[Answer] bacteriophages

Answer: viruses of bacteria
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. They are extremely diverse in size morphology and genomic organization [1][2][3]. However all consist of a nucleic acid genome encased in a shell of phage-encoded capsid proteins which …
Bacteriophages are among the most common and diverse entities in the biosphere. Bacteriophages are ubiquitous viruses found wherever bacteria exist. It is estimated there are more than 10 31 bacteriophages on the planet more than every other organism on Earth including bacteria combined.
A bacteriophage is a virus that infects bacteria. A bacteriophage or phage for short is a virus that infects bacteria. Like other types of viruses bacteriophages vary a lot in their shape and genetic material. Phage genomes can consist of either DNA or RNA and can contain as few as four genes or as many as several hundred.
Bacteriophages are used to treat a bacterial infection which is known as phage therapy. Phages have several characteristics including their effectiveness in killing their target bacteria their specificity adaptability natural residence in the environment and the fact that they are self-replicating and self-limiting ( Jassim et al. 2016 ).

“ Bacteriophages are the viruses that infect bacteria.” What is Bacteriophage? A bacteriophage is a virus that infects a bacterial cell and reproduces inside it. They vary a lot in their shape and genetic material. A bacteriophage may contain DNA or RNA. The genes range from four to several thousand.
