Now, Johns Hopkins Medicine scientists say they have shed new light on how bacteria protect themselves from certain phage ...

Phages are viruses that attack bacteria by injecting their DNA, then usurping bacterial machinery to reproduce. Eventually, they make so many copies of themselves that the bacteria burst.

University of Toronto researchers have discovered nine new genes used by bacteria to protect themselves against ...

Bacteria steal DNA from silent viruses and use it like a memory bank. That memory helps them protect future generations.

In contrast, gram-positive bacteria typically use processed oligopeptides ... researchers identified a comparable communication system in temperate bacterial phages—viruses that enter either the lytic ...

Bacteriophages are viruses that infect bacteria. Some phages follow a lytic life cycle where they inject their DNA into the host cell and hijack its mechanisms to reproduce. When the number of ...

They performed density gradient centrifugation to separate phages from bacterial lysates and found that the bacteria that expressed Bil produced a higher density band in the gradient. When the ...

Researchers are investigating whether certain viruses known as bacteriophages, or phages, which specifically infect bacteria but not human cells, affect the development of type 1 diabetes in young ...
