Since the early 1970’s a number of large Salmonella outbreaks have been associated with low aw food products, including chocolate, cereal, peanut butter, spices, and powdered infant formula. This research is design to help the food industry to determine Salmonella survival in the production environment and thus understand the potential risk of cross contamination to the product. The studies sou...

The microRNAs (miRNAs) have been shown to play important roles in the development of the immune system and in regulation of host inflammation responses. Probiotics can effectively alleviate the inflammation caused by Salmonella in chickens. However, whether and how miRNAs are involved in modulation of the inflammation response in the gut of chickens have not been reported. In this study, the im...

Lactobacillus pentosus (L. pentosus) strain S-PT84, isolated from Kyoto pickles, enhances splenic natural killer (NK) cell activity, and has high T-helper1 (Th1) cytokine and type 1-IFN (IFN-α) inducing activity. In the present study, we investigated the influence of S-PT84 ingestion on the mucosal immunity of healthy and Salmonella Typhimurium (S. Typhimurium)-infected mice. In the S. Typhimur...

In this report we briefly describe an immunoglobulin G3 monoclonal antibody, 2G6/1H11, which binds purified lipid A from Salmonella minnesota and a lipid A precursor molecule derived from Salmonella typhimurium. 2G6/1H11 does not bind well to purified whole S. typhimurium lipopolysaccharide (LPS), S. minnesota LPS, LPS preparations from a series of S. minnesota rough mutants, or intact S. typhi...

The D-values of Listeria monocytogenes and Salmonella Typhimurium at various surface pasteurization temperatures were determined for low-fat turkey bologna. Four cm2 meat squares were sterilized by irradiation prior to inoculation with 0.1 mL of a 10(8) cfu/mL culture, aseptically packaged in a linear low-density polyethylene pouch, and vacuum-sealed. Thermal treatments were administered by sub...

This review documents the sporadic reporting of poultry Salmonella serovars in South Africa, Egypt, Indonesia, India, and Romania, five countries selected based on the importance of their distribution in different regions of the world and their cumulative significant population size of 1.6 billion. South Africa reported contamination of its poultry carcasses by S. Hadar, S. Blockley, S. Irumu, ...

OBJECTIVE With the growing interests of bacteria as a targeting vector for cancer treatment, diverse genetically engineered Salmonella has been reported to be capable of targeting primary or metastatic tumor regions after intravenous injection into mouse tumor models. The purpose of this study was to investigate the capability of the genetically engineered Salmonella typhimurium (S. typhimurium...

Surveillance of Salmonella enterica subsp. enterica serovar Typhimurium (S. Typhimurium) is generally considered to benefit from molecular techniques like multiple-locus variable-number of tandem repeats analysis (MLVA), which allow earlier detection and confinement of outbreaks. Here, a surveillance study, including phage typing, antimicrobial susceptibility testing and the in Europe most comm...

AIMS This study aimed to determine the effect of a cell-free supernatant of Lactobacillus paracasei ATCC 27092 with and without rice bran extract (RBE) on Salmonella Typhimurium 14028s growth, and to identify a metabolite profile with antimicrobial functions. METHODS AND RESULTS Supernatant was collected from overnight cultures of L. paracasei incubated in the presence (LP+RBE) or absence (LP...

Salmonella typhimurium LT-2 was compared with radioresistant (B/r) and radiosensitive (B(s-2)) strains of Escherichia coli in respect to the survival, deoxyribonucleic acid (DNA) breakdown, and DNA synthesis after X irradiation. It is shown that S. typhimurium LT-2 is about four times more sensitive than E. coli B/r but less sensitive than B(s-2). The DNA breakdown is in S. typhimurium LT-2 low...
