New method offers insights into mechanisms of staphylococcal pathogenesis

Nearly one in three people globally unknowingly carries Golden staph, or Staphylococcus aureus, in their nose or on their skin. While the bacterium is harmless to most, it can lead to serious infection and even death if it enters the bloodstream through a cut, surgical wound or catheter.

Mapping the evolutionary timeline and population distribution of E. coli’s protective outer capsule

In a new study, published today (15 June) in Nature Communications, a multi-centre team led by the Wellcome Sanger Institute, the University of Oslo, Imperial College London and UCL, has mapped for the first time the evolutionary timeline and population distribution of Escherichia coli’s protective outer capsule, which is responsible for the bacterium’s virulence.

New method of insulin delivery lowers the risk of hypoglycemia compared to current diabetes treatments

Insulin production has, for the last 50 or so years, come with some risks to the patient. Even so, the medication is lifesaving for the estimated 537 million adults living with diabetes worldwide, with that number expected to grow.

Scientists identify major mechanism behind the transition between chronic and acute bacterial infections

People with weakened immune systems are at constant risk of infection. Pseudomonas aeruginosa, a common environmental bacterium, can colonize different body parts, such as the lungs, leading to persistent, chronic infections that can last a lifetime – a common occurrence in people with cystic fibrosis.

Study finds altered gut bacteria in people with early signs of Alzheimer's disease

People in the earliest stage of Alzheimer's disease - after brain changes have begun but before cognitive symptoms become apparent - harbor an assortment of bacteria in their intestines that differs from the gut bacteria of healthy people, according to a study by researchers at Washington University School of Medicine in St. Louis.

Vaginal seeding engrafts maternal bacteria in the bodies of cesarean section born neonates

Newborns delivered by cesarean section who are swabbed with the vaginal fluid of their mothers after birth have beneficial bacteria restored to their skin surface and stools, according to a new study.
