[Advances of Researches on Anti-phage Mechanisms of Host].

Phages also known as bacteria viruses, are recognized as the most abundant and diverse microbes. This diversity is adapting to the selective pressures such as the prevalence of the phage resistance mechanisms of bacteria. Phages invade and lyse bacterial through six steps (adsorption, injection, replication, transcription translation, assemble, release). Bacteria evolve to many anti-phage mechanisms to avoid phage infection and lysis. This paper focus on a variety of anti-phage mechanisms of bacteria.
