The currently used microbial decontamination method for spacecraft and components uses dry-heat microbial reduction at temperatures of >110°C for extended periods to prevent the contamination of extraplanetary destinations. This process is effective and reproducible, but it is also long and costly and precludes the use of heat-labile materials. The need for an alternative to dry-heat microbial ...

Several decontamination agents including water, sodium hypochlorite, peroxyacetic acid, neutral electrolyzed oxidizing water, and chlorine dioxide gas were tested for their effectiveness to reduce the natural microflora on grated carrots. Microbial reductions of the total aerobic count obtained after the different treatments varied between 0.11 and 3.29 log colony-forming units (cfu)/g. Whether...

Mycobacterium avium subsp. paratuberculosis (MAP) is the causative agent of Johne's disease in cattle and it has been suggested that this organism may be associated with Crohn's disease in humans. Cows at the advanced stage of the disease shed this organism into both their milk and feces. The objective of this study was to develop a more efficient procedure for isolating MAP from bulk tank raw ...

The incidence of central venous access device (CVAD)–associated bloodstream infection (CABSI) has been reported to be as high as 21%. Inadequate needleless connector decontamination can result in microbial contamination of the CVAD internal lumen, resulting in device colonization and CABSI. Guidelines vary in recommendations for antiseptic type and duration of application to needleless connecto...

Low temperature Plasma (LTP) is a high-energy gas that is created when an electrical current is passed through a gas. Until recently, plasmas could only be created at relatively high temperatures in a vacuum and the use of plasma on sensitive materials such as human tissue, food products, medical devices and the packaging industry, was therefore impractical. However, over the last few years tec...

by certain fungi belonging to the genus Aspergillus spp and can occur as natural contaminants of poultry food [1]. Aflatoxicosis in poultry causes listlessness, anorexia with lowered growth rate, poor food utilization, decreased weight gain, decreased egg production, increased susceptibility to environmental and microbial stresses, and increased mortality [2]. Also associated with aflatoxicosis...

In this work effects of gamma irradiation and storage time on microbial decontamination of fresh camel meat stored at 4 ̊C were evaluated. Microbial analysis indicated that irradiation had a significant effect on the reduction of microbial loads. Among the analyzed bacteria, coliforms were most sensitive to gamma radiation. Considering the sensory analyses and Total bacterial counts analyses as ...

BACKGROUND A frequent problem in dental units is the microbial contamination of water and biofilm formation in the water supply lines. After random identification of a bacterial contaminated dental unit (310 cfu/ml) in a practise with 3 dental units we implemented the present study to evaluate the efficacy of the PotoClean(®) technology, based on anodic oxidation. METHOD The efficacy of a reg...

OBJECTIVE To evaluate the efficacy of ultraviolet (UV) irradiation for rapid microbial decontamination of liquid nitrogen (LN2). DESIGN Basic research. SETTING Private assisted reproduction center. ANIMAL(S) Microorganisms (bacteria and fungi). INTERVENTION(S) Two stainless steel open dewars containing LN2 were contaminated in a two-step experiment with high titers of cultures of bacter...
