To trigger Crohn’s disease, pathogenic bacteria co-opt genetic susceptibility

Leave a Comment / Genetics / By

Changes in a single gene open the door for harmful gut bacteria to trigger the inflammation that leads to Crohn’s disease, according to a new study led by Weill Cornell Medicine and NewYork-Presbyterian researchers. These findings could one day help doctors better select targeted treatments for patients with this immune disorder. This particular host gene, …

Researchers from the Quadram Institute and the University of East Anglia have discovered how resistance has contributed to the emergence of dominant strains of Salmonella. In addition to antimicrobial resistance, bacteriophage resistance can give these insects a boost, at least in the short term. With the rise in antimicrobial resistance, the search for new ways …

Clinical implementation of continuous genomic surveillance to identify, track and interrupt the transmission of multidrug-resistant bacterial pathogens

Leave a Comment / Genetics / By

Hospital-acquired infections (HAIs) are generally associated with an increased risk of developing antimicrobial resistance (AMR). Globally, many patients are affected by HAIs, which has significantly increased the overall operational cost of the healthcare system. Although it is extremely important to identify pathogens with high transmission rates in hospital settings, the capacity of diagnostic laboratories is …

Hidden deep in a cave – Discovery of a unique new species of bacteria

Leave a Comment / Science / By

An image of an HS-3 plated colony, showing the characteristic transparent and iridescent appearance. 1 credit Japanese scientists have discovered a type of bacteria in a cave that exhibits multicellular behavior and a unique two-phase life cycle. The bacterium, HS-3, was isolated from a limestone cave wall that is periodically submerged by an underground river. …
