...cessary for prevention. However, recent threats of bioterrorism after 9/11 have spurred the development of a new safer vaccine that can be given to immune-compromised individuals....

Smallpox outbreak: How long would it take for vaccines to protect people? Would it work?

...because of the recent concern about biowarfare and bioterrorism throughout the world, the U.S. government is making efforts to improve its ability to protect its citizens in the event of a bioterrorist attack involving the smallpox virus (Variola major virus). This study at Saint Louis University will look at ...

Discovery could lead to better control of hemorrhagic fever viruses

... government interest because of their potential as bioterrorism agents. All four are classified as NIAID Category A Priority Pathogens and must be handled in Biosafety Level 4 containment facilities. The researchers, led by Hyeryun Choe, PhD, of Children's Hospital Boston's Pulmonary Division, and Michael Farz...

Scientists create dual-modality microbeads to improve identification of disease biomarkers

...low virus concentration or a sample of water for a bioterrorism agent has always been a time-consuming and difficult process. Researchers at the Georgia Institute of Technology and Emory University have developed an easier and faster method to detect these types of target molecules in liquid samples using highly ...

Silver bullet: UGA researchers use laser, nanotechnology to rapidly detect viruses

...etecting a naturally occurring disease outbreak or bioterrorism attack. "It saves days to weeks," said lead author Ralph Tripp, Georgia Research Alliance Eminent Scholar in Vaccine Development at the UGA College of Veterinary Medicine. "You could actually apply it to a person walking off a plane and know if th...

Nanotech tools yield DNA transcription breakthrough

... addition, bacterial pathogens that may be used in bioterrorism can be engineered, and, in the former Soviet Union, were intentionally engineered to be resistant to current antibiotics. Ebright explained that his laboratory at Rutgers' Waksman Institute of Microbiology has two parts: One part seeks a fundament...

Study finds the air rich with bacteria

...s that will help a Department of Homeland Security bioterrorism surveillance program differentiate between normal and suspicious fluctuations in airborne pathogens. It will also help scientists establish a baseline of airborne microbes, which they can use to track how climate change affects bacterial populations....

Vaccine combined with short-term postexposure antibiotics protects monkeys from inhalational anthrax

...plications for public health management of anthrax bioterrorism events. Anthrax is caused by the spore-forming bacterium Bacillus anthracis, and causes three types of disease--cutaneous, gastrointestinal, and inhalational--depending upon the route of exposure. Inhalational anthrax--the type likely to occur foll...

Ancient ants arose 140-168 million years ago

...tool for rapidly detecting norovirus--a category B bioterrorism agent--and other viral public health threats. The study is published in the April 2006 edition of Applied and Environmental Microbiology. In simplified terms, mass spectrometry is essentially a scale for weighing molecules. A laser turns a sample in...

Scientists reveal how deadly toxin hijacks cells

...linum neurotoxins are among the six most dangerous bioterrorism threats," adds lead author Min Dong, a UW-Madison postdoctoral researcher in the department of physiology. "Knowing the protein receptor for [botulinum toxins] can pave the way for developing anti-toxin reagents which may block the entry of toxins in...

Gene patterns in white blood cells quickly diagnose disease

Driver of anthrax toxicity could lead to late-stage therapy

...hich has been the focus of biological interest and bioterrorism concern. The virulence of the bacteria depends on separate complexes formed by interaction of a carrier protein, protective antigen, with lethal and edema factors responsible for the toxic effects and swelling that impairs the host's immune response....

Portable cocaine sensor developed at UC Santa Barbara

...cations of the sensor are far-reaching and include bioterrorism detection and important medical uses. The high school students made their own sensors and collected data shown in a graph in the scientific article they co-authored describing the work. In the article, published in the Feb. 18 issue of the Journal o...

UCSD study finds anthrax toxins also harmful to fruit flies

...subject because of its possible use as a weapon of bioterrorism and remains a health threat in third world countries," Guichard said. "Anthrax infections can be cured by antibiotics when detected early. But after a certain point, the toxins released in the bloodstream can kill the patient even after antibiotic tr...

War on terror meets war on cancer

...re complicated to determine where bacteria used in bioterrorism were grown. That isn't true of anthrax, which is spread by spores that are almost dormant. But for live bioweapons spread through the air in an aerosol mist ?bacteria that cause plague, tularemia or Q fever, for example ?the difference in isotope con...

New vaccine platform may fight infections with causes from influenza to bioterrorism

...ndicate it may be feasible to develop vaccines for bioterrorism agents and transplant patients, as well as high-risk individuals who have defective CD4+ T-cell function," Dr. Kolls said. "We are excited about the results because they indicate that we can engineer a vaccine to create a new protection for those who...

Anthrax stops body from fighting back, study shows

...es. The need to find new ways to treat victims of bioterrorism has increased since the Sept. 11, 2001, terrorist attacks and the anthrax attacks that killed five people exposed to inhalation anthrax through the mail. The UF findings could lead to treatments that block anthrax from paralyzing the much-needed neut...
