Anthrax is an acute infectious disease caused by the spore-forming bacterium Bacillus anthracis. Anthrax most commonly occurs in wild and domestic lower vertebrates (cattle, sheep, goats, camels, antelopes, and other herbivores), but it can also occur in humans when they are exposed to infected animals or tissue from infected animals.
Anthrax is most common in agricultural regions where it occurs in animals. These include South and Central America, Southern and Eastern Europe, Asia, Africa, the Caribbean, and the Middle East. When anthrax affects humans, it is usually due to an occupational exposure to infected animals or their products. Workers who are exposed to dead animals and animal products from other countries where anthrax is more common may become infected with B. anthracis (industrial anthrax). Anthrax outbreaks occur in the United States on an annual basis in livestock and wild game animals such as deer.
Anthrax infection can occur in three forms: cutaneous (skin), inhalation, and gastrointestinal. B. anthracis spores can live in the soil for many years, and humans can become infected with anthrax by handling products from infected animals or by inhaling anthrax spores from contaminated animal products. Anthrax can also be spread by eating undercooked meat from infected animals. It is rare to find infected animals in the United States.
In a new twist to the 2001 anthrax attacks in the U.S., the Federal Bureau of Investigation is searching 2 homes in new York and New Jersey which may be related to the attacks.
Authors of a research letter in this week’s issue of THE LANCET outline progress in the ability to rapidly detect anthrax inhalation in the event of bioterrorist attacks.
A new book published by the Pan American Health Organization (PAHO) predicts that the 21st century will become the "century of vaccines" thanks to rapid developments in the field of immunization.
Researchers at the U.S. Department of Energy's Argonne National Laboratory and the University of Chicago have determined the crystal structure of sortase B, an enzyme found in the bacteria that cause staph and anthrax. While an antibiotic is probably five to seven years away, the structure could provide the first clue in developing a treatment for the infections.
Emerging infectious diseases, which have shaped the course of humanity and caused incalculable suffering and death, will continue to confront society in unpredictable ways as long as humans and microbes co-exist
A team of researchers led by The Burnham Institute’s Robert C. Liddington has determined the crystal structure of the binding complex between anthrax toxin and one of its host receptors.
Scientists have determined a three-dimensional (3-D) molecular image of how anthrax toxin enters human cells, giving scientists more potential targets for blocking the toxin, the lethal part of anthrax bacteria.
William Winkenwerder, Jr., MD, assistant secretary of defense for health affairs has announced the extension of the vaccination programs against anthrax to include U.S. forces in the Pacific Commands including Korea.
The phase II trial will evaluate the safety and immunogenic response of a new recombinant anthrax vaccine, known as rPA102. The vaccine candidate consists of recombinant Protective Antigen (rPA), a synthetic protein that induces antibodies designed to prevent illness by neutralizing anthrax toxins, and aluminum hydroxide to enhance the immune response.
Dr. Fraser discusses, for the first time, the significance of the discovery of anthrax toxin genes in a naturally occurring microbe other than Bacillus anthracis, the bacterium that causes anthrax.
La Trobe University scientists are using their own unique peptide 'library' containing a thousand million molecular sequences in a project aimed at eliminating anthrax as a potential weapon for terrorists.
Once a deadly disease associated with animals, anthrax is now used as a bioterrorist weapon. While infection can be controlled with antibiotics, in a bioterrorism attack people will not know they have been infected until symptoms develop, at which stage drugs are useless.
The M-SERIES product line has multiple applications and currently serves the biodefense, life science research and food testing markets.
Fears that dead bodies will spread infection and disease following natural disasters are largely baseless, and simply serve to prolong the suffering of surviving friends and family members, according a scientific article published today.
Their method uses "Cellular Analysis and Notification of Antigen Risks and Yields" (CANARY) cells, which are immune-system cells engineered to contain a fluorescent protein naturally found in jellyfish. CANARY cells have the immune system's ability to detect specific disease-causing agents, lighting up when they recognize a pathogen.
University of Chicago scientists have identified a compound that halts the activity of a deadly toxin called anthrax lethal factor in laboratory tests. Nature Biotechnology will publish the findings online on May 16 and in the June issue of the journal's print edition.
Soon you may be wearing your computer, or elements of it, according to a team of researchers and designers at Arizona State University. The era of smart bodysuits is about to begin.
Equipment that can ‘see’ anthrax inside envelopes or explosives in luggage by recognising the distinctive shape of their molecules will be developed by researchers in the newly-built terahertz lab at Leeds, England.
A new device, nicknamed "the anthrax smoke detector,' which relies on technology developed by JPL and Caltech scientists, may serve as a first line of defense against acts of bioterrorism.
In 2001, bioterrorist activities involving the U.S. Postal Service infected 22 individuals with Bacillus anthracis (anthrax), according to background information in the article. Six survivors had inhalational anthrax and 11 cutaneous anthrax disease. Little is known about potential long-term health effects of bioterrorism-related anthrax infection.
