Targeting Spore-Forming Bacteria: A Review on the Antimicrobial Potential of Selenium Nanoparticles

Area of Science:

• Microbiology
• Nanotechnology
• Food Science
• Healthcare

Background:

• Spore-forming bacteria (e.g., Bacillus, Clostridium) pose significant threats in food processing and healthcare due to their extreme resilience.
• Bacterial spores withstand harsh conditions, including high temperatures, radiation, chemicals, and antibiotics, complicating sterilization and disinfection efforts.
• Current sterilization methods face challenges against highly resistant bacterial spores, necessitating novel antimicrobial strategies.

Purpose of the Study:

• To review the antibacterial mechanisms of selenium nanoparticles (SeNPs) against spore-forming bacteria.
• To investigate the pathways of SeNP entry and their impact on bacterial spore formation and viability.
• To assess the efficacy of SeNPs in combating infections caused by spore-forming bacteria.

Main Methods:

• Literature review of studies investigating selenium nanoparticles and spore-forming bacteria.
• Analysis of proposed mechanisms of action for SeNPs against bacterial spores.
• Compilation of data on SeNP efficacy in various experimental models and applications.

Main Results:

• Selenium nanoparticles demonstrate potent antibacterial activity against spore-forming bacteria through multiple biological pathways.
• SeNPs can potentially inhibit spore formation and eliminate existing spores, offering a dual action.
• Evidence suggests SeNPs are effective against a range of bacterial infections, though mechanisms require further elucidation.

Conclusions:

• Selenium nanoparticles represent a promising antimicrobial agent for controlling spore-forming bacteria in food and healthcare settings.
• Understanding the precise mechanisms and factors influencing SeNP efficacy is crucial for developing targeted applications.
• Further research is essential to fully harness the potential of SeNPs in combating bacterial spore contamination and infections.
