Summary: Fresh vegetables are a potential important transmission route for ESBL-producing Enterobacteriaceae, with a contamination rate of up to 82.9%. A total of 15 ESBL-producing isolates were obtained, including 5 multi-drug resistant Serratia fonticola, which can be an environmental reservoir of antibiotic-resistance genes.

Summary: This study determines the prevalence of extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-E) in feces of household and shelter pets in Guadeloupe. The study finds that the only risk factor associated with a higher prevalence of ESBL-E rectal carriage is a stay in a shelter. The study also identifies ESBL-E as mainly Escherichia coli, with certain plasmids carrying antimicrobial resistance genes.

Summary: This study investigated the occurrence of Escherichia coli and antibiotic-resistant E. coli in the Dutch-German transboundary catchment of the Vecht River. The study found a higher proportion of ESBL-EC in German wastewater treatment plants compared to Dutch plants. The modeling approach predicted E. coli concentrations to be below the threshold for good bathing water quality.

Summary: Surface water is a favorable environment for the accumulation and spread of antibiotic resistant bacteria, including ESBL-producing Enterobacteriaceae. The prevalence of ESBL-producing Enterobacteriaceae, particularly E. coli and K. pneumoniae, in aquatic environments worldwide poses a growing threat to public health. This review aims to explore the contamination of ESBL-producing Enterobacteriaceae in freshwater environments and understand their sources and transmission routes, as well as the factors driving their presence.

Summary: Cephalosporin therapy failure is a serious problem worldwide for infection control. Cephalosporin-resistant infections are often caused by multidrug-resistant E. coli producing ESBLs and/or pAmpC beta-lactamases. Analysis of MDR E. coli isolates from a UK hospital revealed a high prevalence of ESBL/pAmpC genetic determinants and significant correlations between resistance genes and specific antibiotics. The findings emphasize the importance of improved antibiotic therapy guidelines, including reduced usage and enhanced surveillance.

Summary: A cross-sectional study was conducted in dairy cattle farms and poultry farms in northern Egypt to assess the prevalence of ESBL-producing Enterobacteriaceae in humans, cattle, and poultry. The study found that the prevalence of ESBL-producing Enterobacteriaceae was 30.0%, 20.0%, and 25.0% in humans, cattle, and poultry, respectively. The majority of the ESBL-producing Enterobacteriaceae showed a multi-drug resistant phenotype.

Summary: The study found ESBL-producing E. coli and K. pneumoniae in raw vegetables, showing high resistance to beta-lactam antibiotics but good sensitivity to beta-lactam/carbapenem antibiotics. The genes carried by these bacteria may be associated with food chains and humans, suggesting that raw vegetables could serve as an important route for the transmission of ESBL-resistant bacteria to humans.

Summary: In recent years, the use and overuse of broad-spectrum antimicrobial agents have led to a growing drug resistance among bacteria. This study aimed to analyze the changes in drug resistance of Gram-negative Enterobacterales over five years. The evaluation of these data will help determine changes in susceptibility to antibiotics used in the hospital and propose new therapeutic options for severe infections. The analysis revealed that the number of multi-resistant K. pneumoniae strains has been increasing, possibly due to the widespread use of broad-spectrum antibiotics during the pandemic.

Summary: Novel approaches to combat antimicrobial resistance (AMR) are needed, and antimicrobial peptides, particularly bacteriocins, have gained attention as potential alternatives to antibiotics. Bacteriocins produced by Staphylococcus, known as staphylococcins, have shown significant antimicrobial potential and are considered promising candidates to combat AMR. Additionally, various bacteriocin-producing Staphylococcus strains, including coagulase-negative staphylococci (CoNS), have been identified as alternative options.

Summary: This study characterized a collection of 20 C. perfringens isolates from poultry affected by necrotic enteritis (NE) at the genomic level, focusing on resistance mechanisms and bacteriocin production. Antimicrobial resistance genes, especially tet genes associated with tetracycline resistance, were found to be prevalent. Interestingly, two isolates carried the erm(T) gene associated with erythromycin resistance, which is rarely reported in other Gram-positive bacteria. The study also revealed a high variability of sequence types and identified unique characteristics in one isolate (C. perfringens MLG7307) that made it impossible to toxinotype.

Summary: This study aimed to reduce the production time of PDO Pecorino Siciliano cheese by comparing two cooking methods and assessing their impact on microbiological composition and lactic acid bacteria populations. The results showed that the different cooking methods did not affect the physicochemical characteristics of the cheese, and sensory evaluation confirmed that the modified production protocol did not significantly alter the product characteristics and overall acceptance. Therefore, cooking under hot water proved to be an effective way to reduce the transformation duration while maintaining the typicality of PDO Pecorino Siciliano cheese.

Results show that OH with higher voltage effectively inactivates microorganisms, slows down lipid oxidation, and maintains sensory quality and amino acids content of milk. The microbial community in milk treated with OH remains relatively stable during storage.

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.

The EU regulation sets qualitative or quantitative food safety criteria for L. monocytogenes and recommends the use of EN ISO 11290-1 as the reference detection method. Our study compares alternative certified methods for detecting L. monocytogenes, highlighting the importance of diversifying available detection methods.

Summary: The effect of multiple sublethal doses of non-thermal plasma treatments on phenotypical changes and the reduction in phytopathogenicity of three species of fungi was investigated. The plasma damaged the surface of the fungal hyphae, decreased their dry biomass, and affected the activity of pectinase and xylanase. Furthermore, the plasma treatments increased the germination rate of artificially infected cucumber seeds and resulted in plants with higher biomass and longer roots and stems. However, the reduction in phytopathogenicity was not complete after the multiple plasma treatments.
