Summary: This research investigated antibiotic-induced drug resistance and biofilm formation mechanism in Salmonella enteritidis. Testing revealed high resistance rates to nalidixic acid, ampicillin, and streptomycin, and severe multidrug resistance. Gene expression during biofilm formation showed fsr's impact on ge1E, esp, and ebpA genes. Carrying of drug resistance genes and their relationship to biofilm formation were also explored.

Summary: This study evaluated the antibiotic resistance, antibiotic resistance genes, and biofilm formation capacity of 34 Salmonella enterica serovar Entritidis strains. The genetic diversity of the strains was analyzed using PFGE. The results showed that the strains had high resistance to cefuroxime, nalidixic acid, and ciprofloxacin, and most of them were biofilm producers. Genetic analysis revealed high homogeneity among strains with the same XbaI PFGE profile, indicating the need for multiple typing methods for reliable results.

Summary: The biofilm formation of Salmonella Enteritidis was assessed under sub-minimal inhibitory concentrations of ethanol. Ethanol at subinhibitory concentrations was found to stimulate biofilm formation, decrease swimming motility, and enhance cell auto-aggregation and quorum sensing. However, other cell characteristics were not significantly affected by ethanol.

Summary: The PhoPQ two-component system plays a crucial role in the resistance formation of quinolone and cephalosporin-resistant S. Enteritidis. PhoP regulates genes associated with envelope homeostasis, the osmotic stress response, and the redox balance to confer antibiotic resistance. Additionally, PhoQ senses quinolones and cephalosporins by directly binding to them. These findings provide insights into bacterial antibiotic resistance and suggest PhoPQ as a potential drug target for overcoming S. Enteritidis resistance.

Summary: The surfaces of poultry slaughterhouse equipment are major sources of Pseudomonas contamination, causing spoilage of poultry meat during refrigerated storage. Pseudomonas strains with high biofilm-forming ability were isolated from different surfaces, and their biofilm formation was studied. These strains produced biofilm on polystyrene microplates, and some strains were identified as P. fragi, P. fluorescens, P. lundensis, and P. cedrina. The ability of these strains to form biofilms with S. enteritidis depended on the timing of biofilm formation and the contribution of S. enteritidis.

Summary: This study investigates the effects of antibiotics and sanitizers on biofilm forming Salmonella isolated from seafood contact surfaces. The study found that iodophor and sodium hypochlorite can effectively reduce Salmonella biofilm formation. Additionally, the isolates showed a general resistance to quinolone drugs.

Summary: This study investigated the antimicrobial tolerance of Salmonella isolates from food processing environments, finding different levels of biofilm formation and antibiotic resistance. Some isolates exhibited resistance to sanitizers and antibiotics, potentially due to their strong biofilm forming ability causing them to persist on surfaces.

Summary: This study analyzed a collection of Salmonella enterica strains collected in Italy over a 3-year period. The prevalence of colistin-resistant strains was determined, and mobile colistin resistance (mcr) genes were detected. Additionally, chromosomal mutations potentially involved in colistin resistance were identified. The study highlights the importance of national surveillance in monitoring colistin resistance and studying new mechanisms.

Summary: This study isolated and identified 26 S. Enteritidis isolates from a chicken processing facility using PCR and PFGE, all of which were genetically identical and had potential impacts on human health and economic revenue. Continuous monitoring of the molecular and biofilm characteristics of S. Enteritidis is necessary to enhance food safety.

Summary: This study investigated the association between biofilm formation and antibiotic resistance in extensively drug-resistant Escherichia coli isolates. The results showed that stronger biofilm formation was correlated with larger proportions of extensively drug-resistant isolates. These findings provide novel insights for the prevention and treatment of E. coli-related infections.
