  1. a, soil sample and culture data was obtained from our previous study [4]. The study reported the distribution of B. pseudomallei within an area of disused land in northeast Thailand and genotypes of primary plate colonies isolated from three independent sampling points (E4, D10 and A11).
  2. b, Out of a total of 200 colonies per sample.
  3. c, Inhibition effect of B. pseudomallei cell-free supernatant on five B. thailandensis isolates. The inhibition of B. thailandensis swarming was performed by the method (ii) assay. The table shows results of five B. thailandensis isolates which had the same results.
