title: [The sensitivity to antibiotics of biofilm cultures of toxigenic strains Corynebacterium diphtheriae].
abstract: The article presents analysis of sensitivity to antibacterial preparations of typical and biofilm culture of museum strain of Corynebacterium diphtheriae gravis tox+ SV-665. The strain was obtained from the L.A. Tarasevitch state research institute of standardization and control of medical biological preparations. The second strain C. diphtheriaecirculates gravis tox+ circulates in population of the Rostov oblast and it was recovered from patient with diagnosis of "localized form of diphtheria" by bacteriologic laboratory "1002 CGSEN SKVO" of Rostov-on-Don. The week and month biofilm cultures of both strains of C. diphtheriae gravis tox+ were used. The sensitivity to antibacterial preparations of typical and biofilm cultures of museum and circulating in population strains of agent of diphtheria were detected using minimal suppressing concentration by technique of serial dilutions in fluid growth medium. It is demonstrated that the most effective in respect of C. diphtheriae are such preparations as cefotaxinum, gentamycinum, lincomycin, canamycin and cefasolin. The sensitivity of pathogen in composition of biofilm to these preparations has no changes.
