Antibiotics

Even at high concentrations, antibiotics won't kill all bacteria. There are always a few survivors, even in a bacterial population that is genetically identical. Scientists at the KU Leuven (Belgium) and the University of Groningen (the Netherlands) discovered that these survivors share a common feature: they accumulate acid in their…

The evidence is in: Less is more when it comes to treating uncomplicated community-acquired pneumonia (CAP) in young children. Five days of antibiotic therapy resulted in a superior clinical response compared to 10 days of treatment and had the added benefit of a lower risk of inducing antibiotic resistance, according…

Rice University bioscientists have developed a microfluidic platform for high-throughput studies of how bacteria evolve antibiotic resistance. One syringe of a solution containing bacteria or an antibiotic can provide millions of microspheres for analysis.

Antibiotics were administered to most newborns who had blood cultures drawn, even those with low risk for early-onset sepsis (EOS), according to a retrospective cohort study. Among more than 7,500 newborns who had cultures drawn at two Philadelphia perinatal units, 80.4% of those at low risk for developing EOS were…

Lucintel Forecasts Fermentation Market to Grow at a CAGR of 7%-8% According to the recent study the fermentation market is projected to grow at a CAGR of 7%-8% from 2020 to 2025. Growth in this market is primarily driven by growing awareness on food preservation, increased demand for fermented ingredients…

Scientists have pinpointed a gene that helps deadly E. coli bacteria evade antibiotics, potentially leading to better treatments for millions of people worldwide. The University of Queensland-led study found a particular form of the bacteria -- E. coli ST131 -- had a previously unnoticed gene that made it highly resistant…

The findings are not a reason to fear hedgehogs, say the researchers. Credit: Pia B. Hansen Scientists have found evidence that a type of the antibiotic resistant superbug MRSA arose in nature long before the use of antibiotics in humans and livestock, which has traditionally been blamed for its emergence.…

NewsUKResearchers are using computers to redesign existing antibiotics.(PA) (PA Wire) Scientists have made a “giant leap” using supercomputers to combat the greatest threat to human health posed by antibiotic resistance. Each year about 700,000 people are estimated to die because of antibiotic resistant bacteria, and that number is expected to…

Expression of the enzyme diguanylate cyclase (DGC2884, in green) by a bacteria called Pantoea sp. YR343 on tree roots when forming biofilms and colonizing those roots. Arrows indicate locations of bacterial colonization. Credit: Oak Ridge National Laboratory Some microbes can form thin films called biofilms. These biofilms give them an…

New research has moved a step closer to harnessing viruses to fight bacterial infection, reducing the threat of antibiotic resistance. A growing number of infections, including pneumonia, tuberculosis, gonorrhoea, and salmonellosis, are developing antibiotic resistance, which means they becoming harder to treat, resulting in higher death rates, longer hospital stays…
