Amyloid Precursor Keeps Bacteria From Building Biofilm Defences

A protein the human body produces naturally could counter the problem of bacterial build-up on medical implants causing infection, according to a new study from University of Michigan researchers. Artificial hip implants, knee implants, and catheters are all susceptible to infections. Bacteria that flow through the blood system can collect on these foreign surfaces and […]

The Unexhausted Potential Of E. Coli

In 1884, the German microbiologist and pediatrician Theodor Escherich began a study of infant gut microbes and their role in digestion and disease. During this study, he discovered a fast-growing bacterium that he called Bacterium coli commune, but which is now known as the biological rock star that is Escherichia coli (Escherich, 1988; Shulman et […]

Biofilm Bacteria Control Distant Cells Using Long-Range Electrical Signals

Bacteria living in diverse communities called biofilms create what are basically electronic advertisements, by sending long-range electrical signals to other bacterial species that can lead to the recruitment of new members to their biofilm community, new research reveals. The study comes from biologists at UC San Diego who recently found that bacteria resolve social conflicts […]

Oxygen Triggers Toxin Antitoxin System For Antibiotic Attacks

Adaptation to antibiotics is not the only cause of bacterial resistance. Sometimes the bacteria just go dormant. Now, researchers looking at compounds that attack bacteria’s ability to go dormant have found the first oxygen-sensitive toxin antitoxin system. Thomas K. Wood, professor of chemical engineering and holder of the Biotechnology Endowed Chair, Penn State, said: “Antibiotics […]
