В данной работе было изучено сочетанное влияние озонида (озонированная среда) и антибиотиков на бактерии Escherichia coli, и Staphylococcus aureus. В эксперименте использовали антибиотики различных классов (канамицин, эритромицин, бензилпенициллин, цефтриаксон и цефазолин), имеющих разные механизмы повреждающего действия на бактериальные клетки. Интерес к изучению сочетанного влияния озонида и антибиотиков на бактерии основывался на данных литературы и собственных результатах, полученных ранее. Для этой серии экспериментов мы выбрали концентрацию озонида, не вызывающую гибель бактериальных клеток – 0,35-0,57 мкг/мл. Концентрация антибиотиков составляла 10⁻⁴–10⁻² г/мл. При инкубировании с озонидом минимальная бактериальная концентрация антибиотиков повышалась, соответственно от 10⁻³ до 10⁻¹ г/мл. При изучении сочетанного воздействия антибиотиков и озонида на бактерии, установлено, что озонид частично инактивирует антибиотики, при этом минимальная бактерицидная концентрация антибиотиков повышается в среднем на один порядок.
The combined influence of ozonide (the ozonized growth medium) and antibiotics on the bacteria of Escherichia coli and Staphylococcus aureus was studied in this work. Antibiotics of various classes (kanamycin, erythromycin, benzylpenicillin, ceftriaxone and cefazolin) having different mechanisms of damaging effects on bacterial cells were used in the experiment. Interest in studying the combined effect of ozonide and antibiotics on the bacteria was based on the literature data and own results obtained earlier. The optimal concentration of ozonide (0,35–0,57 мкг/мл) which was not causing death of bacterial cells has been chosen for this series of experiments. The increase in the proliferative activity of microorganisms under the ozone influence can be used for biomass increase and biologically active substances producing increase. The concentration of antibiotics was ranged from 10⁻⁴–10⁻² g/ml. When incubated with ozonide, the minimum bacterial concentration of antibiotics was increased, respectively from 10⁻³ to 10⁻¹ g/ml. When studying the combined effect of antibiotics and ozonide on the bacteria, it was found that ozonide partially inactivated antibiotics, while the minimum bactericidal concentration of antibiotics increased by an average on one order value. The inhibiting effect of ozonide on the bactericidal properties of antibiotics must be considered in the development of ozonation schemes for the inactivation of pathogenic microorganisms that cause of biological material contamination.
