...a may evade the immune system’s defences and dodge antibiotics by climbing into our cells and then lying low to avoid detection. New research in the online open access journal BMC Genomics shows how S. aureus makes itself at home in human lung cells for up to two weeks. A team of 12 researchers from University ...

Researchers discover 'acquired' DNA key to certain bacterial infection

... CDC also notes that the bacterium’s resistance to antibiotics – already a problem – may be increasing. In contrast, the incidence of lung infection in patients with chronic lung diseases and cystic fibrosis is increasing. Understanding the mechanism by how M. avium penetrates the macrophage and infects human...

Then, C. difficile can cause symptoms ranging from diarrhea to life-threatening inflammations of the colon. In 2002 a new, more virulent strain began appearing in hospitals in the United States and Canada. Recently, t...

This led to their first study, funded by Central Manchester and Manchester Children's University Hospitals NHS Trust (CMMC) Chairman's Prize Award. They treated 13 patien...

Researchers develop way to calculate speed of bacterial sex

By developing a real-life model of bacterial gene transfer, UC-Davis researchers hoped to gain insight into the rates of bacterial adaptation in the environment. They report ...

Cow protein aids in treatment of gastrointestinal disorder

However, not all corals are able to produce such defenses under thermal stress. "Some corals show unusual resilience to the double threat [of pathogens and warming seas], and we sho...

Natural antibiotics yield secrets to atom-level imaging technique

... to explore the germ-killing properties of natural antibiotics called antimicrobial peptides (AMPs), which are produced by virtually all animals, from insects to frogs to humans. AMPs are the immune system's early line of defense, battling microbes at the first places they try to penetrate: skin, mucous membrane...
