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 ...

Detecting bacteria in space

24-May-2019

Scientists at Université de Montréal and McGill University have pioneered and tested a new genomic methodology which reveals a complex bacterial ecosystem at work on the International Space Station. Their study is published today in Environmental Microbiology. Until now, relatively little was ...

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 ...

Fighting deadly drug resistant bacteria in intestines with new antibiotic

22-Jan-2019

A new antibiotic developed by a Flinders University researcher is being heralded as a breakthrough in the war against a drug resistant superbug. Bacteria are winning the fight against antibiotics as they evolve to fight off traditional treatments, threatening decades of advancements in modern ...

Candida albicans exploits lack of oxygen to cause disease

18-Jan-2019

Scientists from Umeå university have shown how the yeast Candida albicans can modulate and adapt to low oxygen levels in different body niches to cause infection and to harm the host. Studying adaption to hypoxic or anoxic niches is particularly fruitful, since it helps us to understand the ...

Pathogens may evade immune response with metal-free enzyme required for DNA replication

23-Oct-2018

Some bacterial pathogens, including those that cause strep throat and pneumonia, are able to create the components necessary to replicate their DNA without the usually required metal ions. This process may allow infectious bacteria to replicate even when the host's immune system sequesters iron ...

A novel antibiotic from weeds

30-Jul-2018

Researchers working on an SNSF project have discovered novel, antibiotically active chemical substances in a previously rarely explored site: the leaf of a common field weed. The just published findings show that this microcosm contains many still unknown natural products that could lead to new ...

Malaria-causing parasite manipulates liver cells to survive

24-May-2018

When the malaria-causing Plasmodium parasite first slips into the human bloodstream, injected by the bite of an infected mosquito, it does not immediately target red blood cells. Instead, it seeks refuge inside the liver and rapidly reproduces, copying itself as many as 30,000 times in the span ...

Findings discuss how Staphylococcus can colonize our noses but not cause infection

27-Apr-2018

According to the U.S. Centers for Disease Control and Prevention, about one in three humans carries Staphylococcus aureus, or "staph," in our noses, and 2 percent of us carry the dreaded methicillin-resistant (MRSA) strain that thwarts common antibiotics. So how is it that most of us never get ...

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 ...
