Bacterial vaginosis – Excessive 'bad' bacteria in the vagina Fatigue testing – Testing of a medical device to determine its resistance to stress Fc – The region of an antibody at the bottom of the protein's 'Y' shape Metal oligomers in MixGo binds to antibodies via the Fc region resulting in uniform surface orientation for the antibodies in a MixGo-enabled immunoassay


and bacterial filtration efficiency (BFE) of treated and untreated surgical gowns The results show that hot steam autoclaving at the stipulated standard temperature and pressure is adequate to render a surgical gown fit for re-use in the operating theatre However the strike through properties (1 88-2 36sec) and the BFE of untreated and treated surgical gowns of 19 2% and 35 56% respectively

Australian Guidelines for the Prevention and Control of

Synopsis There are around 200 000 healthcare-associated infections (HAIs) in Australian acute healthcare facilities each year This makes HAIs the most common complication affecting patients in hospital As well as causing unnecessary pain and suffering for patients and their families these adverse events prolong hospital stays and are costly to the health system

How Surgical Masks are Made Tested and Used

Bacteria filtration efficiency in vitro (BFE) This test works by shooting an aerosol with staphylococcus aureus bacteria at the mask at 28 3 liters per minute This ensures the mask can catch the percentage of bacteria it's supposed to Particle Filtration Efficiency Also known as the latex particle challenge this test involves spraying an aerosol of polystyrene microspheres to ensure the

Dry Heat Ovens Can Effectively Disinfect N95 Masks

The initial testing on the 1860 model was at 250˚F (121˚C) for a duration of 60 minutes with a 30-minute ramp down and a 5˚C deviation These masks failed the qualitative fit test by EHS following this soak We then decided that temps were likely higher than they needed to be and cycles were too long The next attempt used the 1870 model N95's at 250˚F for 60 minutes These masks passed

Improved multiple displacement amplification (iMDA) and

A specialized ethylene oxide treatment was developed that renders free DNA and DNA present within Gram positive bacterial cells undetectable by qPCR To reduce DNA contamination in amplification reagents a combination of ion exchange chromatography filtration and lot testing protocols were developed Our multiple displacement amplification

These usually consist of highly resistant bacterial spores (e g spores fromGeobacillus or Bacillus species) that are only killed when adequate sterilisation conditions (i e time temperature and steam pressure) are reached If the high-density spore preparations found in biological indicators are killed following a sterilisation cycle this indicates that other microorganisms present in the


This is known as TYNDALLISATION or INTERMITTENT STERILISATION 56 oral mucosa and nasal mucosa Masks should have 95% filtration efficiency of 3 to 5m in diameter Should be changed for each patient Chin length face shield may be worn 114 115 115 116 No contact with the wearers lips and nostrils Has a high bacterial filtration efficiency rate Fit snugly No fogging of eye wear Convenient
