Researchers take step toward creating Salmonella vaccine

10-Feb-2025 - Salmonella might seem like a mild inconvenience to some, but for sensitive groups, it can prove dangerous or deadly. In fact, 26,500 people are hospitalized by the bacterial infection each year in the U.S., and 420 people die, according to the U.S. Centers for Disease Control and Prevention. In ...

What's that smell? New gut microbe produces smelly toxic gas but protects against pathogens

Taurine-degrading bacteria influence intestinal microbiome

21-Sep-2023 - An international team of scientists led by microbiologist Alexander Loy from the University of Vienna has discovered a new intestinal microbe that feeds exclusively on taurine and produces the foul-smelling gas hydrogen sulfide. The researchers have thus provided another building block in the ...

A sponge playing in defence

Bacteria are extremely resourceful when it comes to adapting to a given environment: A team of researchers has now discovered a new trick

09-Feb-2022 - Each year, at least 1.27 million people die from an infection with bacteria that are resistant to standard antibiotics, a study recently published in the journal The Lancet reveals. The authors fear that this number could rise to as many as ten million people by 2050. This makes the hunt for new ...

The discovery of ancient Salmonella

Oldest reconstructed bacterial genomes link agriculture and herding with emergence of new disease

25-Feb-2020 - Using Salmonella enterica genomes recovered from human skeletons as old as 6,500 years, an international team of researchers illustrates the evolution of a human pathogen and provides the first ancient DNA evidence in support of the hypothesis that the cultural transition from foraging to farming ...

Antimicrobial resistance is drastically rising

24-Sep-2019 - An international team of researchers led by ETH has shown that antimicrobial-resistant infections are rapidly increasing in animals in low and middle income countries. They produced the first global of resistance rates, and identified regions where interventions are urgently needed. The world is ...

Glow Reveals Dangerous Bacteria

Chemiluminescence probes for the rapid and sensitive detection of salmonella and listeria

04-Jul-2019 - Salmonella and listeria are among the most widely distributed and deadliest causes of foodborne infections. Their rapid and reliable detection on food and industrial food processing equipment is very important. In the journal Angewandte Chemie, scientists have introduced a new, ultrasensitive, ...

Machine learning to identify source of Salmonella

Quick identification of animal source key to stopping foodborne illness outbreaks

13-Feb-2019 - A team of scientists led by researchers at the University of Georgia Center for Food Safety in Griffin has developed a machine-learning approach that could lead to quicker identification of the animal source of certain Salmonella outbreaks. In the research, Xiangyu Deng and his colleagues used ...

Utilizing CRISPR for better antibiotics

Drug screening with Mobile-CRISPRi

15-Jan-2019 - A University of Wisconsin-Madison researcher and his collaborators at the University of California, San Francisco have repurposed the gene-editing tool CRISPR to study which genes are targeted by particular antibiotics, providing clues on how to improve existing antibiotics or develop new ...

Researchers discover Achilles' heel of bacteria

07-Aug-2017 - Salmonellae are particularly resistant to antibiotics since they possess not only one, but two membranes that protect them from harmful substances. This makes them members of the so-called Gram-negative bacteria. Since Salmonella infections are becoming increasingly difficult to treat with ...

Fighting the gram-negatives

Natural products inspire the design of molecular agents against drug-resistant bacterial strains

31-Oct-2016 - Many microorganisms produce secondary natural products, the potential antibiotic effects of which are extensively investigated. German scientists have now examined a class of quinone-like substances containing an additional epoxide functional group for their antibiotic activities. As they report, ...
