Phages work together to suppress CRISPR bacterial immunity

CRISPR, or clustered regularly interspaced short palindromic repeats, are an essential part of bacterial immunity designed to defend against foreign DNA. In bacteria, CRISPR acts just like it does in human cells as a pair ...

Technique may improve lung delivery of bacteria-killing phage

A new delivery system for bacteriophages—viruses that selectively attack harmful bacteria—could help give doctors a new way to battle lung infections that threaten older patients and people with cystic fibrosis.

CRISPR-Cas9 may be a double-edged sword for bacteria

A team of researchers with the Catholic University of America has found evidence that suggests a defense mechanism used by bacteria to ward off phage attacks might also be benefiting the phages. In their paper published on ...

Workbench for virus design

ETH researchers have developed a technology platform that allows them to systematically modify and customise bacteriophages. This technology is a step towards making phage therapies a powerful tool for combating dangerous ...

New 'sugar-glass' film uses viruses to kill harmful bacteria in food

With antibiotic resistance on the rise, bacterial contamination of food is becoming more problematic. Now in a study appearing in ACS Biomaterials Science & Engineering, scientists report that they have developed an antibacterial ...

Determining the 3-D structure of phages at atomic resolution

Phages have become a focus of research in the battle against antibiotic resistance. These bacteria-eating viruses have already proven effective in experiments against multidrug-resistant bacteria. However, the atomic structure ...

Bacteriophages, natural drugs to combat superbugs

Viruses that specifically kill bacteria, called bacteriophages, might one day help solve the growing problem of bacterial infections that are resistant to antibiotic treatment. Researchers at Baylor College of Medicine and ...
