Previously we found that E. coli O157:H7 inoculated into ligated pig intestine formed attaching and effacing (AE) lesions in some pigs but not in others. The present study evaluated changes in the microbial community and in virulence gene expression

BACKGROUND: Escherichia coli O157:H7 strain 86-24 grown in MacConkey broth (MB) shows almost no adherence to cultured epithelial cells but adheres well in pig ligated intestines. This study investigated the mechanisms associated with the difference b

Components of bacteria have been shown to induce innate antiviral immunity via Toll-like receptors (TLRs). We have recently shown that FimH, the adhesin portion of type 1 fimbria, can induce the innate immune system via TLR4. Here we report that FimH

Verocytotoxin-producing E. coli (VTEC) of serotype O157:H7 have been shown to be important agents of foodborne disease in humans worldwide. While the majority of research effort has been targeted on this serotype it is becoming more evident that othe

Escherichia coli O157 : H7 cells that interact with intestinal epithelial cells in animals and humans do so after passage through the low pH of the stomach. This study compared adherence and its associated virulence gene expression in acid-treated (A

Persistence of bovine Staphylococcus aureus mastitis may be associated with the small colony variant (SCV) form that is adapted to intracellular life and resists elimination by the immune system. This study evaluated antibody-mediated (AMIR) and cell

Persistent bovine Staphylococcus aureus mastitis is attributable to the versatility of this pathogen within the mammary gland environment and to the formation of small colony variants (SCVs) that can survive within host cells. Previous studies had sh

The objective of this study was to determine the efficacy of selected phages individually and in combination in prevention and treatment of diarrhea due to experimental O149:H10:F4 enterotoxigenic Escherichia coli (ETEC) in weaned pigs. For prophylax

The successful use of virulent (lytic) bacteriophages (phages) in preventing and treating neonatal enterotoxigenicEscherichia coliinfections in calves, lambs and pigs has prompted investigation of other applications of phage therapy in food animals.
