Special Issue Information

Dear Colleagues,

Volume I (https://www.mdpi.com/journal/foods/special_issues/Food_Bioactives) and Volume II (https://www.mdpi.com/journal/foods/special_issues/T5ES6N4630) of this Special Issue were incredibly successful. We would like to express our gratitude to everyone involved for their participation, as well as for the support of numerous high-profile scientists.

Foodborne pathogenic bacteria threaten the safety of the food system from farms to our tables. To enhance the safety of our food system, the first step is to understand how the food system has been and could still be contaminated by pathogenic bacteria, such as pathogenic Escherichia coli, non-typhoidal Salmonella, Vibrio parahaemolyticus, Staphylococcus aureus, Listeria monocytogenes and other emerging and re-emerging pathogenic bacteria. On the other hand, we also need to understand how these bacteria can survive different processing and preservation steps in the food system. As of now, biofilm formation and antimicrobial resistance may explain the mechanisms behind the bacteria’s survival. However, gaps in our knowledge still exist. Once we have acquired basic information, we will be able to prevent and control the contamination of foodborne pathogenic bacteria.

Salmonella enteritidis is a major cause of foodborne illness worldwide, and the emergence of ciprofloxacin-resistant strains poses a significant threat to food safety and public health. This study aimed to investigate the prevalence, spread, and mechanisms of ciprofloxacin resistance in S. enteritidis isolates from food and patient samples in Shanghai, China. A total of 1625 S. enteritidis isolates were screened, and 34 (2.1%) exhibited resistance to ciprofloxacin. Pulsed-field gel electrophoresis (PFGE) results suggested that clonal spread might have persisted among these 34 isolates in the local area for several years. Multiple plasmid-mediated quinolone resistance (PMQR) genes, GyrA mutations in the quinolone resistance-determining region (QRDR), and overexpression of RND efflux pumps were identified as potential contributors to ciprofloxacin resistance. PMQR genes oqxAB, qnrA, qnrB, and aac(6’)-Ib-cr as well as GyrA mutations S83Y, S83R, D87Y, D87G, D87N, and S83Y-D87Y were identified. The co-transfer of the PMQR gene oqxAB with the ESBL gene blaCTX-M-14/55 on an IncHI2 plasmid with a size of ~245 kbp was observed through conjugation, highlighting the role of horizontal gene transfer in the dissemination of antibiotic resistance. Sequencing of the oqxAB-bearing plasmid p12519A revealed a 248,746 bp sequence with a typical IncHI2 backbone. A 53,104 bp multidrug resistance region (MRR) was identified, containing two key antibiotic resistance determinants: IS26-oqxR-oqxAB-IS26 and IS26-ΔISEcp1-blaCTX-M-14-IS903B. The findings of this study indicate that ciprofloxacin-resistant S. Enteritidis poses a significant threat to food safety and public health. The persistence of clonal spread and the horizontal transfer of resistance genes highlight the need for enhanced surveillance and control measures to prevent the further spread of antibiotic resistance.

Two-component systems (TCS) of Salmonella enterica serovar Enteritidis are composed of a histidine kinase and a response regulator (RR) and represent a critical mechanism by which bacteria develop resistance to environmental stress. Here, we characterized the functions of RRs in TCS in the formation of stress tolerance, motility and biofilm using twenty-six S. Enteritidis RR-encoding gene deletion mutants. The viability results unraveled their essential roles in resistance to elevated temperature (GlrR), pH alterations (GlrR, TctD, YedW, ArcA and YehT), high salt (PhoB, BaeR, CpxR, PhoP, UvrY and TctD), oxidative stress (PhoB, YedW, BaeR, ArcA, PhoP, UvrY, PgtA and QseB) and motility (ArcA, GlnG, PgtA, PhoB, UhpA, OmpR, UvrY and QseB) of S. Enteritidis. The results of the crystal violet staining, microscopy observation and Congo red binding assays demonstrated that the absence of ArcA, GlnG, PhoP, OmpR, ZraR or SsrB in S. Enteritidis led to a reduction in biofilms and an impairment in red/dry/rough macrocolony formation, whereas the absence of UvrY exhibited an increase in biofilms and formed a brown/smooth/sticky macrocolony. The results indicated the regulatory effects of these RRs on the production of biofilm matrix, curli fimbriae and cellulose. Our findings yielded insights into the role of TCSs, making them a promising target for combating S. Enteritidis. Full article
