NewsThese bacteria perform a trick that could keep plants healthy
Researchers have shown that some types of soil bacteria can influence a plant’s balance of growth and defense. The bacteria produce an enzyme that can lower a plant’s immune activity and allow its roots to grow longer than they would otherwise.

NewsAfter lockdown, immune system reacts more strongly to viruses and bacteria
The lockdowns during the COVID-19 pandemic had a significant impact on people’s immune response to microorganisms. During the lockdown, inflammation level in the body was low, but afterwards, the immune system reacted more intensely to viruses and bacteria.

NewsBad bacteria can trigger painful gut contractions; new research shows how
After a meal of questionable seafood or a few sips of contaminated water, bad bacteria can send your digestive tract into overdrive. Your intestines spasm and contract, efficiently expelling everything in the gut. Source: Parthasarathy Lab and Guillemin Lab Immune cells (magenta) and cells expressing a reporter of ...

NewsScientists find a vulnerability in antibiotic resistance mechanism
Superbugs, bacteria that are immune to multiple antibiotics, pose a great challenge to modern medicine. Researchers from the B CUBE - Center for Molecular Bioengineering at TUD Dresden University of Technology and Institut Pasteur in Paris identified a weakness in the bacterial machinery that drives antibiotic resistance adaptation. Their findings, ...

NewsStaphylococcus aureus thwarts vaccines by turning on a protein that halts immune response
Approximately 30 clinical trials to date have failed to result in an effective human vaccine for Staphylococcus aureus but researchers have now identified a key reason for these failures, indicating that it may be possible to modify the vaccines to work in humans.
