The virulent capacity of Pseudomonas aeruginosa can largely be ascribed to quorum sensing, i.e. the ability to evade host defence by a coordinated production and secretion of virulence factors.

We analysed markers of systemic immune response in patients with chronic venous leg ulcers (CVLUs) colonised (no-systemic infection) with the opportunistic pathogen Pseudomonas aeruginosa. Sera from 44 clinically non infected patients with CVLUs were analysed for total IgM and IgG isotype 1-4, complement C3, mannose-binding lectin (MBL), interleukin (IL)-6, C-reactive protein (CRP) and specific anti-P.

However, the function of the αvβ6 integrin in wound repair remains unclear. Impaired wound healing in patients with diabetes constitutes a major clinical problem worldwide and has been associated with the accumulation of advanced glycated endproducts (AGEs) in the tissues.

Worldwide, Streptococcus pneumoniae (pneumococcus) is a major cause of morbidity and mortality, especially in infants and elderly people. Pneumococcal capsular polysaccharides are well characterized, and more than 90 different serotypes have been identified. Serotype-specific antibodies against the capsular polysaccharide are produced during infection.
