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.
Remote imaging can effectively detect a pathogen that endangers the Florida avocado industry – even before the trees show symptoms — University of Florida scientists say.
Deadly viruses responsible for Ebola hemorrhagic fever and other infectious diseases will be imported into Japan by a government laboratory to improve detection and preparedness.
If similar samplers are deployed at airport checkpoints or other high-risk crowded places, potential biological threats such as SARS and the H7N9 strain of bird flu could be detected in eight hours or less.
The developed VFI shows great potential as a point-of-care tool for detection of bio-threat agents in a variety of clinical and resource-restricted conditions.
The key to the device, which in rudimentary terms involves placing a small amount of food on a cassette containing desiccated hydrogel, is the elimination of the bacteria enrichment phase currently used in most testing techniques.
