Comparative analysis of effectiveness for phage cocktail development against multiple Salmonella serovars and its biofilm control activity.

Foodborne diseases are a major challenge in the global food industry, especially those caused by multidrug-resistant (MDR) bacteria. Bacteria capable of biofilm formation, in addition to MDR strains, reduce the treatment efficacy, posing a significant threat to bacterial control. Bacteriophages, which are viruses that infect and kill bacteria, are considered a promising alternative in combating MDR bacteria, both in human medicine and animal production.

Antibacterial Activity of Biodegradable Films Incorporated with Biologically-Synthesized Silver Nanoparticles and the Evaluation of Their Migration to Chicken Meat.

The food industry has been exploring the association of polymers with nanoparticles in packaging production, and active products are essential to increase the shelf life of food and avoid contamination. Our study developed starch-poly (adipate co-terephthalate butyl) films with silver nanoparticles produced with components (bio-AgNPs), intending to control foodborne pathogens. The bio-AgNPs showed activity against different serotypes, including multidrug-resistant Saint Paul and Enteritidis, with minimum bactericidal concentrations ranging from 4.

Antiphage activity of natural and synthetic substances: a new age for antivirals?

Viruses are considered biological entities that possess a genome and can adapt to the environment of living organisms. Since they are obligate intracellular parasites, their cycle of replication can result in cell death, and consequently, some viruses are harmful to mammalian cells and can cause disease in humans. Therefore, the search for substances for the treatment of viral diseases can be accomplished through the use of bacteriophages as models for eukaryotic cell viruses.
