Although induction of T cell responses to fed Ag (oral tolerance) is thought to happen within
the organized lymphoid tissue of the gut, we found that mice lacking Peyer's patches, B cells …

We showed previously that fructooligosaccharides (FOS) decrease the resistance to
salmonella infection in rats. However, the mechanism responsible for this effect is unclear …

The cellular pathways of infection utilized by pathogenic enteric bacteria have important
implications for their clinical manifestations. Yersinia reaches Peyer's patches via M cells …

Intestinal Listeria monocytogenes infection is not efficient in mice and this has been
attributed to a low affinity interaction between the bacterial surface protein InlA and E …

In recent years, the use of in-feed antibiotics for growth and disease prevention in livestock
production has been under severe scrutiny. The use and misuse of in-feed antibiotics has …

Macrophages have long been regarded as the main target encountered by Salmonella
typhimurium, a Gram-negative facultative intracellular pathogen that invades the intestinal …

Probiotic Fresh Cheese (PFC) is a suitable vehicle for the oral administration of
Streptococcus thermophilus, Lactococcus lactis (lactic acid starter bacteria), Bifidobacterium …

Mucosal surfaces lining the lung and the gut are constantly exposed to environmental
antigens, commensal organisms, and pathogens. Consequently, the host's immune system …

Survival and growth of salmonellae within host cells are important aspects of bacterial
virulence. We have developed an assay to identify Salmonella typhimurium genes that are …

The ability of salmonellae to become internalized and to survive and replicate in amoebae
was evaluated by using three separate serovars of Salmonella enterica and five different …
