Bacteria Acquire Resistance From Competitors

The frequent and sometimes careless use of antibiotics leads to an increasingly rapid spread of resistance. Hospitals are a particular hot spot for this. Patients not only introduce a wide variety of pathogens, which may already be resistant but also, due to the use of antibiotics to combat infections, hospitals

New Term for Role of Microbiota in Neurodegeneration Proposed

University of Louisville neurology professor Robert P. Friedland, M.D., and Matthew R. Chapman, Ph.D., professor at the University of Michigan, have proposed a new term to describe an interaction between gut microbiota and the brain in an article released today in PLOS Pathogens. Friedland and Chapman propose the term "mapranosis" for the

Designer Nanoparticles Destroy a Broad Array of Viruses

Now, an international group of researchers including UIC professor of chemistry Petr Kral, have designed new anti-viral nanoparticles that bind to a range of viruses, including herpes simplex virus, human papillomavirus, respiratory syncytial virus and Dengue and Lentiviruses. Unlike other broad-spectrum antivirals, which simply prevent viruses from infecting cells, the

Bacteria as Pacemaker for the Intestine

The triggers for the normal spontaneous contractions of the muscle tissue are so-called pacemaker cells of the nervous system. In a specific rhythm and without any external stimulation, they emit electrical impulses, that ultimately reach the smooth muscles of the intestinal wall, and cause them to contract. Although the impulses

In the Fight Against Viral Infection, Spelling Counts

Now, scientists have found that a key similarity between our genes and those of many viruses -- a way of spelling out the genetic code -- has likely allowed viruses to evade our cellular defenses. Paul Bieniasz, a Rockefeller professor and Howard Hughes Medical Institute Investigator who led the work,
