Hand washing is viewed as the most important barrier to cross infection. Incorrect use of clinical hand wash basins may lead to cross infection either from contaminated water or due to failure to decontaminate hands. Elbow operated taps used correctly prevent re-contamination of hands during operation. Observation shows many elbow operated taps are installed incorrectly with the handle flush with the back panel making it difficult to open using the elbow. AIM: To determine the effect of altering the angle of the handle of elbow operated taps on hand washing technique...

BACKGROUND: Control of foodborne pathogens is an important issue for the fruit juice industry and ohmic heating treatment has been considered as one of the promising antimicrobial interventions. However, to date, evaluation of the relationship between inactivation of foodborne pathogens and system performance efficiency based on differing soluble solids content of apple juice during ohmic heating treatment has not been well studied. This study aims to investigate effective voltage gradients of an ohmic heating system and corresponding sugar concentrations (°Brix) of apple juice for inactivating major foodborne pathogens (E...

The chemical decontamination of infected dental implants is essential for the successful treatment of peri-implantitis. The aim of this study was to assess the antibacterial effect of a hydrogen peroxide-titanium dioxide (H2O2-TiO2) suspension against Staphylococcus epidermidis biofilms. Titanium (Ti) coins were inoculated with a bioluminescent S. epidermidis strain for 8 h and subsequently exposed to H2O2 with and without TiO2 nanoparticles or chlorhexidine (CHX). Bacterial regrowth, bacterial load and viability after decontamination were analyzed by continuous luminescence monitoring, live/dead staining and scanning electron microscopy...

To decontaminate heavy metal-containing waste water, a microbial biotechnology was developed by using the synergy between Sulfate reducing bacteria (SRB), Bacillus cereus (B. cereus) and Camellia oleifera cake (COC). In this process the COC degradation assisted by B.cereus, created an anoxic environment and provided energy and nutrition for SRB. Both of B. cereus and SRB played significant roles through biosorption, bioaccumulation and biosurfactant production. Meanwhile, a flotation technology commonly used in many effluent treatments has been led into this system for increasing the efficiency as well...

The disinfection effect of slightly acidic electrolyzed water (SAEW) use in a farm where Pseudomonas mastitis has spread was evaluated. Despite the application of antibiotic therapy and complete cessation of milking infected quarters, numerous new and recurrent Pseudomonas aeruginosa clinical mastitis infections (5.8-7.1% of clinical mastitis cases) occurred on the farm from 2003 to 2005. Procedural changes and equipment modifications did not improve environmental contamination or the incidence of Pseudomonas mastitis...

BACKGROUND: Surgical site infection rates in the month following surgery vary from 1% to 5%. Due to the large number of surgical procedures conducted annually, the costs of these surgical site infections (SSIs) can be considerable in financial and social terms. Nasal decontamination using antibiotics or antiseptics is performed to reduce the risk of SSIs by preventing organisms from the nasal cavity being transferred to the skin where a surgical incision will be made. Staphylococcus aureus (S aureus) colonises the nasal cavity and skin of carriers and can cause infection in open or unhealed surgical wounds...

Animal-origin food products pose serious threat to public food safety due to high microbial loads. The microbial and radioactive contaminations in commercial cold duck meat products were evaluated. Ten different lots of commercial samples (C1-C10) were classified based on type and smoking process. All samples were highly contaminated (< 4-7 Log CFU/g) with total aerobic bacteria (TAB), yeasts and molds (Y&M), and 7 samples (C1-C7) were positive for coliforms. Furthermore, three samples were contaminated with Listeria monocytogenes (C4-C6) and one with Salmonella typhimurium (C6)...

Sarin is a potent nerve agent chemical weapon that was originally designed for military purposes as a fast-acting anti-personnel weapon that would kill or disable large numbers of enemy troops. Its potent toxicity, ease of deployment, and rapid degradation allow for rapid deployment by an attacking force, who can safely enter the area of deployment a short while after its release. Sarin has been produced and stockpiled by a number of countries, and large quantities of it still exist despite collective agreements to cease manufacture and destroy stockpiles...

