The role of Staphylococcus aureus sortase A and sortase B in murine arthritis.

Gram-positive pathogenic bacteria display proteins on their surface that play important roles during infection. In Staphylococcus aureus, these surface proteins are anchored to the cell wall by two sortase enzymes, SrtA and SrtB, that recognize specific surface protein sorting signals. The role of sortase enzymes in bacterial virulence was examined using a murine septic arthritis model.

On the role of Staphylococcus aureus sortase and sortase-catalyzed surface protein anchoring in murine septic arthritis.

Anchoring of Staphylococcus aureus surface protein to the cell wall is catalyzed by sortase, a transpeptidase. The contribution of staphylococcal surface proteins to establishment of infection was examined using a murine septic arthritis model. Intravenous inoculation of mice with the sortase-deficient mutant S.

Lower level of education in young adults with arthritis starting in the early adulthood.

An appropriate education may lead to less work disability in patients with arthritis. The aim of the study was to determine the educational level in two groups of young adults with arthritis. Patients with juvenile arthritis ( JA, n=32) and patients with early adult onset of arthritis (EA, n=47) were examined with the Quality of Life Scale (QOLS) and a questionnaire concerning education and profession counselling.

Disturbed grip function in women with rheumatoid arthritis.

Objective: Hand dysfunction is a frequent cause of disability in rheumatoid arthritis (RA). In patients with RA, we studied the precision grip-lift sequence in relation to pain, stiffness, and observer assessed hand function and their relation to patients' experience of clumsiness and tendency to drop objects.

Methods: Performance of the precision grip-lift sequence was studied in 23 women with RA and 7 age and sex matched controls.
