This study compared the sensitivity of spores from virulent and attenuated Bacillus anthracis strains in suspension to inactivation by various chemical disinfectants. Spore suspensions from two virulent strains (A0256 and A0372) and two attenuated strains (Sterne and A0141) of B. anthracis were tested against two aldehyde-based disinfectants and one hypochlorite-based disinfectant. A novel stat...

Large quantities of disinfectants are used in hospitals, externally on human skin or to eliminate microorganisms from inanimate objects. After use, residual quantities of these products reach the wastewater, exposing the bacteria that survive in hospital wastewaters to a wide range of biocides that could act as a selective pressure for the development of resistance. Increasing attention has bee...

BACKGROUND Directive 98/8/EC harmonizes and regulates in the European market authorization and registration of biocides and establishes a period of 14 years for review of active substances. This study analyzes the most significant changes produced in the registry of biocides used as disinfectants registered since the publication of the Directive. METHOD Information was obtained from the regis...

In an effort to evaluate and control the potential hazard and inherent risk of environmental transmission and spread of nosocomial infections by contact with hitherto “non-critical” inanimate/environmental surfaces in the hospital and healthcare facilities (commode, bed, bowl of toilet etc.), the microbicidal efficacies of six disinfectants products commonly used in local hospital facilities wa...

This study investigated (1) the susceptibility of Bacillus anthracis (Ames strain), Bacillus subtilis (ATCC 19659), and Clostridium sporogenes (ATCC 3584) spores to commercially available peracetic acid (PAA)- and glutaraldehyde (GA)-based disinfectants, (2) the effects that heat-shocking spores after treatment with these disinfectants has on spore recovery, and (3) the timing of heat-shocking ...

One of the most common pathogens in infection of hydrogel contact lens wearers is Pseudomonas aeruginosa, which can gain access to the eye via contamination of the lens, lens case, and lens care solutions. Only one strain per species is used in current regulatory testing for the marketing of chemical contact lens disinfectants. The aim of this study was to determine whether P. aeruginosa strain...

Chytridiomycosis, a disease contributing to amphibian declines worldwide, is caused by the fungus Batrachochytrium dendrobatidis. Identifying efficient and practical disinfectants effective against B. dendrobatidis is important to reduce the spread of the disease both in the wild and captivity. Previous studies identified a range of suitable disinfectant strategies. We evaluated the suitability...

BACKGROUND Central dialysate fluid delivery systems (CDDS) are used by dialysis centers in Japan, and although these systems are effective at delivering dialysate, they have a complex piping network with numerous sites where contamination can develop. In Japan, cleaning disinfectants have been clinically evaluated based on endotoxin levels and bacterial counts, but there have been no published ...

background and aims. several products have been marketed for disinfecting impression materials. the present study evaluated the effect of deconex, micro 10, alprocid and unisepta plus sprays on staphylococcus aureus and candida albicans transferred to alginate and polyvinylsiloxane impression materials. materials and methods. a total of 180 impressions of a maxillary model (90 alginate and 90 p...
