Abstract:
There is almost a century since discovery of penicillin by Alexander Fleming, a century of enthusiasm, abuse, facing development of antibiotic-resistance and clear conclusion that the modern medicine needs a new type of antimicrobials. Bacteriocins produced by Gram-positive and Gram-negative bacteria, Archaea and Eukaryotes were widely explored as potential antimicrobials with several applications in food industry. In last two decades bacteriocins showed their potential as promising alternative therapeutic for the treatment of antibiotic-resistant pathogens. Bacteriocins can be characterised as highly selective antimicrobials and therapeutics with low cytotoxicity. Most probably in order to solve the problems associated with the increasing number of antibiotic-resistant bacteria, the application of natural or bioengineered bacteriocins in addition to synergistically acting preparations of bacteriocins and conventional antibiotics, can be the next step in combat versus drug-resistant pathogens. In this overview we focussed on diversity of specific lactic acid bacteria and their bacteriocins. Moreover, some additional examples of bacteriocins from non-lactic acid, Gram-positive and Gram-negative bacteria, Archaea and eukaryotic organisms are presented and discussed. Therapeutic properties of bacteriocins, their bioengineering and combined applications, together with conventional antibiotics, were evaluated with the scope of application in human and veterinary medicine for combating (multi-)drug-resistant pathogens.
Insights
Bacteriocins, antimicrobial peptides, offer a promising alternative to traditional antibiotics for combating drug-resistant pathogens. Their selective nature and low cytotoxicity make them valuable for human and veterinary medicine.
Area of Science:
- Microbiology
- Biotechnology
- Pharmacology
Background:
- The discovery of penicillin nearly a century ago marked a milestone, but widespread antibiotic resistance necessitates novel antimicrobial strategies.
- Bacteriocins, antimicrobial peptides produced by various organisms, have shown potential as food preservatives and, more recently, as therapeutics.
- The rise of antibiotic-resistant bacteria highlights the urgent need for alternative treatments in modern medicine.
Purpose of the Study:
- To review the diversity of bacteriocins, focusing on those from lactic acid bacteria.
- To explore the potential of bacteriocins as alternative therapeutics against antibiotic-resistant pathogens.
- To evaluate bioengineered bacteriocins and their combined use with conventional antibiotics.
Main Methods:
- Literature review of bacteriocins from lactic acid bacteria, non-lactic acid bacteria, Archaea, and Eukaryotes.
- Analysis of bacteriocin characteristics, including selectivity and cytotoxicity.
- Evaluation of therapeutic applications, bioengineering, and synergistic combinations with antibiotics.
Main Results:
- Bacteriocins exhibit high selectivity and low cytotoxicity, making them suitable for therapeutic use.
- Diverse bacteriocins from various microbial sources show promise against resistant pathogens.
- Bioengineered bacteriocins and combinations with existing antibiotics offer enhanced antimicrobial strategies.
Conclusions:
- Bacteriocins represent a viable alternative to conventional antibiotics for combating multidrug-resistant pathogens.
- The application of bacteriocins in human and veterinary medicine is a promising next step in antimicrobial therapy.
- Further research into bacteriocin bioengineering and synergistic applications will enhance their therapeutic efficacy.
