Abstract
The biological activity and mechanisms of action of the unsaturated ketone β-ionone, a volatile compound of serious interest for biotechnology, medicine, and agriculture, have been studied. Using specific lux-biosensors based on Escherichia coli MG1655, we found that β-ionone causes oxidative stress in E. coli cells by inducing expression from the PkatG and Pdps promoters, but not from PsoxS promoter. The effects of β-ionone on the induction of heat shock (expression from PibpA and PgrpE promoters) in E. coli cells were significantly weaker as well as its ability to cause DNA damage (expression from PcolD and PdinI promoters, SOS response). β-Ionone did not cause oxidative stress in the cells of the gram-positive bacterium Bacillus subtilis.

Abstract
A total of 397 strains of Mycobacterium tuberculosis isolated from newly diagnosed patients with pulmonary tuberculosis in the Omsk oblast in 2019–2020 were genotyped. The prevalence of the Beijing genotype strains (70.8%), in particular, of two modern sublineage clusters: Central Asian/Russian (46.1%) and B0/W148 (19.1%), was established. Strains of the ancient sublineage of the Beijing genotype were represented by clusters 1071-32 and 14717-15, totaling 4.8%. Compared with other genotypes, the strains of B0/W148-cluster and the ancient Beijing sublineage were more often characterized by multidrug resistance (MDR): 93.4 and 94.7%, respectively (P < 0.0001). Among members of other genetic families (LAM, Ural, T, Haarlem), drug-sensitive strains predominated (75.0%). The circulation of MDR Beijing strains requires molecular epidemiological surveillance in view of their possible wider spread.
