An in vivo proteomic study of the interaction between Salmonella Typhimurium and porcine ileum mucosa.
The enteropathogen Salmonella Typhimurium is one of the main causes of porcine and human enterocolitis. We have used a 2-DE, MALDI-TOF/TOF-based approach to characterize in vivo proteome changes in porcine ileum mucosa after pathogen interaction. Ileum samples from non-infected and orally infected animals were collected at 2 days post infection and S. Typhimurium presence was confirmed by immun...
متن کاملEarly epithelial invasion by Salmonella enterica serovar Typhimurium DT104 in the swine ileum.
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...
متن کاملSalmonella Typhimurium interferes with the humoral immune response in pigs
Foodborne salmonellosis is one of the most important bacterial zoonotic diseases worldwide. Salmonella Typhimurium is the serovar most frequently isolated from slaughter pigs in Europe. Circumvention of the host’s immune system by Salmonella might contribute to persistent infection of pigs. We found that Salmonella Typhimurium strain 112910a, which is able to persist in pigs, was capable of dow...
متن کاملImmunogenic potential of a Salmonella Typhimurium live vaccine for pigs against monophasic Salmonella Typhimurium DT 193
BACKGROUND Monophasic Salmonella Typhimurium (mSTM) strains account for up to 8.6% of all human Salmonellosis cases. They have an increasing prevalence during recent years and several human cases with hospitalisation were reported. These strains are often isolated from pigs and pork - one primary source of human infection. A Salmonella Typhimurium (STM) live vaccine has been proven successful i...
متن کاملHtpG contributes to Salmonella Typhimurium intestinal persistence in pigs
Salmonella enterica subspecies enterica serovar Typhimurium (Salmonella Typhimurium) contamination of pork, is one of the major sources of human salmonellosis. The bacterium is able to persist and hide in asymptomatic carrier animals, generating a reservoir for Salmonella transmission to other animals and humans. Mechanisms involved in Salmonella persistence in pigs remain poorly understood. In...
