[Burkholderia thailandensis: biological properties, identification and taxonomy].
Burkholderia pseudomallei-like microorganisms have been isolated from soil and water in regions with endemic melioidosis. These strains have biochemical and antigenic profiles identical to melioidosis agents, except that they differ by virulence and L-arabinose (vir-, ara+). There are minor differences between these species by rRNA sequence. DNA hybridization and, more so, positive transformation of DNA auxotrophic mutants of B. pseudomallei by cell lysates of B. thailandensis and B. mallei confirmed the homology of these species' genomes. These members of the Burkholderia genus (pseudomallei, mallei, and thailandensis) can be regarded as a supraspecies taxon: pseudomallei group. B. thailandensis strains are not virulent for guinea pigs and slightly virulent for golden hamsters. Immunization with live cultures of B. thailandensis protected more than 50% guinea pigs challenged with 200 LD50 B. pseudomallei 100. B. thailandensis is suggested as a potential melioidosis vaccine.
