The efficacies of colicins E1 and N against Escherichia coli strains responsible for postweaning diarrhea and edema disease, two of the most prevalent disease problems for pigs in the United States, were determined in vitro. These proteins may provide an environmentally sound means for the prevention of these infections in swine.

Antimicrobial-resistant (AMR) pathogens represent a serious threat to public health, particularly in food production systems where antibiotic use remains widespread. As a result, alternative antimicrobial treatments to antibiotics are essential for effectively managing bacterial infections. This study aimed to identify and characterize novel antimicrobial peptides produced by bacteria, known as bacteriocins, as well as to recognize safe bacteriocin-producing strains, sourced from poultry slaughterhouse effluents.

Rationale: Plasmids can play a major role in the survival of pathogenic bacteria. Plasmids are acquired through horizontal gene transfer resulting in their spread across various strains, species and genera of bacteria. Colicins are bacterial protein toxins expressed by plasmid genes and released against co-located bacterial competitors.

Previous work shows that a host's resident microbial community can provide resistance against an invading pathogen. However, this community is continuously changing over time due to adaptive mutations, and how these changes affect the invasion resistance of these communities remains poorly understood. To address this knowledge gap, we used an experimental evolution approach in synthetic communities of Escherichia coli and Salmonella Typhimurium to investigate how the invasion resistance of this community against a bacterium expressing a virulent phenotype, i.

Unlabelled: This work presents a multi-hurdle approach that addresses antimicrobial resistance by minimizing the selective pressure of antimicrobials using a novel colicinogenic-phage system. We have created two synthetic T7 phages (T7-E1 and T7-M) by inserting the gene of colicin E1 (Cea) or colicin M (Cma) into the genome of the T7 phage, thereby adding an additional colicin-based hurdle to the T7 lytic cycle. The colicin-phages' efficacy in suppressing the outgrowth of a T7-resistant sub-population within a mixed culture of was demonstrated using a challenge matrix design under planktonic and structured conditions.

Colicins are antimicrobial proteins produced by certain strains of that function as offensive weapons against closely-related competitor strains. Their bactericidal properties and narrow bacterial targeting range has made them of therapeutic interest. Furthermore, the applications of engineered non-bactericidal colicins are of interest as a cell surface-directed protein anchor for decorating with biomolecules.
