient gel electrophoresis analysis of total soil chromosomes. The antagonistic effect of B. multivorans on B. pseudomallei was observed in this imitate community. In a field study of agricultural crop soil, the presence of B. pseudomallei was inversely relatedtothe presence of the antagonistic strains B. multivorans or B. cenocepacia. B. multivorans NKI379 can survive in a broader range of pH, temperatures and salt concentrations than B. pseudomallei, suggesting that B. multivorans can adapt to extreme environmental changes and therefore predominates over B. pseudomallei in natural environments.
