Bacteria can evolve rapidly to adapt to environmental change. When the “environment” is the immune response of an infected host, this evolution can turn harmless bacteria into life-threatening pathogens. A study published on December 12 in PLOS Pathogens provides insight into how this happens.
A protein in Salmonella inactivates mast cells — critical players in the body’s fight against bacteria and other pathogens — rendering them unable to protect against bacterial spread in the body, according to researchers at Duke Medicine and Duke-National University of Singapore (Duke-NUS).
Scientists have used a new method to map the response of every salmonella gene to conditions in the human body, providing new insight into how the bacteria triggers infection.
Scientists at the Stanford University School of Medicine have revealed that formerly overlooked sites deep inside the nose may be reservoirs for Staphylococcus aureus, a major bacterial cause of disease.
