Genes that make bacteria resistant to last-resort antibiotics

Human neutrophil ingesting MRSA

Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have found several previously unknown genes that make bacteria resistant to last-resort antibiotics. The genes were found by searching large volumes of bacterial DNA and the results are published in the scientific journal Microbiome. The increasing number of …

Pest resistance to Bt proteins produced by biotech crops

Pest resistance

In 2016, farmers worldwide planted more than 240 million acres (98 million hectares) of genetically modified corn, cotton and soybeans that produce insect-killing proteins from the bacterium Bacillus thuringiensis, or Bt. These Bt proteins kill some voracious caterpillar and beetle pests, but are harmless to people and considered environmentally friendly. …

Klebsiella bacteria can cause life threatening infections

A team of US researchers has discovered that three different species of Klebsiella bacteria can cause life threatening infections in hospital patients and that all three share genes that confer resistance to the most commonly used antibiotics. The study, published this week in mSphere®, an open-access journal of the American Society for …

New data on antibiotic consumption and antibiotic resistance

The European Food Safety Authority, the European Medicines Agency and the European Centre for Disease Prevention and Control are concerned about the impact of use of antibiotics on the increase in antibiotic-resistant bacteria. The report presents new data on antibiotic consumption and antibiotic resistance and reflects improved surveillance across Europe. …

Treatments of drug-resistant bugs by using nanotechnology

Antibiotic resistance is a growing problem, especially among a type of bacteria that are classified as “Gram-negative.” These bacteria have two cell membranes, making it more difficult for drugs to penetrate and kill the cells. Researchers from MIT and other institutions are hoping to use nanotechnology to develop more targeted treatments …

Antibiotic resistance mechanisms on experimental farmland

Canadian researchers have generated both novel and existing antibiotic resistance mechanisms on experimental farmland, by exposing the soil to specific antibiotics. The research is published in Applied and Environmental Microbiology, a journal of the American Society for Microbiology. “Antimicrobial resistance is a global threat to human and animal health with …
