6.3: Isolation, Culture, and Identification of Viruses
2024年4月21日 · Viral cultivation requires the presence of some form of host cell (whole organism, embryo, or cell culture). Viruses can be isolated from samples by filtration. Viral filtrate is a rich source of released virions. Bacteriophages are detected by presence of clear plaques on bacterial lawn.
Virology Culture Guide - ATCC
The virus life-cycle can be divided into three major steps: attachment, assembly, and release. Generally, infection is established when the virus binds to a specific cellular receptor and enters the host cell. Upon cellular entry, host proteins are recruited to assist with viral replication.
Summary. Virus fundamentals. − Propagation strategies depend on how a virus infects and is released from host cells − Host cells must be susceptible and permissive for viral propagation to be successful − Virus propagation can be broken down into 3 …
