tipped swab (Fisher Scientific) premoistened in Dey-Engley neutralizer (Becton Dickinson). The swabs were vortexed for 45 seconds in 200 piL of Dey-Engley neutralizer, plated onto prereduced C. difficile Brucella agar (CDBA), and cultured as previously described. For the fresh Clorox premoistened germicidal wipes only, an additional experiment was performed in which the inoculated site was wipe...

The rapid spread of quagga mussels (Dreissena rostriformis bugensis) has lead to their invasion of Lake Mead, Nevada, the largest reservoir in North America and partially responsible for providing water to millions of people in the southwest. Current strategies for mitigating the growth and spread of quagga mussels primarily include physical and chemical means of removing adults within water tr...

A new principle in compounding stable, granular bactericidal products led to unique combinations of a water-soluble inorganic bromide salt with a hypochlorite-type disinfectant of either inorganic or organic type. Microbiological results are shown for an inorganic bactericide composed of chlorinated trisodium phosphate containing 3.1% "available chlorine" and 2% potassium bromide, and for an or...

Cleaning and drying a surface with a non-germicidal detergent is effective against some pathogens, but not all. Pathogens like Salmonella and toxigenic E. coli (gram-negative microorganisms) are generally adapted to wet environments, and so an initial removal is achieved when the surface is wiped and then drying helps to kill more germs – but this takes time and one can’t count on drying to rem...
