Summary: The objective of this study was to assess the prevalence and types of extended-spectrum β-lactamase (ESBL)-producing bacteria in retail seafood. A literature review found that the median prevalence of ESBL-contaminated products globally was 19.4%, with significantly higher rates in Asia compared to Europe and Africa. Among the analyzed isolates, 44.8% were ESBL-positive, with CTX-M being the predominant type (93.6%).

Summary: The study aimed to diagnose Salmonella from chickens and calves, determine its resistance to antimicrobials, characterize integrons and beta lactamase genes in MDR Salmonella, and detect genetic relationships between isolates using ERIC PCR. Results showed MDR in Salmonella isolates and the presence of blaTEM and class 1 integron genes. ERIC PCR revealed clonal relationships between isolates, with S. Enteritidis isolates from poultry and calves showing 100% similarity, indicating possible cross-infection between animals on the same farm, while S. Kentucky isolates showed lower serovarities.

Summary: This study found that resistance to colistin was very low in pigs in 2008-2009, associated with the mcr-1 gene, and undetected in 2018; resistance to 3rd generation cephalosporins increased in 2018, mainly associated with ESBL producers. Most serotypes of Salmonella involved in antimicrobial resistance displayed a multidrug resistance pattern.

Summary: This study investigated the occurrence of antimicrobial resistance among Salmonella strains isolated from food products. Multiple serovars of Salmonella with resistance to commonly used antibiotics were identified. Genomic analysis revealed the presence of antibiotic resistance genes within integrons in plasmids or chromosomal islands. Pathogenicity islands were also found in the genomes of the sequenced strains. The emergence of multidrug-resistant Salmonella strains highlights the need for further research on transmission pathways and monitoring of these microorganisms' distribution.

Summary: Penems have shown potential as antibacterials and beta-lactamase inhibitors, but their clinical use is limited compared to carbapenems. Faropenem, with a C-2 tetrahydrofuran ring, is resistant to some beta-lactamases. Studies on reactions of faropenem with beta-lactamases demonstrate different outcomes, suggesting further research is needed for optimizing the interactions between penems and beta-lactamases.

Summary: This study compared the efficacy of flomoxef with other beta-lactam antibiotics against extended-spectrum beta-lactamases (ESBL)-producing bacteria of clinical relevance. The results demonstrated that flomoxef showed good bactericidal effects and effectively inhibited the growth of ESBL-producing strains, even those with a high minimum inhibitory concentration (MIC) value. Therefore, flomoxef may be a promising alternative in the context of carbapenems sparing stewardship.

Summary: Six tet(X4)-positive Klebsiella pneumoniae strains were isolated from pork samples in China, one of which was hypermucoviscous and hypervirulent. The tet(X4) gene was located on a plasmid with a similar structure to blaKPC-2-positive plasmids in hvKp, and it could be transferred to E. coli and ST11 hvKp without a significant fitness cost and persist stably. This is the first report of tet(X4)-positive hvKp in animals, highlighting the urgent need for global surveillance in clinical and animal farming settings.

Summary: This study investigated the prevalence of qnrVC genes in foodborne Vibrio strains collected in Shenzhen, China, from August 2015 to April 2017. The presence of qnrVC genes was shown to enhance ciprofloxacin resistance in Vibrio strains. Mutations in the gyrA and parC genes were commonly associated with ciprofloxacin resistance. The study also found 14 variant genes containing novel mutations, with 85.7% being qnrVC5-like alleles.

Summary: Although not approved for animal use, carbapenems have been increasingly detected in farm animals. This study investigated NPB recovered from chicken feces and environmental samples in three broiler farms. The results showed a high prevalence of NPB carrying the blaNDM gene, indicating persistent contamination and transmission within the farm system. Strict control measures are required to prevent the spread of animal-borne NPB to the environment and community.

Summary: The role of Proteus mirabilis in food safety was previously unknown. Three P. mirabilis strains (swupm1, swupm2, and swupm3) isolated from fresh-cut fruits differed in swarming motility, with swupm1 and swupm2 exhibiting the characteristic bull's-eye phenotype. These strains grew faster and produced stronger biofilm than swupm3. Additionally, they were multidrug-resistant and highly virulent in Galleria mellonella, with swupm1 being the most virulent. P. mirabilis was found to survive in fresh-cut cantaloupe at 4 degrees C and accelerate the decay of fresh-cut fruits at 25 degrees C. The volatile components of fresh-cut cantaloupe were dramatically changed by P. mirabilis strain swupm1.

Summary: This study investigated the prevalence and characteristics of OXA-232 type carbapenemase in Zhejiang Province, China from 2018 to 2021. The results showed that OXA-232 is the most prevalent OXA-48-like derivative, and ST15 K. pneumoniae isolates are the major carriers. The transmission of ColKP3-type plasmid to E. coli highlighted the importance of understanding the transmission mechanism to prevent the spread of OXA-232 to other species.

Summary: Klebsiella pneumoniae has become a major bacterial pathogen in hospitals, with a high mortality rate. Factors contributing to its virulence are the overproduction of capsular polysaccharide (CPS) and the hypermucoviscosity (HMV) phenotype. This study investigated the functional characteristics of plasmid-borne rmp homologues in clinical hypervirulent K. pneumoniae strains. The results showed that the rmp homologues play a key role in regulating the HMV phenotype and CPS production in K. pneumoniae.

Summary: A new quinolone resistance gene, qnrS, was found in foodborne Vibrio spp., which could mediate resistance to ciprofloxacin and cephalosporins. The qnrS2 gene could be found on both the chromosome and plasmids, with the pAQU-type qnrS2-bearing conjugative plasmids able to mediate resistance to both ciprofloxacin and cephalosporins. Transmission of this plasmid among Vibrio spp. may lead to the emergence of multidrug-resistant pathogens.

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.

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.
