The bacteriophage Siphovirus

Nanoclustering Scientific Illustration SIPHOVIRIDAE LIFE CYCLE Siphoviridae is a family of non-enveloped viruses that haye' an icosahedral head and a long, non-contractile, and flexible tait with short terminal fibres. Their natural hosts are bacteria and archaea, and there is currently a total of 783 species in this family. Siphoviruses enter host cells via adsorption, and use cytoplasmic viral replication, and exit host cells through lysis. The siphovirus illustration is based on the marine bacteriophage TW1 and findings from the following publication: Wang, Z., Hardies, S., Fokine, A., Klose, T., Jiang, W., Cho, B. and Rossmann, M., 2018.
