Abstract

This study reports the probiotic attributes of Lactobacillus strains isolated from chicken faeces and mainly their capabilities to prevent infectious diseases and improve chicken production performance. Thus, 22 Lactobacillus strains were isolated from 50 chickens' faeces samples and assessed for their resistance to gastric acidity (pH 0.5, 1, 1.5, 2 and 2.5), tolerance to bile salts, adherence to broiler intestinal cells and antibacterial activity. These in vitro screening analyses revealed Lactobacillus plantarum S22 and L. plantarum S27 as the only strains capable to survive at pH 2.0 in MRS broth (log10 cfu/ml=5.02 and 8.46 log respectively), while the remaining strains were not resistant to pH≤2.0. Similarly, 21 strains were resistant to bile at 0.5% (log10 cfu/ml=0.09-3.32 log), but only Lactobacillus fermentum S26, L. plantarum S22 and L. plantarum S27 were able to grow in the presence of 0.1% (w/v) bile (8.23±0.15; 8.39±0.17 and 8.57±0.07 respectively). Most of these isolates (19/22) were active against Escherichia coli ATCC 25922, E. coli SL2016 and Salmonella enterica CIP 81-3. Lactic acid is likely the main antibacterial compound produced since the neutralised supernatant was devoid of any antibacterial activity. In ...Continue Reading

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.
