Biocide tolerance in bacteria

Area of Science:

• Microbiology
• Molecular Biology
• Food Safety

Background:

• Biocides have long been used for antimicrobial purposes, with a wide array of compounds available.
• Emerging bacterial tolerance to biocides necessitates understanding their mechanisms of action.
• A potential link between biocide tolerance and antibiotic resistance is a growing concern.

Purpose of the Study:

• To review advances in understanding biocide mechanisms of action.
• To explore bacterial resistance mechanisms to both biocides and antibiotics.
• To assess the prevalence of biocide tolerance in bacteria relevant to human health and the food industry.

Main Methods:

• Literature review of scientific articles.
• Analysis of molecular mechanisms of resistance.
• Examination of bacterial tolerance data.

Main Results:

• Biocide action mechanisms are diverse.
• Efflux systems can confer broad tolerance to unrelated antimicrobials, including antibiotics and biocides.
• Biocide tolerance is observed in bacteria relevant to human health and food safety.

Conclusions:

• Understanding biocide and antibiotic resistance mechanisms at the molecular level is vital for detection and monitoring.
• The spread of resistance determinants can lead to new resistant microorganisms.
• Addressing biocide tolerance is critical for public health and food security.
