Bad 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 ...

From Yemen to Mayotte, the spread of a highly drug-resistant cholera strain
Scientists have revealed the spread of a highly drug-resistant cholera strain. The strain is resistant to ten antibiotics – including azithromycin and ciprofloxacin, two of the three recommended for treating cholera – and was identified for the first time in Yemen in 2018-2019.
