Members of Salmonella enterica are frequently involved in egg and egg product related human food poisoning outbreaks worldwide. In Australia, Salmonella Typhimurium is frequently involved in egg and egg product related foodborne illness and Salmonella Mbandaka has also been found to be a contaminant of the layer farm environment. The ability possessed by Salmonella Enteritidis to colonize repro...

background and objectives: glycoprotein 96 is the primary chaperone of the endoplasmic reticulum. immunization with it induced potent cytotoxic t lymphocyte responses to intracellular bacteria. s. typhimurium is a facultative intracellular bacterium and acquired resistance against this bacterium mainly depends on activity of cytotoxic t cells. this study aimed to evaluate the capacity of glycop...

A multiplex polymerase chain reaction (PCR) assay was developed for the identification of Salmonella enterica serovar Typhimurium. Three sets of primers were designed for detecting O4, H:i, and H:1,2 antigen genes from the antigen-specific genes rfbJ, fliC, and fljB, respectively. These were evaluated in a multiplex PCR assay by using DNAs from S. enterica serovar Typhimurium, 15 other Salmonel...

Mice defective in the ability to produce the tumor necrosis factor alpha p55 receptor (TNFalphap55R) were orally challenged with a number of Salmonella typhimurium HWSH derivatives that differ in virulence. In comparison to TNFalphap55R+/+ mice, TNFalphap55R-/- mice succumbed earlier to challenge with wild-type S. typhimurium HWSH and S. typhimurium HWSH purE. In contrast, TNFalphap55R-/- mice ...

The Salmonella enterica serovar Typhimurium strain UK-1 exhibits the highest invasion and virulence attributes among the most frequently studied strains. S. Typhimurium UK-1 has been used as the foundation for developing recombinant vaccines and has been used extensively on virulence and colonization studies in chickens and mice. We describe here the complete genome sequence of S. Typhimurium U...

BACKGROUND Salmonella enterica serovar Choleraesuis (S. Choleraesuis) infection causes a systemic disease in pigs. Vaccination could represent a solution to reduce prevalence in farms. In this study, we aimed to assess the efficacy of an attenuated strain of Salmonella enterica serovar Typhimurium (S. Typhimurium ΔznuABC) against S. Choleraesuis infection. The vaccination protocol combined prim...

BACKGROUND AND AIMS Both deoxynivalenol (DON) and nontyphoidal salmonellosis are emerging threats with possible hazardous effects on both human and animal health. The objective of this study was to examine whether DON at low but relevant concentrations interacts with the intestinal inflammation induced by Salmonella Typhimurium. METHODOLOGY By using a porcine intestinal ileal loop model, we i...

Salmonella Enteriditis and Salmonella Typhimurium are commonly isolated during egg-related outbreaks of salmonellosis and represent a significant international public health issue. In Australia, Salmonella Typhimurium is the most common serovar identified in egg product related foodborne outbreaks. While a number of studies have investigated Salmonella shedding and host responses to infection, ...

salmonella enterica is considered as one of the major pathogens in public health, worldwide. diseases caused by salmonella enterica serovars are especially prevalent in developing countries. it is one of the emerging pathogen in food-borne diseases, which is often found in contaminated chicken eggs. the aim of this study was to apply a pcr–rflp method using sau3ai and hhai restriction endonucle...
