Quorum sensing, the monitoring of population density by bacteria, is used to coordinately control gene expression and therefore particular behaviors under conditions of high cell density. Such group behaviors provide advantages to organisms under certain conditions, such as during pathogenic colonization when virulence traits are induced by a group of bacteria. In the accompanying paper, Lupp a...
Avian pathogenic E. coli (APEC) caused avian colibacillosis is mostly common in poultry industry worldwide. APEC virulence factors lead to pathogenesis and the quorum sensing (QS) system actively involved regulation of these factors. Signaling molecules QS are known as autoinducers (AIs). In QS-1, encodes a single LuxR homolog, i.e., SdiA, but does not express LuxI an acyl-homoserine lactone (A...
Four Luxi beef cattle (400±10 kg) fitted with ruminal, duodenal and ileal cannulas were used in a 4×4 Latin square to assess the effects of soybean small peptide (SSP) infusion on rumen fermentation, diet digestion and flow of nutrient in the gastrointestinal tract. The ruminal infusion of SSP was 0 (control), 100, 200 and 300 g/d. Ruminal SSP infusion linearly (p<0.01) and quadratically (p<0.0...
