Bacterial Research; How depleting the gut microbiota protects from obesity ♦ Concerted action needed to control healthcare-related infection ♦ New technique could prevent dangerous biofilms on catheters

New information about bacterial enzymes to help scientists develop more effective antibiotics, cancer drugs New research now allows researchers to manipulate nature's biosynthetic machinery to produce more effective antibiotics and cancer-fighting drugs.
How depleting the gut microbiota protects from obesity By studying mice without microbiota, scientists were able to demonstrate how the absence of microbiota has a remarkable effect against obesity. Indeed, it triggers a surprising metabolic mechanism: white fat cells -- which in excess cause obesity and insulin resistance -- are transformed into cells similar to brown fat (they are called 'beige fat'), that protects the body against excess weight and its damaging consequences.
Responding to C. diff: Concerted action needed to control healthcare-related infection Appropriate use of antibiotics is a critical step toward controlling the ongoing epidemic of health care-related Clostridium difficile infection, according to a special article from experts
New technique could prevent dangerous biofilms on catheters Biofilms frequently coat the surfaces of catheters, and of various medical implants and prostheses, where they can cause life-threatening infections. New research shows that coating implants with a certain 'activator' can prevent Staphylococcus aureus, the leading cause of hospital-acquired infections, from forming biofilms
