Burkholderia, Burkholderia thailandensis Brett et al. 1998.
Old synonym: Burkholderia pseudomallei-like species.
Gram-negative rods. Non-spore-forming. Motile by a polar tuft of two to four flagella
Colonies are smooth and glossy with a pink pigmentation on modified Ashdown's
selective medium. Can grow at 25-42 ºC. Non-haemolytic. Can grow on MacConkey
agar. The production of siderophore, lipase, lecithinase and protease are apparent at
both 25 and 37 ºC.
Isolated from a rice field soil sample in central Thailand.
It is avirulent for Syrian golden hamsters. Studies describing the presence of B. thailandensis during epidemiological surveys in
Thailand have been unable to correlate human disease with this organism.
