Japan’s National Institute of Infectious Diseases has begun tests on Ebola, Marburg, Lassa, Crimean-Congo, and South American hemorrhagic fever viruses in an attempt to make diagnoses more accurate and improve detection methods.
Researchers developed a technique using wave energy to reduce virus detection time by half for malaria, dengue fever, Middle East Respiratory Syndrome (MERS), and other infectious diseases. Minimizing hospital detection time from one hour to 25 minutes may help make a diagnosis in time to treat patients properly.
Detection tools will only continue to improve, cheapen, and miniaturize leading to widely distributed sequencers in homes, offices, the broader biosphere, and even within human bodies.
The new technique uses microneedle patches to collect DNA from plant tissues in one minute, rather than the hours needed for existing techniques.
Food processing plant surfaces must be cleaned regularly, and unlike swabs, artificially contaminated stickers were able to provide a record of contamination that took place over at least two weeks, despite washing, flushing with water, or wiping with the alcohol-based disinfectant
Bionanosensors may make it quicker and easier to detect harmful micro-organisms, but hurdles remain before they can enter the clinical realm.
The tool works for on-site detection of quarantine pathogens, such as Xylella fastidiosa, Ceratocystis platani and Phytophthora ramorum.
Early warning and rapid response are crucial to prevent or mitigate, the impact of biological invasions of plant pathogens,
Epidemiologists, veterinarians, and laboratory technicians from across Kyrgyzstan participated in a five-day specialized training to deepen their knowledge on existing diagnostic methods and procedures to prevent outbreaks caused by high-threat pathogens – such as anthrax, cholera, rabies, and brucellosis.
Los Alamos National Laboratory (LANL) researchers designed a Universal Bacterial Sensor—modeled after the human innate immune system—that mimics the biological recognition of all categories of bacterial pathogens. Requiring less than a drop of blood, it detects all pathogens without prior knowledge of what they might be, before symptom onset.
