title: [Contribution of determinants, located in Bacillus anthracis chromosomes, in realizing the pathogenic properties of the pathogen].
abstract: Comparative study of virulence of B. anthracis strains harbouring pXO1 and pXO2 plasmids in mice and guinea pigs showed that among six B. anthracis strains, three were 100-1000 times less virulent for guinea pigs. Genetic construction of B. anthracis strains using transduction and conjugation transfer of resident plasmids permitted us to rule out the effects of modified pXO1 and pXO2 replicons and to prove the existence of nonidentified chromosome locuses responsible for the development of an infectious process in anthrax, along with plasmid determinants of virulence.
