Within the frames of activities attributed to the Reference Center for tularemia monitoring at SRC AMB, genetically identified are 4 isolates of Francisella tularensis , isolated in 2011 in the Altai Territory. These bacteria prove to be virulent for BALB/c mice, DCL being lower than 10 CFU. Using single-primer PCR-typing and MLVA assay distinguished have been the subspecies of the isolates. Three of them refer to the Central Asian subspecies, one – to the Holarctic, the former being isolated in the territory of the Russian Federation for the first time ever.
