Researchers at Indiana University School of Medicine have discovered how toxoplasma gondii, a single-celled parasite, maintains a steady supply of nutrients while replicating inside of its host cell: it calls for delivery.
Considering the ever-growing percentage of bacteria that are resistant to antibiotics, interest in medical use of plasma is increasing. In collaboration with colleagues from Kiel, researchers at Ruhr-Universität Bochum (RUB) investigated if bacteria may become impervious to plasmas, too. They identified 87 genes of the bacterium Escherichia coli, which potentially protect against effective components of plasma. 'These genes provide insights into the antibacterial mechanisms of plasmas,' says Marco Krewing.
A type of immune cell that contributes to inflammatory bowel disease exists in two forms, 'good' and 'bad.' A new Crick-led study in Immunity has characterized these distinct populations, which could help scientists to develop treatments targeting inflammation while preserving healthy gut function.
In the cities of developing nations, where unregulated antibiotic use is common and livestock jostle with people amid often unsanitary conditions, scientists have found a potentially troubling vector for the dissemination of anti-microbial resistant (AMR) bacteria -- wildlife.
A world-first study at James Cook University in Australia has found an alternative to antibiotics for treating bacterial infections in green sea turtles.
Researchers report visual evidence supporting the presence of bacteria within the microarchitecture of the placental tissue.
Scientists went looking for preserved collagen, the protein in bone and skin, in dinosaur fossils. They didn't find the protein, but they did find huge colonies of modern bacteria living inside the dinosaur bones.
An international group of leading microbiologists have issued a warning, saying that not including microbes -- the support system of the biosphere -- in the climate change equation will have major negative flow-on effects.
Human and mouse experiments show that an antibody in breastmilk is necessary to prevent necrotizing enterocolitis -- an often deadly bacterial disease of the intestine.
Virginia Tech biochemist Brandon Jutras has discovered the cellular component that contributes to Lyme arthritis, a debilitating and extremely painful condition that is the most common late stage symptom of Lyme disease.
