Disinfecting apparatus

New disinfecting apparatus for gastrointestinal fibre-endoscopes.

Bacterial contamination of gastrointestinal fibre-endoscopes is a potential source of clinically significant infection. Aqueous 2% alkaline glutaraldehyde adequately disinfects fibre-endoscopes but may cause serious sensitivity reactions among endoscopy staff. A new 'closed-system' disinfecting apparatus is described that disinfects with glutaraldehyde for 30 minutes before an endoscopy session...

On McDougall's Disinfecting Powder

On the 14th July were admitted into the jail hospital fourteen men, victims of an accident at a brick-kiln, by which burns of a most severe nature were inflicted. Many of these men had complete desquamation of the greater part of the cuticle of the legs and arms?the skin, equal in some cases to one-fourth of the entire surface, being destroyed. Of these men seven died from their wounds. My obje...

Fast disinfecting antimicrobial surfaces.

Silicon wafers and glass surfaces were functionalized with facially amphiphilic antimicrobial copolymers using the "grafting from" technique. Surface-initiated atom transfer radical polymerization (ATRP) was used to grow poly(butylmethacrylate)-co-poly(Boc-aminoethyl methacrylate) from the surfaces. Upon Boc-deprotection, these surfaces became highly antimicrobial and killed S. aureus and E. co...

D-value determinations are an inappropriate measure of disinfecting activity of common contact lens disinfecting solutions.

Determination of a D value for specific test organisms is a component of the efficacy evaluation of new contact lens disinfecting solutions. This parameter is commonly defined as the time required for the number of surviving microorganisms to decrease 1 logarithmic unit. The assumption made in establishing a D value is that the rate of kill exhibits first-order kinetics under the specified cond...
