Abstract

Bacteriophages, also called phages, are viruses of bacteria. They are the most common and diverse biological entities on this planet. For metagenomic investigation, their diversity is also their biggest obstacle. The direct metagenomic sequence of environmental phage communities often leads to short genomic fragments limiting the investigation to a few individual aspects of phage biology and diversity.
The presented protocol for generating a host-associated metagenome reduces the phage diversity to a concise and accessible size. Metagenome sequencing often leads to complete genomes, and the availability of a suitable host system ensures further experimental investigation.
