[Antimicrobial and membranolytic activities of anti-burn drug fenozan]

Area of Science:

• Microbiology
• Dermatology
• Pharmacology

Background:

• Burn wounds are susceptible to bacterial infections, primarily by gram-positive bacteria.
• Antimicrobial agents are crucial for preventing and treating burn wound infections.
• Fenozan is an anti-burn preparation with potential antimicrobial properties.

Purpose of the Study:

• To investigate the antimicrobial activity of Fenozan against clinical and collection strains of gram-positive bacteria.
• To elucidate the mechanism of antimicrobial action of Fenozan.
• To evaluate the therapeutic potential of Fenozan in burn wound treatment.

Main Methods:

• Testing Fenozan's antimicrobial activity against Staphylococcus aureus and Streptococcus faecalis.
• Determining membranolytic and minimum inhibitory concentrations (MICs) of Fenozan.
• Comparing Fenozan's effects on bacterial cell membranes versus animal cell membranes.

Main Results:

• Fenozan exhibited antimicrobial activity against clinical strains of Staphylococcus aureus and Streptococcus faecalis, and other gram-positive bacteria.
• The antimicrobial action is attributed to impaired cytoplasmic membrane permeability, leading to the release of intracellular compounds.
• Fenozan's membranolytic and MICs were significantly lower than concentrations affecting animal cell membranes.

Conclusions:

• Fenozan possesses significant antimicrobial properties against relevant gram-positive pathogens.
• Its mechanism involves disruption of bacterial cell membrane integrity.
• The dual antioxidant and antimicrobial nature of Fenozan suggests its efficacy in treating burn wounds.
