BACKGROUND This study addresses the efficacy of an automated decontamination protocol using the germicide 'tetra acetyl ethylene diamine (TAED) perborate' (Farmec SpA, Italy). The germicide TAED perborate protocol is used in the Castellini Dental Units fitted with an Autosteril unit (an automated device that can cycle 0.26% TAED perborate solution and sterile water for cleaning the water system...

Some years ago?in 1900?Dr. Robert Macguire of the Brompton Consumption Hospital described in a Harveian lecture certain experiments which he had made for the purpose of introducing germicides into the lungs through the venous system, with a view to the destruction of the tubercle bacillus. Previously various trials had been made of various agencies employed in various ways to this end. ''Consum...

A unique agar drum sampler is described which indicates, continuously, the number of viable, bacterial particles per unit volume of air at the time and point of sampling. By selection of the timer and the sampling rate the sampler is suitable for quite a wide range of concentration and time. An impaction line of 484 in. greatly increases the capacity of this device over slit samplers and other ...

This study investigated the feasibility of using Ag-TiO2 photocatalyst supported on glass fiber (Ag-TiO2/GF) prepared by a sol-gel method as an indoor air germicide. An experimental model was designed to investigate the bacterial disinfection efficiency of Staphylococcus (Staph), the most popular bacterium in hospitals in Korea, by the Ag-TiO2/GF photocatalyst. The silver content in Ag/TiO2 was...

Abstract Water treatment, abundant clay in the area, for elimination of particles and microorganisms wastewater disinfection through alcoholic extract molle, which has a high concentration tannins that acts as germicide, not affecting asparagus during cold washing, saving thousands cubic meters groundwater daily. The study explanatory level experimental design. weekly sample (drinking water, re...

In investigations on slow acid development by lactic acid starter cultures,2 only limited consideration has been given to the effect of other bacteria present in the raw milk. Attention has been directed to inhibitory effects of such substances as nisin produced by certain streptococci and to possible inhibition by other bacteria (Cox and Whitehead, 1931; Babel, 1955). However, little specific ...

The evaluation of germicides has been the subject of considerable controversy. At the present time, the phenol coefficient method is the official procedure of the Association of Official Agricultural Chemists (1950) for the evaluation of water-soluble germicides. However, Klarmann and Wright (1946), McCulloch (1947), DuBois (1947), McCulloch, Hauge, and Migaki (1948), and Stuart, Boguskey and F...

The practice of reusing dialyzers has been widespread in the United States for decades, with single use showing signs of resurgence in recent years. Reprocessing of dialyzers has traditionally been acknowledged to improve blood-membrane biocompatibility and prevent first-use syndromes. These proposed advantages of reuse have been offset by the introduction of more biocompatible membranes and fa...
