Abstract

Clostridium perfringens is a major enteric pathogen that is responsible for causing necrotic enteritis of poultry. The ability to adhere to the host's intestinal epithelium and to extracellular matrix molecules (ECMM) in the gut, are strategies used by numerous bacterial enteropathogens, however, C. perfringens has received comparatively little attention in this respect. The present study investigated sixteen type A C. perfringens isolates from chickens, with varying disease producing ability with respect to necrotic enteritis in chickens, for their ability to adhere to nine different extracellular matrix molecules (ECMM) and to the intestinal epithelial cell line Caco-2. C. perfringens strains were able to bind to ECMMs and there was strain variation. Strains of C. perfringens that produced severe disease, were capable of binding to collagen type III, IV and V, fibrinogen, laminin and vitronectin at higher levels than less severe disease producing strains, suggesting that the ability to adhere to ECMMs might enhance virulence with respect to induction of necrotic enteritis. In addition, severe disease producing strains also bound better to collagen type III and IV and fibrinogen, than non-disease producing strains. The present...Continue Reading

Basement Membranes

Basement membranes are thin, specialized extracellular matrices surrounding most tissues in all metazoans. Here is the latest research on basement membranes.

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.
