                  Yersinia 
                  pestis 231 – проведено изучение образования биопленки на биотических поверхностях в условиях 
                  in 
                  vitro (на лабораторной модели нематоды 
                  С
                  aenorhabdiitis 
                  elegans) и 
                  in 
                  vivo (в пищеварительном тракте блохи 
                  Nosopsyllus 
                  laeviceps). Установлено, что причиной спонтанной потери способности к формированию биопленки и образованию пигментированных колоний может быть не только делеция всей хромосомной области пигментации, но и точечная мутация в структурном 
                  hms опероне. Показано, что отсутствие плазмид pCad, pFra или pPst не влияет на способность бесплазмидных мутантов формировать биопленку на кутикуле нематоды 
                  C. 
                  elegans.</p></abstract><trans-abstract xml:lang="en"><p>In non-pigmented and plasmid-deprived mutants – isogenic variants of highly virulent 
                  Yersinia pestis 231 strain – studied is the mechanism of biofilm formation on biotic surfaces, both 
                  in vitro (on the laboratory model of nematode 
                  Caenorhabdiitis elegans) and
                   in vivo (inside the alimentary tract of 
                  Nosopsyllus laeviceps flea). It is determined that spontaneous loss of ability to form biofilms and generate pigmented colonies in the mutants is probably caused not only by the deletion of the whole chromosome pigmentation fragment, but also by a point(single base) mutation in structural 
                  hms operon. It is demonstrated that the absence of 
                  pCad, pFra or
                   pPst plasmids does not have an impact on the ability of plasmid-deprived mutants to form biofilm on the cuticle of nematode
