A non‐coding RNA from the intercellular adhesion (ica) locus ofStaphylococcus epidermidiscontrols polysaccharide intercellular adhesion (PIA)‐mediated biofilm formation

Biofilm formation and the presence of the intercellular adhesion locus ica among staphylococci from food and food processing environments.

In clinical staphylococci, the presence of the ica genes and biofilm formation are considered important for virulence. Biofilm formation may also be of importance for survival and virulence in food-related staphylococci. In the present work, staphylococci from the food industry were found to differ greatly in their abilities to form biofilms on polystyrene. A total of 7 and 21 of 144 food-relat...

Detection of Intracellular Adhesion (ica) and Biofilm Formation Genes in Staphylococcus aureus Isolates from Clinical Samples

Background: The nosocomial infections that cause the establishment of biofilms on the embedded biomedical surfaces are the leading cause of sepsis and are often related to colonization of implants by Staphylococcus epidermidis. Materials and Methods: A total of 40 clinical S. aureus isolates were collected from Zabol, Iran. The ability of these strains to form biofilm was determined by microli...

Soluble Intercellular Adhesion Molecule

Previous studies have suggested that intercellular ad¬ hesion molecule 1 (ICAM-1, CD54) may be involved in the pathogenesis ofasthma. In addition, a soluble form of ICAM-1 (sICAM-1) has been detected in increased concentrations in the sera of patients with certain in¬ flammatory conditions. To determine whether bron¬ chial asthma is associated with increased levels of sICAM-1 in serum and to as...

Genetic regulation of the intercellular adhesion locus in staphylococci

The formation of biofilms by Staphylococcus aureus and Staphylococcus epidermidis is an important aspect of many staphylococcal infections, most notably endocarditis, osteomyelitis and infections associated with indwelling medical devices. The major constituents of staphylococcal biofilms are polysaccharides, such as poly N-acetyl glucosamine (PIA/PNAG), cell surface and secreted bacterial prot...
