Intestinal epithelial cells provide an important colonization niche for Salmonella enterica serovar Typhimurium during gastrointestinal infections. In infected epithelial cells, a subpopulation of S Typhimurium bacteria damage their internalization vacuole, leading to escape from the Salmonella-containing vacuole (SCV) and extensive proliferation in the cytosol. Little is known about the bacter...

background: salmonella enterica serovar typhimurium is one of the most important serovars of salmonella enterica and is associated with human salmonellosis worldwide. many epidemiological studies have focused on the characteristics of salmonella typhimurium in many countries as well as in asia. this study was conducted to investigate the genetic characteristics of salmonella typhimurium using m...

Infection of mice with Salmonella typhimurium results in systemic infection and a disease similar to that seen in humans after infection with S. typhi. The innate immune system can restrict replication of S. typhimurium to a certain degree, but for effective control and eradication of bacteria, acquired immunity is essential. Salmonella infection induces the generation of specific CD4+ and CD8+...

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...

background :    due to excessive consumption of synthetic drugs, drug resistance rate of pathogenic bacteria is increasing and there is an ever-increasing need to find new safe compounds to tackle this problem. this study was conducted to investigate the consequences of chavill extract on the growth and viability of gastrointestinal pathogenic bacterium and probiotics bacteria.   methods :    t...

Carboxymethylated cashew gum (CMCG) film was electrodeposited on a gold surface for immobilization of polyclonal anti-Salmonella antibodies. The immunosensor response obtained by chronoamperometry in milk contaminated with Salmonella enterica serovar Typhimurium. CMCG suitable platform the assembly and showed stable structure 12% coefficient variation after 30 sweeps phosphate saline buffer (pH...

background escherichia coli o157:h7, vibrio cholerae, and salmonella typhimurium are pathogenic bacteria found in contaminated water and food. no assay method is currently available on simultaneous detection or identification of all the three pathogens. our aim was to develop a rapid and reliable method for this purpose. materials and methods a protocol for sample collection, and a pcr procedur...

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, ...

Systemic administration of Salmonella enterica serovar Typhimurium to tumour bearing mice results in preferential colonization of the tumours and retardation of tumour growth. Although the bacteria are able to invade the tumour cells in vitro, in tumours they were never detected intracellularly. Ultrastructural analysis of Salmonella-colonized tumours revealed that the bacteria had formed biofi...

Salmonella enterica serovar typhimurium a hyperreplicating population, exists inside the cytoplasm of infected epithelial cells. This population expresses genes belonging to the Salmonella Pathogenicity Island 1 (SPI-1) after exiting from the Salmonella Containing Vacuole (SCV) (Knodler, et al., 2010) (Beuzon, et al., 2002). SCV provides a protective niche to Salmonella typhimurium and the reas...
