STUDY OF ANTIBACTERIAL ACTIVITY OF THE PREPARATIONS WITH DIOXIDINE AND LEVOFLOXACIN ON MAIN PURULENT-INFLAMMATORY PROCESSES PATHOGENS.

OBJECTIVE

The aim: Study of antibacterial activity of the preparations, containing antiseptic dioxidine and antibiotic levofloxacin in vitro on standard strains of main optional-anaerobic pathogens of purulent-inflammatory processes of surgical wounds S. aureus, E. coli, P. aeruginosa and definition of more effective ones on them.

PATIENTS AND METHODS

Materials and methods: Solutions of dioxidine 1.2 %, dioxidine 1.2% with decamethaxin, Dioxisole, water soluble ointment with dioxidine 1.2% and levofloxacin 0.1% with decamethaxin were used in experiment. Antibacterial activity was studied on standard strains of S. aureus АТСС 25923, E. coli АТСС 25922, P. aeruginosa АТСС 27853. Distinguishing and identification of pure cultures of bacteria was done according to generally accepted microbiological methods. Determination of purulent-inflammatory processes pathogens sensitivity was done by disco-diffuse method on Mueller-Hinton medium. Antibacterial activity of solutions and ointments was studied with the help of agar diffusion method ("well" method) according to methodic recommendations. Each investigation was repeated 6 times. Method of variation statistics was used for the research results analysis.

RESULTS

Results: All antibacterial preparations under study are effective and highly effective on S. aureus АТСС 25923, E. coli АТСС 25922, P. aeruginosa АТСС 27853. Solution with 1.2 % dioxidine with decamethaxin and ointment with 0.1 % levofloxacin and decamethaxin have larger growth retardation zones towards S. aureus and P. aeruginosa. E. coli strains are more sensitive to the solution of Dioxisole and ointment with 1.2 % dioxidine.

CONCLUSION

Conclusions: All strains are sensitive, most of them are highly sensitive, up to 5 antibacterial preparations under study in vitro.
