Genomic study of 412 anthrax strains provides new virulence clues

By analyzing genomic sequences from more than 400 strains of the bacterium that causes anthrax, researchers have provided the first evidence that the severity – technically known as virulence – of specific strains may ...

Addgene keeps flow of CRISPR plasmids fast and affordable

As a key global enabler of the revolutionary genome editing technology known as CRISPR, the nonprofit organization Addgene has made available more than 100,000 CRISPR plasmids (circular DNA fragments) to 3,400 laboratories ...

Bacteria can spread antibiotic resistance through soil

When most people think about bacterial antibiotic resistance, they think about it occurring in bacteria found in people or animals. But the environment surrounding us is a huge bacterial reservoir, and antibiotic resistance ...

DNA detectives crack the case on biothreat look-alikes

Biological "detectives" are tracking down biothreats such as the bacteria that causes tularemia ("rabbit fever"), but they constantly face the challenge of avoiding false positives. Sounding the alarm over a bioattack, only ...

Antibiotic resistance driven by intragenomic co-evolution

Scientists have discovered bacteria are able to "fine-tune" their resistance to antibiotics – raising the possibility of some superbugs being resistant to drugs which they have never even been in contact with.
