Inhibition of adhesion of Escherichia coli K88 to piglet ileal mucus by Lactobacillus spp

Article Abstract:

The interference of lactobacillus metabolites to the adhesion of Escherichia coli K88 in the gastrointestinal ecosystem is discussed. An in vitro adhesion assay was used on porcine lactobacillus-produced metabolites acting on the adhesion mechanism of K88 fimbria-bearing cells. It was found that the adhesion of K88-bearing cells are reduced due to the mucus affecting proteinaceous component released into the culture supernatant by the lactobacillus metabolites.

Presence of active and inactive molecules of a cell wall-associated proteinase in Lactobacillus helveticus CP790

Article Abstract:

Immunoblotting analysis of the cell wall extract of Lactobacillus helveticus CP790 using monoclonal antibodies reveals that the antibodies react with both the 45-kDa proteinase and an unidentified 46-kDa protein. Column chromatography helps purify the 46-kDa protein and the 45-kDa proteinase. Significant similarity between the 45-kDa proteinase and 46-kDa protein indicates the 46-kDa protein to be an inactive form of the 45-kDa proteinase.

Carbon catabolite repression in Lactobacillus pentosus: analysis of the ccpA region

Article Abstract:

The ccpA gene of Lactobacillus pentosus has two promoters, which probably allows the gene to be active under diverse environmental conditions. The gene produces a protein similar to the CcpA catabolite control protein in other bacteria.
