Summary: Antimicrobial resistance bacteria, including Escherichia coli, are widespread and pose a global health and economic burden. Monitoring fecal microbiota is important as it can serve as a potential source of resistant E. coli due to gene transfer between different bacteria. An analysis of 150 E. coli isolates from environmental, animal, and human samples in rural areas of Panama revealed high resistance to tetracycline and the presence of plasmid-associated tetA and tetB genes, suggesting the horizontal transfer of resistance genes within the community.

Summary: Improving the rate of photo-fermentative hydrogen production has been a major challenge in the field of biological hydrogen production using photosynthetic bacteria (PSB) in recent years. In a previous study, it was observed that the expression of tetA gene in R. sphaeroides HY01 under tetracycline (Tc) led to significant enhancement of hydrogen production. Further investigation revealed that Tc-resistant strains consistently showed stable promotion of hydrogen production rate (Rm), with approximately 30% promotion with Tc addition. This study explores the Tc dose-dependent hydrogen promotion of resistant strains and investigates the gene expression differences induced by TetA expression and Tc addition in Rodobacter sphaeroides.

Summary: A simple, low-cost label-free photoelectrochemical biosensing platform based on red blood cell shaped BiVO4 modified g-C3N4 was designed and demonstrated for tetracycline detection. The prepared g-C3N4/BiVO4 heterojunction showed high surface area, excellent stability, and favorable PEC activity. It also served as a nanostructure support for aptamers to construct a visible-light-driven PEC aptasensor. The proposed PEC aptasensor exhibited a favorable linear response to tetracycline and met the detection requirements of food standards. Practical food sample analysis confirmed the accuracy and feasibility of the g-C3N4/BiVO4 heterostructure based PEC platform. This label-free and cost-effective PEC strategy holds great promise for tetracycline determination in food quality control and supervision.

Summary: In this study, two bacteriophages, PECP14 and PECP20, infecting Escherichia coli O157:H7 were isolated and found to be stable under different environmental conditions. These phages exhibited specificity in targeting different host receptors and demonstrated the ability to infect other foodborne pathogens. The efficacy of phage treatment was demonstrated through rapid adsorption and bacterial lysis. Furthermore, purified endolysins derived from these phages showed remarkable bacteriolytic activity not only against E. coli O157:H7 but also against other pathogens. These findings suggest that these phages and their endolysins can be used for biological control of E. coli O157:H7 in various stages of agricultural product production.
