Salmonellosis caused by Salmonella Typhimurium is one of the most important bacterial zoonotic diseases. The bacterium persists in pigs resulting in asymptomatic 'carrier pigs', generating a major source for Salmonella contamination of pork. Until now, very little is known concerning the mechanisms used by Salmonella Typhimurium during persistence in pigs. Using in vivo expression technology (I...
Salmonella enterica serovar Typhimurium and S.enterica serovar Enteritidis are the most frequently isolated serovars from food-borne diseases throughout the world. According to their antigenic profiles, salmonella shows different disease syndromes and host specificities. It is necessary and important to discriminate salmonella serovars from each other in order to ensure that each pathogen and i...
A series of bacteriophages, lytic for bacteria belonging to the genera Escherichia and Salmonella, were isolated. The phages were isolated from fecal samples, intestinal contents of turkey poults, and carrier cultures of S. typhimurium, S. typhimurium var copenhagen, S. heidelberg, and E. coli. The feasibility of using different habitats as sources of Salmonella phages was evaluated. The carrie...
Efficient invasion of non-phagocytic cells, such as intestinal epithelial cells, by Salmonella Typhimurium is dependent on the Salmonella Pathogenicity Island 1 (SPI-1)-encoded Type Three Secretion System. The environmental cues involved in SPI-1 induction are not well understood. In vitro, various conditions are used to induce SPI-1 and the invasive phenotype. Although lysogeny broth (LB) is w...
Salmonella enterica is a significant cause of gastroenteritis worldwide, with serovars Typhimurium and Heidelberg being particularly prevalent, which have broad host ranges infecting poultry, dairy animals, and humans. Traditional methods used for the detection of Salmonella from contaminated food products are time-consuming and labor-intensive. The aim of this study was to develop a sensitive ...
OBJECTIVE In Australia, Salmonella serovar Typhimurium (S. Typhimurium) is the predominant zoonotic serovar in humans and is frequently isolated from layer hens. Vaccination against this serovar has been previously shown to be effective in broilers and the aim of this current study was to assess and determine the best vaccination strategy (live or inactivated) to minimise caecal colonisation by...
The speG gene has been reported to regulate polyamine metabolism in Escherichia coli and Shigella, but its role in Salmonella remains unknown. Our preliminary studies have revealed that speG widely affects the transcriptomes of infected in vitro M and Caco-2 cells and that it is required for the intracellular replication of Salmonella enterica serovar Typhimurium (S. Typhimurium) in HeLa cells....
objective: teucrium polium l. (family lamiaceae) is a wild-growing flowering plant, found abundantly in south-western asia, europe and north africa. traditionally, t. polium has been used for different pathological conditions such as gastrointestinal disorders, inflammations, diabetes and rheumatism. the purpose of this study was to evaluate the antimicrobial effect of ethanol extract of teucri...
We report the first complete genomic sequence of Salmonella enterica subsp. enterica serovar Typhimurium strain ATCC 13311, the leading food-borne pathogen and a reference strain used in drug resistance studies. De novo assembly with PacBio sequencing completed its chromosome and one plasmid. They will accelerate the investigation into multidrug resistance in Salmonella Typhimurium.
Salmonella enterica serovar Typhimurium is an important intestinal pathogen in swine. This study was performed to document the early cellular invasion of Salmonella serovar Typhimurium in swine ileum. Ileal gut-loops were surgically prepared in ten 4- to 5-week-old mixed-breed pigs and inoculated for 0-60 minutes. Loops were harvested and prepared for both scanning and transmission electron mic...
