Acute bacterial, nonnecrotizing cellulitis in Finland: microbiological findings.

Background: Bacterial, nonnecrotizing cellulitis is a localized and often recurrent infection of the skin. The aim of this study was to identify the beta-hemolytic streptococci that cause acute nonnecrotizing cellulitis infection in Finland.

Methods: A case-control study of 90 patients hospitalized for acute cellulitis and 90 control subjects was conducted during the period of April 2004-March 2005.

Transient absorption and photovoltage study of' self-assembled bacteriorhodopsin/polycation multilayer films.

A series of organized (PDAC/PM)(n) (poly(diallyldimethylammonium chloride)/purple membrane) multilayer films were prepared by alternate adsorptions of positively charged PDAC polyelectrolyte and negatively charged purple membrane (PM). The kinetics of the photocycle of bacteriorhodopsin (bR) in PM was studied by flash photolysis and transient photovoltage methods. Although the orientation of the adsorbed bR depends on the pH of the PM suspension, the kinetics of the photo-induced reaction cycle in dehydrated films is independent of the deposition pH.
