Burkholderia thailandensis

Burkholderia thailandensis is a nonfermenting motile, Gram-negative bacillus that occurs naturally in soil. It is closely related to Burkholderia pseudomallei, but unlike B. pseudomallei, it only rarely causes disease in humans or animals.[2][3][4][5] The lethal inoculum is approximately 1000 times higher than for B. pseudomallei.[6] It is usually distinguished from B. pseudomallei by its ability to assimilate arabinose.[7] Other differences between these species include lipopolysaccharide composition, colony morphology, and differences in metabolism.[8]

Use in research

B. thailandensis is sometimes used to model B. pseudomallei infection in mice because of similarities in the immune response.[9][10][11] B. thailandensis does not require biosafety category 3 facilities and is not considered a biosecurity threat, which makes it easier to study and to work with.[12]

Small RNA

Research suggests that as in other bacteria, small non coding RNAs play a role in response to the environmental and stress conditions like antibiotic exposure and survival in a host-specific environment.[13] Several small RNA have been discovered in B. thailandenisis: BHT_s1 and BHT_s39 exhibit differential expression profiles dependent on growth phase and cell stimuli, such as antibiotics and serum. BHT_s39 could function in bacterial metabolism and adaptation to host. BTH_s13 and BTH_s19 may regulate expression of their downstream gene.[13]
