Background and Objectives :Microorganisms including Fungi, are among air-transmitted infectious agents at hospitals and patient care settings, which in addition to patients, can afflict Health Care Workers (HCWs) and visitors, and may results in extravagant economic burden and impact on human health. Use of nanotechnology and especially nanosilver particles is one of the methods which are used ...
Cleaning Failure to adequately clean instrument results in higher bioburden, protein load, and salt concentration. These will decrease sterilization efficacy. Bioburden The natural bioburden of used surgical devices is 10 to 10 organisms (primarily vegetative bacteria), which is substantially below the 10-10 spores used with biological indicators. Pathogen type Spore-forming organisms are most ...
Background: A topical antimicrobial that can decrease the bacterial bioburden of chronic wounds without impairing the wound's ability to heal is a therapeutic imperative. A stabilized form of hypochlorous acid (NVC-101) has been demonstrated in vitro and in standard toxicity testing to possess properties that could fulfill these criteria. Materials and Methods: Using a standard rodent model of ...
OBJECTIVE We examined associations between ulcer bioburden and ulcer outcomes in neuropathic diabetic foot ulcers (DFUs) that lacked clinical signs of infection. RESEARCH DESIGN AND METHODS Three dimensions of bioburden (i.e., microbial load, microbial diversity, and the presence of likely pathogens) were measured at baseline using swab cultures obtained by Levine's technique. Subjects were a...
BACKGROUND Expressed human milk (EHM) feed preparation areas represent a potential source of unintentional nosocomial infection. Daily disinfection of environmental surfaces remains an essential intervention to mitigate nosocomial infections. The inefficiency of conventional cleaning and disinfection contributes to an increased risk for the acquisition of multi-drug resistant pathogens. "Non to...
OBJECTIVE To determine the in vivo effect of a sustained-release silver sulphadiazine powder foam dressing on the bacterial burden of venous leg ulcers (VLUs), with a view to correlating the wound closure rate with the degree of bioburden and to assess other markers of its progression towards healing. METHOD Patients attending a tertiary care wound practice were screened for a VLU bacterial c...
Decontamination and cleaning protocols are critical in reprocessing medical device. Protocols should be designed to remove biological debris, reduce bioburden and minimize the risk for health professionals. These issues are of utmost importance when reprocessing of single-use-only labeled devices is considered. This study evaluates the efficiency in reducing bioburden of four protocols for deco...
