Running Head: Contaminated Germicides

In a series of publications which have appeared during the last five years (1-8), the activity of certain organic compounds, particularly propylene and triethylene glycols, in killing air-borne bacteria and viruses has been described. The types of microorganisms found to be susceptible and some effects on this killing action of changes in the temperature, relative humidity, and concentration of...

1. Certain of the alpha-mercapto soaps and alpha-disulfo soaps are powerful germicides. 2. In the alpha-mercapto series, those soaps with 12 and 14 carbon atoms are most germicidal. In the disulfo series, the dicaprate, dilaurate, and dimyristate are most germicidal. The optimum number of carbon atoms varies with the test organism used. 3. These soaps, like others previously studied, show a mar...

The effect of leaf extracts of Psidium guajava and Piper betle on prolonging vase life of cut carnation flowers was studied. "Carola" and "Pallas Orange" carnation flowers, at bud stage, were pulsed 24 hours with a floral preservative. Then, flowers were placed in a vase solution containing sprite and a "germicide" (leaf extracts of P. guajava and P. betle, 8-HQC, or a copper coin). Flowers tre...

Two years ago I brought before this Society what I thought to be strong arguments in favour of the substitution of cotton wool impregnated with a non-volatile antiseptic for the carbolic gauze commonly in use in the treatment of recent wounds. A year ago I related also to this Society a series of experiments which led me to believe that the spray of carbolic acid was useful only in so far as it...

The inactivation of virus-contaminated nonporous inanimate surfaces was investigated using adenovirus type 8, a common cause of epidemic keratoconjunctivitis. A 10-microl inoculum of adenovirus was placed onto each stainless steel disk (1-cm diameter), and the inoculum was allowed to air dry for 40 min. Twenty-one different germicides (including disinfectants and antiseptics) were selected for ...
