Проведен анализ антибиотикорезистентности коллекционных и выделенных из самоквасных молочных продуктов штаммов молочнокислых бактерий родов Lactococcus, Enterococcus, Leuconostoc. Выявлена схожесть фенотипических профилей антибиотикоустойчивости у энтерококков и лактококков. Установлено, что коллекционные штаммы L. lactis устойчивы к более широкому спектру антибиотиков по сравнению со штаммами, выделенными из самоквасных молочных продуктов. Показано, что фенотипическая устойчивость молочнокислых бактерий к антибиотикам не всегда коррелирует с наличием трансмиссивных генетических детерминант антибиотикорезистентности, поэтому необходимо проводить мониторинг данного признака на фенотипическом и генетическом уровнях.

Analysis of antibiotic resistance of collection and isolated from homemade dairy products strains of lactic acid bacteria belonging to genera Lactococcus, Enterococcus, Leuconostoc was performed. Similarity of phenotypic profiles of antibiotic resistance of lactococci and enterococci was established. It was shown, that collection strains L. lactis possess resistance to broader spectrum of antibiotics as compared to strains, isolated from homemade dairy products. Phenotypic resistance to antibiotics does not always correlate with presence of genetic determinants of antibiotic resistance, thus monitoring of this feature should be performed both on phenotypic and genotypic levels.
