| Summary: | Objective.
To evaluate the ability of bovhyaluronidaze azoximer to destroy biofilms formed by clinical strains of microorganisms.
Materials and Methods.
The study included 50 clinical strains of Staphylococcus aureus (n = 25), Staphylococcus epidermidis (n = 6), Enterococcus faecalis (n = 8), Escherichia coli (n = 9), Candida albicans (n = 2). Antimicrobial susceptibility testing was performed using broth microdilution method. Biofilm formation culturing in presence of antibiotics, or bovhyaluronidaze azoximer, or their combinations was assessed in Mueller-Hinton broth and brain heart broth in 96-well plates. Biofilms were fixed with 2,5% glutaraldehyde solution, stained with 0,25% crystal violet solution, which is extracted by 33% acetic acid solution.
Results.
Bovhyaluronidaze azoximer can destroy the matrix of preformed biofilms of methicillin-resistant strains of S. aureus as well as S. epidermidis, E. coli, C. albicans in concentrations of 64–1000 IU/ml, while exerting a dose-depend effective.
Conclusions.
Bovhyaluronidaze azoximer combining with antibiotics will potentiate its antimicrobial effects by destroying the microbial biofilm matrix formed by microorganisms with multidrug resistance and facilitating the penetration of antibiotics to cellular targets. |
