Summary: In this study, a novel avian pathogenic Escherichia coli phage, vB_EcoS_GN06, was isolated from sewage. The phage demonstrated wide tolerances of pH and temperature, and showed strong lytic ability and inhibition of bacterial growth and biofilm formation. Analysis of the phage's genome assigned it to the genus Tequintavirus and indicated its safety in application. This research suggests that GN06 may serve as a potential candidate for phage therapy.

Summary: In this study, a specific bacteriophage against Salmonella Typhimurium was isolated and characterized. The bacteriophage showed fast replication and high burst size, and it remained stable under a wide range of temperature and pH conditions. Bioinformatics analysis revealed the absence of lysogenic genes and virulence genes in the bacteriophage genome. Furthermore, experiments demonstrated that the bacteriophage effectively reduced the presence of Salmonella Typhimurium in chilled mutton.

Summary: In this study, the efficacy of different bacteriophages against E. coli O157 was evaluated, revealing that the combination of phages did not always follow the individual phage activity. Factors such as temperature, exposure time, and phage strains influenced the interactions among phages, with some combinations showing facilitation while others demonstrated antagonistic effects. The development of phage cocktails should consider confirming lack of antagonism and preferably facilitation or synergistic effects among constituent phages.

Summary: In this study, a polyvalent broad-spectrum phage, GSP044, was isolated from pig farm sewage, which showed the ability to simultaneously lyse multiple serotypes of Salmonella and E. coli. GSP044 has a short latent period, high stability, and good tolerance to chloroform. Genome sequencing analysis revealed that GSP044 belongs to the Demerecviridae family, Epseptimavirus genus, and does not contain any lysogenicity-related, virulence-related, or antibiotic resistance-related genes. The initial application of phage GSP044 showed promising results in reducing biofilm formation, degrading mature biofilm, and decreasing the number of colonized S. Enteritidis in vitro and in vivo.

Summary: In this study, a novel phage vB_PaeP_PS28 with high lytic activity against Pseudomonas aeruginosa was isolated from sewage. The phage showed effective inhibition on the growth of planktonic cells and degradation of biofilms. In a mice infection model, treatment with the isolated phage significantly enhanced the survival rate and reduced the bacterial load in liver and kidney. These findings support the potential application of phage therapy in treating P. aeruginosa infections.

Summary: Urinary tract infections (UTIs) are a common bacterial infection, with Escherichia coli being the main cause. Antibiotic-resistance in UTIs has led to the exploration of alternative therapies, such as bacteriophages. In this study, three novel bacteriophages were isolated and characterized, showing efficient infection and killing of laboratory and multidrug-resistant clinical E. coli strains. These phages also demonstrated the ability to infect intestinal pathogenic E. coli strains. This research suggests that these phages may serve as a potential alternative treatment for antibiotic-resistant E. coli strains causing UTIs and intestinal infections.

Summary: This study aimed to gain a better understanding of the antibiotic prescribing-use-dispensation dynamic in Malta from the perspective of GPs, pharmacists, and parents. The results showed that while there was generally high awareness of antibiotic overuse and ABR among the interviewees, issues such as antibiotic demand, non-compliance, and over-the-counter dispensing still existed. However, the interviewees believed that the public is more accepting of alternative strategies, such as delayed antibiotic prescription. Both GPs and pharmacists were enthusiastic about their roles as patient educators in raising knowledge and awareness in this context. Overall, there is room for improvement in antibiotic use in Malta.

Summary: A systematic study was conducted to understand the bactericidal mechanism of ultrasound assisted Fenton reaction (Sono-Fenton) against multidrug resistant Acinetobacter baumannii. The study found that SF achieved approximately 99% inactivation efficiency against A. baumannii within 90 minutes under weak acidic conditions. The combination of ultrasound and H2O2 was found to be more efficient, and the generation of multiple reactive oxygen species (ROS) may have led to the membrane damage of the bacteria.

Summary: This systematic review synthesizes the evidence on the value of community-based behavior change interventions to improve antibiotic use. The findings show positive emerging evidence of the benefits of such interventions, especially multifaceted ones. Combining education with persuasion may be more effective than solely educational interventions. However, standardized approaches are needed in study design and outcome measurements.

Summary: Phage therapy has shown great potential as an alternative treatment, and this study focused on evaluating the effectiveness of two Staphylococcus phages. The results showed that these phages had high adsorption efficiencies and stability, and demonstrated significant bacterial killing effects both in vitro and in vivo. Additionally, the study found that uninfected bacterial cells exhibited transient phage resistance during phage-bacterial interactions.