The mortality for carbapenem-resistant Klebsiella pneumoniae (KPC-Kp) infection ranges from 18 to 48% depending on the type of therapy. Mortality rates in hematologic patients are even higher, up to 85%. Gut decontamination with oral gentamicin might be an option to avoid a subsequent KPC-Kp infection in colonized patients. We treated 14 hematologic patients with oral gentamicin, 80 mg four times daily, for 7 to 25 days in order to eradicate KPC-Kp from the gut, starting oral gentamicin therapy when possible after the discontinuation of systemic antibiotic therapy...

Geobacillus stearothermophilus spores on stainless steel discs are routinely used as Biological Indicators (BIs) for the validation of hydrogen peroxide bio-decontamination processes. Given ongoing concerns about the reliability and response time of BIs, we explored the potential for an enzyme-based approach decontamination process evaluation. Thermostable adenylate kinase (tAK) enzyme was coated onto a solid support and exposed to hydrogen peroxide vapour, in parallel with standard commercial 6-log BIs, during a series of vapour-phase hydrogen peroxide (VPHP) cycles in a flexible film isolator...

INTRODUCTION: Guttapercha (GP) cones are usually supplied in aseptic, sealed packages from the manufacturers, but once exposed to the dental office environment or even by handling; they can be contaminated by a number of microorganisms. Supplementary decontamination of GP cones is critical. As they cannot be sterilized by moist or dry heat, cold sterilization, using disinfectants should be used. AIM: The aim of the study was to evaluate rapid, reliable, convenient and effective method of disinfection of GP cones using readily available herbal solutions such as Aloevera Juice, Amla Juice and Pancha Tulsi...

Chronic wounds are a major socio-economic problem. Bacterial infections in such wounds are a major contributor to lack of wound healing. An early indicator of wound infection is an increase in pH of the wound fluid. Herein, we describe the development of a pH-responsive drug delivery device that can potentially be used for wound decontamination in situ and on-demand in response to an increase in the pH of the wound environment. The device is based on a porous silicon film that provides a reservoir for encapsulation of an antibiotic within the pores...

Damage control surgery (DCS) and resuscitation has improved the survival of trauma patients with decompensated physiology. In recent years, the principles of DCS have been used in the treatment of patients with abdominal sepsis, despite the fact that only a minimum of evidence exists. The aim is to optimize the physiology prior to definitive surgery. This implies a primary decontaminating surgical procedure with temporary abdominal closure without restoration of the intestinal continuity and avoidance of stoma formation in order to reduce time in the operating theatre...

Degradation and body surface decontamination is vital to prevent the skin penetration of paraoxon (POX), an organophosphorus pesticide, and victims poisoning. CeO2 demonstrated a good efficacy for the degradation of POX. The aim of the study was to develop a model which includes the impact of weight of CeO2, POX and diluent volumes on the degradation kinetics. The modelling was realized with rapid and simple experiments carried out in tubes, in aqueous diluent which contained ions in order to be in accordance with in vitro skin decontamination conditions...

Water decontamination from As(III) is an urgent but still challenging task. Herein, we fabricated a bifunctional nanocomposite HFO@PS-Cl for highly efficient removal of As(III), with active chlorine covalently binding spherical polystyrene host for in situ oxidation of As(III) to As(V), and Fe(III) hydroxide (HFO) nanoparticles (NPs) embedded inside for specific As(V) removal. HFO@PS-Cl could work effectively in a wide pH range (5-9), and other ubiquitous anions like sulfate, chloride, bicarbonate, and silicate exert insignificant effect on As(III) removal...

Skin contamination with radionuclides may cause local radiation damage, but also systemic distribution if the nuclides penetrate the epidermal membrane. Detailed information of the skin absorption of radionuclides is of importance for e.g. dose estimations and development of decontamination strategies. In the present study, penetration of (131)I through human epidermis was studied using an in vitro flow through diffusion chamber. Epidermis was exposed to a Na(131)I-solution, used in nuclear medicine, and the potential concentration-dependency of skin penetration was examined by including two concentrations of non-radioactive NaI...
