Observations on a new disinfectant

A new disinfectant.

Qualitative and quantitative tests have been carried out to assess the value of Cidex(1), a glutaraldehyde solution, as a disinfectant. Most of the tests were qualitative and were carried out in conditions as closely resembling those found in hospital practice as possible. Recently used anaesthetic equipment, catheters, and a cystoscope, which had been artificially contaminated with suspensions...

Bactericidal properties of a new water disinfectant.

The N-chloramine compound 3-chloro-4,4-dimethyl-2-oxazolidinone (agent I) has been compared with calcium hypochlorite as to its efficacy as a bactericide for the treatment of water. The study included concentration, contact time, pH, temperature, and water quality as controlled variables. The species of bacteria tested were Staphylococcus aureus, Pseudomonas aeruginosa, and Shigella boydii. In ...

New Observations on Microbodies

The liver of male rats has been studied after CPIB stimulation by using the peroxidase reaction for localizing catalase in hepatic cells. CPIB administration leads to an increase in the number of microbodies, and it is suggested that one mechanism by which microbody proliferation occurs is a process of fragmentation or budding from preexisting microbodies. Reaction product was observed not only...

A new peroxide-based flexible endoscope-compatible high-level disinfectant.

Semicritical medical devices such as flexible endoscopes require high-level disinfection between each use, and glutaraldehyde is often used for this purpose because of its favorable materials compatibility. However, workplace safety and the relatively slow microbicidal activity of such formulations remain a concern. Although recently introduced substitutes based on 0.55% ortho-phthaldehyde (OPA...
