Viruses and pathogens

  • A natural food preservative kills food-borne bacteria

    Salmonella and E. coli account for more than half of all food recalls in the United States; salmonella contributes to an estimated 28 percent of more than 3,000 U.S. deaths related to foodborne illness each year; researchers have discovered and received a patent for a naturally occurring lantibiotic — a peptide produced by a harmless bacteria — that could be added to food to kill harmful bacteria like salmonella, E. coli, and listeria

  • Innovative biosensor for rapid virus field tests

    Relying on a novel DNA-based bio-chemo-physical conversion method, a new bio-detection device is able to detect harmful bacteria, such as E. coli, salmonella, and staphylococcus, on site, within thirty minutes; it can be adapted to cover such deadly viruses as SARS, H5N1 flu, and swine flu viruses; it can also be designed to monitor possible biological attack from anthrax, smallpox, cholera, and more

  • Gold nanoparticles help to diagnose flu in minutes

    Arriving at a rapid and accurate diagnosis is critical during flu outbreaks, but until now, physicians and public health officials have had to choose between a highly accurate yet time-consuming test or a rapid but error-prone test; University of Georgia researchers offer a solution

  • Five Joplin survivors die of mysterious fungal infection

    After being hit by a massive tornado that destroyed much of Joplin, Missouri, several residents suffered from a fungal infection that killed five people; following the 22 May twister that ravaged Joplin, many residents suffered from splinters, cuts, and other minor injuries that eventually resulted in a rare fungus infection

  • Research inspires robotics design for medicine, military

    A pathogen that attacks the small intestines of humans and animals is serving as the inspiration for developing robots that can fight disease and aid in military operations; ror 250 years, scientists have tried to understand how the microorganism is able to attach to a multitude of surfaces and swim in harsh environments — enabling it to infect many kinds of species while most parasites have specific hosts

  • Anthrax vaccine program demonstrates 36 month product stability

    Maryland-based PharmAthene has achieved an important program milestone in its recombinant protective antigen (rPA) anthrax vaccine program, and demonstrated thirty-six month stability of its rPA drug product candidate; the data suggest that the rPA product candidate is both highly stable and potent; stability has historically been a stumbling block for other recombinant anthrax vaccine programs

  • New way to attack Salmonella bacteria found

    Nitric oxide is naturally produced in the nose and the gut and other tissues in the body to ward off infection; new research underscores that nitric oxide’s antimicrobial actions are due to its interference with the metabolism, or energy production, of pathogens —p and that these antimicrobial characteristics may be harnessed to inhibit the growth of Salmonella

  • Natural enzyme can defend against terrorists' nerve agents

    Chemicals called organophosphates, found in common household insecticides, can be just as harmful to people as to insects; organophosphates could be released on an industrial scale, through an act of terror or accident, attacking the nervous system by inactivating an enzyme called acetylcholinesterase (AChE); scientists are devising drugs to treat and prevent the toxic effects of organophosphates and related chemicals

  • Satellites could predict next cholera outbreak

    With cholera making an unlikely resurgence, catching countries like Haiti and Pakistan by surprise, public health officials are exploring the potential for new technology to help stem the spread of future outbreaks; each year the disease affects three to five million people and claims more than 100,000 lives; researchers believe that satellite images of oceans could help forecast when a cholera outbreak is likely to strike

  • Nano detector spots deadly anthrax

    The average time of detection of an anthrax attack by current methods — the time required for DNA purification, combined with real-time polymerase chain reaction (PCR) analysis — is sixty minutes; a new, automatic, and portable detector takes just fifteen minutes to analyze a sample suspected of contamination with anthrax

  • New technology makes textiles permanently germ-free

    University of Georgia scientist develops a new technology that makes textiles permanently germ-free, targeting healthcare-associated infections; the new material effectively kills a wide spectrum of bacteria, yeasts, and molds that can cause disease, break down fabrics, create stains, and produce odors

  • Biolabs: the solution may be the problem

    Since the fall 2001 anthrax attacks, there has been a vast expansion of the U.S. bioterror research infrastructure; now, more than 11,000 scientists work on bioterrorism and agroterrorism research in seventeen major and many more smaller labs across the United States; billions of federal dollars are funding research on new vaccines and antibiotics to protect the population from anthrax, plague, tularemia, Ebola, and other lethal germs; what is the likelihood that there is another Bruce Ivins — perhaps more than one — among these thousands of researchers with access to the most lethal pathogens on Earth?

  • Promise of vaccine against deadly malaria parasite

    Every year, 10,000 pregnant women and up to 200,000 newborn babies are killed by the malaria parasite; the body’s immune system normally attacks any foreign body, but since our spleen constantly filters our blood and removes ruined or deform blood cells, the body’s natural defense does not need to check the blood; the malaria parasite exploits this fact by using its advanced arsenal of protein hooks to attach itself to the inner side of the blood vessel; researchers find a soltuon

  • How safe is Kansas bio lab from twisters?

    DHS officials say they are confident that the proposed bio-defense lab in Manhattan, Kansas, located in the heart of tornado alley, is capable of withstanding a direct hit from a powerful twister; engineers have hardened the $650 million National Bio and Agro-Defense Facility (NBAF) to withstand wind speeds of up to 230 miles per hour; but critics of the planned facility argue that the new standards are inadequate and that the facility must be further reinforced to ensure that in the event of a natural disaster the deadly pathogens and viruses stored there are not spread

  • Confusing mosquitoes to fight mosquito-borne disease

    Female mosquitoes are efficient carriers of deadly diseases such as malaria, dengue and yellow fever, resulting each year in several million deaths and hundreds of millions of cases; to find human hosts to bite and spread disease, these mosquitoes use exhaled carbon dioxide as a vital cue; a disruption of the vital carbon dioxide detection machinery of mosquitoes, which would help control the spread of diseases they transmit, has been a long sought-after goal; University of California-Riverside scientists find a way to do just that
