Gastric and enteric Helicobacter species have been associated with malignant and inflammatory diseases of the stomach, liver, gall bladder and intestine. Matrix metalloproteinases (MMPs) participate in degradation of extracellular matrix, which allows bacteria to come in contact with and interact with the cells. Enhanced level of MMPs facilitates metastasis and cell invasion of tumor cells by r...

BACKGROUND Poultry represent an important source of foodborne enteropathogens, in particular thermophilic Campylobacter species. Many of these organisms colonize the intestinal tract of broiler chickens as harmless commensals, and therefore, often remain undetected prior to slaughter. The exact reasons for the lack of clinical disease are unknown, but analysis of the gastrointestinal microbiota...

Previous investigations conducted in our laboratory have shown that the arginase system and, consequently, the Krebs ornithine cycle, is reactivated in baby chicks experimentally infected with Salmonella pullorum (Ross et al., 1956). A similar reactivation, as evidenced by an alteration in the nitrogen excretion pattern, was demonstrated in chicks treated with the endotoxin of S. pullorum (Dool...
