Methodology can provide new insights into a variety of key topics in microbiology

17-Jan-2022 - Raman microspectroscopy is a fast and non-invasive technology to determine the chemical composition of living microorganisms in near real-time. Jürgen Popp, scientific director of the Leibniz Institute of Photonic Technology, together with an international team of expert scientists, describes the ...

Deep learning enables early detection and classification of live bacteria using holography

Development of an AI-powered smart imaging system for early-detection and classification of live bacteria in water samples

15-Jul-2020 - Waterborne diseases affect more than 2 billion people worldwide, causing substantial economic burden. For example, the treatment of waterborne diseases costs more than $2 billion annually in the United States alone, with 90 million cases recorded per year. Among waterborne pathogen-related ...

Biofilms - an invisible threat to food safety

Hotspots for biofilms

08-Jul-2020 - Biofilms are potential sources of contamination in the food industry. A recent study by the FFoQSI Competence Center at the Vetmeduni Vienna investigated where they hide and what bacteria can be found in them. Biofilms can cause additional costs in production and are a source of danger to ...

Structure of virus that infects bacteria in hot springs is revealed

06-Feb-2019 - Scientists have revealed the structure of a virus infecting bacteria that thrive in 160-degree hot springs in places like Yellowstone National Park in Wyoming. The discovery could lead to better targeted delivery of drugs into cells and new DNA sequencing technology, according to a study by ...

Study of COPD patients has created a 'looking glass' into genome of pathogen

21-Mar-2018 - Decades of work on chronic obstructive pulmonary disease (COPD) at the University at Buffalo and the Veterans Affairs Western New York Healthcare System have yielded extraordinary information about the pathogen that does the most harm to patients. The results provide the first insights into how ...

How Salmonella 'die' at low temperatures

08-Feb-2018 - The most economical way to kill bacteria that cause common food-borne illnesses -- mostly caused by Salmonella enterica -- is heat, but, the mechanisms that kill Salmonella at lower temperatures were not fully understood until now, according to a team of researchers. Bacteria can develop ways to ...

Immune cells that keep gut fungi under control

15-Jan-2018 - Immune cells that process food and bacterial antigens in the intestines control the intestinal population of fungi, according to a new study from Weill Cornell Medicine scientists. Defects in the fungus-fighting abilities of these cells may contribute to some cases of Crohn's disease and other ...

Illuminating the field of microscopy with nanoparticle 'buckyswitch'

14-Jul-2017 - Visualizing biological cells under a microscope was just made clearer, thanks to research conducted by graduate student Yifei Jiang and principal investigator Jason McNeill of Clemson University's department of chemistry. With the help of Rhonda Powell and Terri Bruce of Clemson's Light Imaging ...

Controlling bacteria's necessary evil

12-May-2017 - Microbes are everywhere -- on every surface, every object, every plant and animal. Yes, including on and inside you. True, some of them cause disease. Wait -- don't reach for the hand sanitizer just yet. Many of them are co-residents in our bodies, providing beneficial services in exchange for ...
