Background Efflux pumps belonging to the resistance-nodulation-division (RND) superfamily in bacteria are involved in antibiotic resistance and solvent tolerance but have an unknown physiological role. EmhABC, a RND-type efflux pump in Pseudomonas fluorescens strain cLP6a, extrudes hydrophobic...
The safety of low water activity (aW) foods is a concern due to the survival of low-infectious dose pathogens such as Escherichia coli and Salmonella. Desiccation of non-heat resistant E. coli and Salmonella increases their heat resistance; therefore, a non-thermal alternative is necessary to...
High Intensity Pulsed Light Emitting Diode (LED) Treatment for Simultaneous Salmonella Inactivation and Drying of Wheat Flour and Pet FoodDownload
According to the world health organization, almost 600 million people, or 1 in 10 people suffer from foodborne illnesses globally. Food industry uses several intervention methods to produce safe food products however, cases of food recalls and outbreaks due to microbial pathogens keep increasing...
Influence of Water Activity on Thermal Resistance of Salmonella enterica and Quality changes in Low-moisture FoodsDownload
Low-moisture foods (with aw < 0.85) including pet foods and black pepper powder have been associated with major recalls due to contamination by Salmonella spp. Increased thermal resistance and prolonged survival at low-moisture conditions are major challenges to achieve effective inactivation of...
A number of recent outbreaks related to pathogens in low-moisture foods have created urgency for studies to understand the possible causes and identify potential treatments to improve low-moisture food safety. Thermal processing holds the potential to eliminate pathogens such as Salmonella in...
One potential role of miRNAs is to buffer variation in gene expression, although conflicting results have been reported. To investigate the buffering role of miRNAs in response to Salmonella infection in pigs, we sequenced miRNA and mRNA in whole blood from 15 pig samples before and after...
Microbiological quality of organic vegetables produced in soil treated with different types of manure and mineral fertilizerDownload
An attempt was made to evaluate microbiological quality of horticultural crops grown organically. Three species of vegetables were used, lettuce (Lactuva sativa), radish (Raphanus sativus) and spinach (Tetragonia expansa), grown organically, in fertile soil. Six different treatments were applied:...
The intestinal microbiota has been found to play a central role in the colonization of Salmonella enterica serovar Typhimurium in the gastrointestinal tract. In this study, we present a novel process through which Salmonella benefit from inflammatory induced changes in the microbiota in order to...
Prevalence of Salmonella in beef cattle lymph nodes and the role of iron uptake proteins in Salmonella growth and survival in food productsDownload
Salmonella enterica subspecies Enteritidis and Typhimurium are the cause of most cases foodborne salmonellosis. Salmonella is predominately found in poultry, beef and dairy products. It is an intracellular pathogen, known to enter the lymphatic system and it has been found in the lymph nodes of...
Specific detection of Campylobacter jejuni using the bacteriophage NCTC 12673 receptor binding protein as a probeDownload
Campylobacter jejuni is found in the intestines of poultry, cattle, swine, wild birds and pet animals and is the major cause of foodborne gastroenteritis in developed countries. We report the use of the receptor binding protein (RBP) of Campylobacter bacteriophage NCTC 12673 for the specific...
