Abstract

Using RT-PCR technique, the differences in cytokine genes expression in mice infected by Burkholderia pseudomallei
и B. thailandensis strains were investigated. The maximal mRNA level of IFN- γ and IL-12, belongs to Th1-type cytokine
profile of immune responce, was revealed in mice infected by avirulent B. thailandensis. The acute melioidosis caused by B. pseudomallei 100, contrastly, was characterized by termination of IFN- γ and IL-12 production and increase of IL-10 mRNA
quantity in latest stages of observation. The transcription profiles of cytokine genes in mice infected by attenuated mutant
B. pseudomallei 56770 99/10 was more related to case of B. thailandensis, however apparent similarity was matched in early stages of infection only. The obtained results demonstrate clear differences in immune response during infection
caused by B. pseudomallei and B. thailandensis, аnd a given approach may be useful to investigate the traits of Burkholderia
pathogenesis on molecular level.
