• Bacteria discovery could lead to antibiotics alternatives

    Researchers say findings of new research could lead to the development of new anti-infective drugs as alternatives to antibiotics whose overuse has led to resistance

  • Early detection of malaria saves lives

    The timely diagnosis of malaria maximizes the likelihood of successful, life-saving treatment; it also minimizes the chances that inappropriate therapy will be given, which would help combat the growing problem of drug resistant malaria

  • Rapid, low-cost, point-of-care flu detection demonstrated

    The novel H1N1 flu pandemic in 2009 underscored weaknesses in methods widely used to diagnose the flu, from frequent false negatives to long wait times for results; scientists demonstrate a prototype rapid, low-cost, accurate, point-of-care device that promises a better standard of care

  • Two RNA-based therapeutic candidates for Ebola, Marburg viruses

    Under a contract for up to $291 million from the U.S. Department of Defense, AVI BioPharma has initiated clinical studies for two RNA-based drugs for the treatment of Ebola and Marburg viruses

  • Solving antibiotic resistance in humans -- and premature bee death

    The stomachs of wild honey bees are full of healthy lactic acid bacteria that can fight bacterial infections in both bees and humans; the finding is a step toward solving the problems of both bee deaths and antibiotic resistance in humans

  • Rethinking the toilet model in developing countries

    More than 2.6 billion people around the world lack access to basic sanitation, and more than 40 percent of the world’s population lack access to even the simplest latrine; the lack of sanitation creates serious problems, including environmental pollution, unsafe surroundings, and increasing the outbreak of lethal epidemic diseases such as cholera; Swedish company offers a solution

  • The bioterrorism threat and laboratory security

    Leonard A. Cole, an expert on bioterrorism and on terror medicine who teaches at Rutgers University, investigates the security of U.S. high containment labs in light of the dramatic growth in the number of these labs, which handle dangerous pathogens, following 9/11 and the anthrax attacks

  • Origami-inspired paper sensor tests for malaria, HIV for less than 10 cents

    Chemists have developed a 3-D paper sensor that may be able to test for diseases such as malaria and HIV for less than ten cents a pop; such low-cost, point-of-care sensors could be useful in the developing world, where the resources often do not exist to pay for lab-based tests, and where, even if the money is available, the infrastructure often does not exist to transport biological samples to the lab

  • Public health expert: budget cuts will erode response capabilities

    Homeland Security NewsWire’s executive editor Eugene K. Chow recently got the opportunity to speak with Dr. John R. Finnegan, the dean of the University of Minnesota School of Public Health; in their interview, Dr. Finnegan discusses the devastating effects of proposed budget cuts on the U.S. public health system, why it was a wise decision to censor the release of H5N1 flu research; and the creation of a medical reserve corps at universities

  • New repellant frightens mosquitoes to death

    Anopheles gambiae mosquitoes carry and spread diseases, including malaria, the second most deadly transmitted disease in Africa; mosquitoes zero in on their next meal – human blood — using their keen sense of smell; a new repellent would bombard the mosquitoes with so many strong odors, it would scare them away from human odors

  • Drug-resistant MRSA in livestock now infects humans

    A novel form of MRSA, a methicillin-resistant Staphylococcus aureus called ST398, can now be found in pigs, turkeys, cattle, and other livestock and has been detected in 47 percent of meat samples in the United States; the figures illustrate a very close link between antibiotic use on the farm and potentially lethal human infections

  • Antibiotic alternative to overcome drug-resisting infections

    About 700 million people have symptomatic group A Streptococcus (GAS)  infections around the world each year, and the infection can be fatal; researchers have found a potential alternative to conventional antibiotics that could fight infection with a reduced risk of antibiotic resistance

  • Using ozone to kill prions dead

    Prions are among the worst infectious-disease agents; these proteins are resistant to a wide variety of extreme disinfectant procedures; they have been identified as the culprits behind mad cow disease and chronic wasting disease in animals and humans, and are also implicated in Creutzfeldt-Jakob disease and other prion-related disorders

  • Scientists offer new information for fighting flu

    Influenza is the world’s leading cause of morbidity and mortality; seasonal viruses affect up to 15 percent of the human population and cause severe illness in five million people a year; in the United States, financial losses caused by seasonal influenza are estimated to exceed $87 billion annually

  • Stealthy leprosy pathogen evades immune response

    Leprosy, one of the world’s oldest known diseases, is a chronic infectious disease that affects the skin, the peripheral nerves, the upper respiratory tract, and the eyes and can lead to disfigurement of the hands, face, and feet; scientists’ findings point to new treatment pathways for leprosy – and other infectious diseases
