The possibility of immobilization of Acetobacter suboxydans cells by entrapment within polyacrylamide gels or by intercellular cross-linking with glutaral-dehyde was investigated. The oxidation of unsubstituted alditols and aldose diethyl dithioacetals by the resultant modified cells has been achieved.

BACKGROUND The emergence of Clostridium difficile ribotype 027 raised the question of sporicidal surface disinfectants are also effective against spores of C. difficile ribotype 027. MATERIALS AND METHODS Three surface disinfectants based on magnesium monoperoxyphthalate hexahydrate (Dismozon pur), a combination of (ethylenedioxy)dimethanol, glutaral and benzyl-C12-18-alkyldimethylammonium ch...

For surface disinfection in hospitals and nursing homes, preparations containing aldehydes such as formaldehyde, glutaral, or glyoxal, as well as quaternary ammonium compounds (QACs), are being used. Occupational allergic contact dermatitis (OACD), including airborne dermatitis, caused by these compounds is a well-known problem in nurses and hospital cleaners (1–6). For diagnostic purposes, onl...

glutaraldehyde is commonly used in endoscopy labs to clean and disinfect instruments. it can cause direct irritation of the skin and the upper and lower airways. health care workers are also at risk for the development of irritant-induced or sensitizer-induced occupational asthma when exposed to this chemical. herein, we report on a patient who had frequent exposures to glutaraldehyde over one ...

Objective: To evaluate a possible synergic effect of the most promising anti-calcifying agents investigated in the literature by sequential treatment. Method: Glutaraldehyde-fixed bovine pericardium was treated by: heating to 50o C, 80% ether, 0.125% chitosan, heparin, NaBH4 and 4% formaldehyde. Samples were evaluated by optic microscopy, shrinking and mechanical tests and implanted subcutaneou...

To evaluate disinfection methods for environments contaminated with bioterrorism-associated microorganism (Bacillus anthracis), we performed the following experiments. First, the sporicidal effects of sodium hypochlorite on spores of five bacterial species were evaluated. Bacillus atrophaeus was the most resistant to hypochlorite, followed in order by B. anthracis, Clostridium botulinum and Clo...

Ultrastructural studies of gliding bacteria demonstrate 10- to 11-nm beads on the inner surface of the outer bilayer of Cytophaga columnaris. These were not found in Myxococcus xanthus. On treatment with glutaraldehyde and ethanol, the beads appear in linear arrays.

Sheep erythrocytes were treated with glutaraldehyde before sensitization for the indirect hemagglutination test to assay chlamydial antibodies. This treatment markedly increased stability during storage.

A study on the rate of inactivation by glutaraldehyde of coxsackievirus was conducted using different concentrations, temperatures, and pH values. It was found, that 2 percent glutaraldehyde at pH 7.4 and 25 C, as recommended for a sporicide, reduced the titer of infectious virus by 2 log10U in 1 min or less. The reduction was not negatively affected by high concentrations of organic matter (se...
