Detailed explanation-1: -Bacteriophages, also known as phages, are viruses that infect and replicate only in bacterial cells. They are ubiquitous in the environment and are recognized as the most abundant biological agent on earth.

Detailed explanation-2: -More common, but less understood, are cases of viruses infecting bacteria known as bacteriophages, or phages.

Detailed explanation-3: -A bacteriophage is a type of virus that infects bacteria. In fact, the word “bacteriophage” literally means “bacteria eater, ” because bacteriophages destroy their host cells.

Detailed explanation-5: -The phage infection cycle seems to be simple but extremely efficient: a single phage injects its genome into a bacterial cell, switching the cells’ programme in its favour so the host cell will eventually die and release about 100 new phage particles.
