A biosafety cabinet (BSC)—also called a biological safety cabinet or microbiological safety cabinet—is an enclosed, ventilated laboratory workspace for safely working with materials contaminated with (or potentially contaminated with) pathogens requiring a defined biosafety level.
For instance, Andes orthohantavirus and MERS-CoV are both non-select agents that are often handled in BSL-4 because they cause severe and fatal disease in humans. Newly characterized viruses closely related to select agents and/or BSL-4 viruses (for example newly discovered henipaviruses or ebolaviruses ) are typically handled in BSL-4 even if ...
Tolerance to infection, or disease tolerance, is a mechanism that host organisms can use to fight parasites or pathogens that attack the host. Tolerance is not equivalent to resistance. Disease resistance is the host trait that prevents infection or reduces the number of pathogens and parasites within or on a host.
This new strain resulted from the recombination of genes between several parent viruses noted in poultry and wild birds in Asia. The H7 gene is most closely related to sequences found in samples from ducks in Zhejiang province in 2011.The N9 gene was closely related to isolated wild ducks in South Korea in 2011. Other genes resembled samples ...
Transmission-based precautions are infection-control precautions in health care, in addition to the so-called "standard precautions". They are the latest routine infection prevention and control practices applied for patients who are known or suspected to be infected or colonized with infectious agents, including certain epidemiologically important pathogens, which require additional control ...
WASHINGTON (Reuters) -The U.S. Supreme Court declined on Monday to decide whether federally mandated warnings on cigarette packs that graphically illustrate the health risks of smoking violate the ...
For example, a study among 15 people with Crohn’s disease or colitis found that the AIP diet resulted in less frequent bowel movements and improved stress. However, there was no control group in ...
Heart Health: This area is less studied, but growing evidence shows that vitamin D could protect against cardiovascular disease. When estrogen levels drop during menopause, women’s risk of heart ...
