Research shows how gut microbes affect stomach flu

A new study shows that gut microbes can modulate the severity of norovirus infection (the stomach flu, or the winter vomiting bug), based on the gut location first affected. Published in the journal Nature Microbiology on November 25, 2019, the study indicates new possibilities to treat norovirus infection.

Discovery in C. difficile biology opens new window to developing treatments for dangerous infections

A process called sporulation that helps the dangerous bacterium Clostridium difficile (C. difficile) to survive inhospitable conditions and spread is regulated by epigenetics, factors that affect gene expression beyond the DNA genetic code, researchers at the Icahn School of Medicine at Mount Sinai report.

Discovery enables strategies to be developed for preventing malaria transmission

The bacteria that form the gut microbiota influence important processes of the human body, such as digestion, nutrient absorption, and defense against pathogens. The same type of relationship is present in most animals, including in the Anhopheles darlingi mosquito, the main vector of malaria in Brazil.
