Management of nosocomial scabies, an outbreak of occupational disease.

Background: The optimal approach to managing institutional scabies outbreaks has yet to be defined. We report on outbreak managements are needed.

Methods: We report on a large outbreak of scabies in three acute care wards in a tertiary university teaching hospital in the Netherlands.

Requirement of signal peptidase ComC and thiol-disulfide oxidoreductase DsbA for optimal cell surface display of pseudopilin ComGC in Staphylococcus aureus.

Staphylococcus aureus is an important Gram-positive bacterial pathogen producing many secreted and cell surface-localized virulence factors. Here we report that the staphylococcal thiol-disulfide oxidoreductase DsbA is essential for stable biogenesis of the ComGC pseudopilin. The signal peptidase ComC is indispensable for ComGC maturation and optimal cell surface exposure.

High genetic diversity of Staphylococcus aureus strains colonizing patients with epidermolysis bullosa.

Patients with the blistering disease, epidermolysis bullosa (EB), frequently suffer from chronic wounds that become colonized by pathogenic bacteria, such as Staphylococcus aureus. To determine S. aureus colonization rates in patients with EB, swabs were collected from the anterior nares, throats and wounds of 52 Dutch patients with EB.
