Vapor-based fumigant system could prove useful in disinfecting microbiology labs, clinical labs, and histology labs
There’s a new technology that bears great promise for improving existing methods of disinfecting hospital rooms and health facilities, including clinical laboratories. This pioneering work was developed as part of a collaboration involving infection control expert Dick Zoutman, M.D., FRCPC, who is affiliated with Queen’s University of Kingston, Ontario, Canada.
This technology is a vapor-based fumigant system and is coming to market with the name AsepticSure. It will be sold by Medizone International, Inc.. The invention makes a strong argument for changing the way hospital rooms and other healthcare facilities are disinfected. (more…)

Use of plasma technology will give healthcare workers another way to clean their hands
Even Buck Rogers and Flash Gordon would be amazed to learn that plasma technology is about to deliver a way for healthcare workers to sanitize their hands without using soap and water! Pathologists and clinical laboratory managers will be interested to learn about a novel device that bathes hands with plasma as a way to reduce the spread of microorganisms by healthcare workers, including superbugs like MRSA, an antibiotic-resistant strain of Staphylococcus aureus.
Prototypes already exist and are designed to be simple for healthcare workers to use. They would simply stick their hands into a small box that bathes the hands with plasma that is specifically engineered to zap bacteria, viruses and fungi. The plasma used in the hand sanitizer is a gas similar to that used in fluorescent lights, neon signs, and televisions, but works at room temperature and pressure.

Human Microbiome Project is expected to trigger many new molecular diagnostic assays
Meet the human microbiome, considered by some medical researchers to be the newest biomedical frontier. A major effort to map the human microbiome is expected to identify a significant number of new biomarkers that will be useful in both clinical pathology diagnostic tests and therapeutic drug development.
Known as the Human Microbiome Project, the five-year program is funded with $115 million in grants from the National Institutes of Health (NIH). Researchers are well on their way to produce a comprehensive inventory of microbes—bacteria, viruses, yeast and fungi—that live in or on the human body, along with information about their role in disease development or prevention. The overall goal of this international effort is to identify which microbes are harmful and figure out ways to prevent or treat diseases they cause.

Researchers say Mobidiag’s microarray-based diagnostic test technology looks promising
There’s a new DNA-based microarray platform that could speed identification of blood-borne pathogens. By allowing clinical laboratories to deliver test results in just 18 hours, use of this new microarray could improve early detection and management of sepsis patients.
In a study headed by Päivi Tissari, M.D., of the Division of Clinical Microbiology, Helsinki University Hospital Laboratory in Finland, the Prove-it sepsis assay, manufactured by Helsinki-based Mobidiag, demonstrated 94.7% clinical sensitivity, 98.8% specificity, along with 100% sensitivity and specificity for methicillin-resistant Staphylococcus aureus bacteremia. The conventional process of growing a culture—the medical laboratory’s gold standard—typically takes between one to three days to become positive and two more days to identify the bacteria and their antibiotic sensitivity patterns. Mobidiag’s Prove-it sepsis assay returns results in only 18 hours.

Canadian scientist steals specimens, caught by U.S. Customs agent at the border
Laboratories are invariably out of the public eye—until there is a problem. In Canada, The Canadian Press reported earlier this year that audits had uncovered serious flaws in the tracking and accountability of dangerous pathogen specimens at federal laboratories. In response, the Public Health Agency of Canada (PHAC) called for increased security measures governing bio-safety at government laboratories.
These problems were identified at the nation’s National Microbiology Laboratory, located in Winnipeg. Earlier in the year, this lab played the lead role in testing swine flu (Novel A/H1N1) samples and mapped the progression of this flu strain from Mexico to Canada. Other labs visited and found lacking in full protection of pathogen specimens included the Laboratory for Foodborne Zoonoses in Guelph, Ontario, and federal satellite labs in Alberta and Quebec.
