Zone of inhibition produced by Streptomyces sp myrophorea on a lawn of MRSA. The bacteria is the brown spot, and the lighter colour around the spot shows that it is inhibiting the spread of the MRSA which is surrounding it.

Bacteria found in ancient Irish soil halts growth of superbugs

Science Notes: The discovery offers new hope for tackling antibiotic resistance

By
Researchers analyzing soil from Ireland long thought to have medicinal properties have discovered that it contains a previously unknown strain of bacteria effective against four of the top six superbugs that are resistant to antibiotics, including MRSA. Antibiotic resistant superbugs could kill up to 1.3 million people in Europe by 2050, according to recent research. […] Read more

Antibiotic combinations surprisingly effective

Science Notes: Research findings could be a major step in fighting common infections increasingly resistant to antibiotics

By
Scientists have traditionally believed that combining more than two drugs to fight harmful bacteria would yield diminishing returns. The prevailing theory is that the incremental benefits of combining three or more drugs would be too small to matter, or that the interactions among the drugs would cause their benefits to cancel one another out. Now, […] Read more

Understanding soil through its microbiome

Science Notes: More physical and social activity may partially explain the findings

By
Soil is full of life, essential for nutrient cycling and carbon storage. To better understand how it functions, an international research team led by EMBL and the University of Tartu (Estonia) conducted the first global study of bacteria and fungi in soil. Their results show that bacteria and fungi are in constant competition for nutrients […] Read more

Bovine TB probe turns up more TB-positive cattle

By
Federal inspectors have confirmed a southeastern Alberta cow found with bovine tuberculosis in September was not just a one-off. The Canadian Food Inspection Agency on Friday reported five more cattle from the initial cow’s index herd in southeastern Alberta are confirmed to have been infected with Mycobacterium tuberculosis bacteria — presumed to be to be […] Read more

Scientists create ‘genetic firewall’ for new forms of life

By
New York | Reuters — A year after creating organisms that use a genetic code different from every other living thing, two teams of scientists have achieved another “synthetic biology” milestone: They created bacteria that cannot survive without a specific manmade chemical, potentially overcoming a major obstacle to wider use of genetically modified organisms (GMOs).
