Summary: Phage therapy is a hopeful approach to combat multidrug-resistant bacteria. However, it requires the isolation of new phages or the search for suitable phages in existing libraries. This study proposes a simple PCR method to differentiate between two families of Staphylococcus phages and eleven genera of Klebsiella phages, allowing for rapid screening and identification.

Summary: This study introduces three novel S. aureus jumbo phages: MarsHill, Madawaska, and Machias, isolated from swine production environments in the US. These phages belong to a new clade of S. aureus myophages with similar genome size and protein-coding genes, sharing characteristics with known jumbo phages of Bacillus sp. The phages possess genes encoding complete virion and nonvirion RNA polymerases, homing endonucleases, and a retron-like reverse transcriptase, with presumed uracil-substituted DNA hindering DNA sequencing. These phages also have the ability to transduce host plasmids and infect human S. aureus isolates, highlighting their potential impact on genetic diversity and horizontal gene transfer.

Summary: Subinhibitory concentrations of protein synthesis inhibitor (PSI) antibiotics showed synergy when combined with phages in treating Staphylococcus aureus infections, sensitizing phage-resistant strains and promoting phage infection in vitro and in vivo. This suggests the potential use of phage-PSI antibiotic combination therapies for difficult-to-treat infections caused by phage-resistant S. aureus and MRSA strains.

Summary: This study evaluated the activity of two engineered enzybiotics against a dual biofilm formed by Staphylococcus aureus and Enterococcus faecalis. The cocktail of proteins showed an additive effect in rapidly disrupting the preformed dual biofilm, resulting in over 90% dispersion within 3 hours of treatment. Furthermore, it effectively reduced bacterial cells embedded in the biofilm matrix by over 90% within the same time frame. This is the first successful use of an engineered enzybiotic cocktail to impede the structural integrity of a dual biofilm.

Summary: A gelatin-syringic acid/ZnO nanocomposite with antioxidant, anti-inflammatory, and anticancer activities was synthesized and characterized. The nanocomposite exhibited sustained drug release, high antioxidant ability, dose-dependent inhibition of protein denaturation, and non-toxicity in zebrafish. It also inhibited Hep G2 cell viability and increased oxidative stress caused by mitochondrial damage, leading to cell death. Overall, this study suggests that the gelatin-syringic acid/ZnO nanocomposite has potential for the treatment of hepatocellular carcinoma.

Summary: Grain cultivation and its impacts on the environment, specifically the generation of solid waste and the use of agrochemicals, have attracted much attention. This study proposes a novel approach to achieve self-sustainability in rice farming by reusing green silica waste as an adsorbent for treating pesticide-contaminated effluents. The carbonaceous material obtained from burning rice husks and subsequent treatment exhibited promising adsorption properties towards 2,4-dichlorophenoxyacetic acid (2,4-D) pesticide. The findings suggest that this material has the potential to contribute to the sustainable development of rice farming.
