[Progress in establishment and application of feline calicivirus reverse genetics operating system]

Feline calicivirus (FCV) is an important and highly prevalent pathogen of cats that causes feline respiratory disease. The reverse genetic systems for FCV have been established in national and international laboratories since 1995. This technique has been used widely in FCV basic research and good progress has consequently been made to determine the relationship between viral genome structures and the function of their proteins, the expression of foreign proteins, virus-host interactions, and viral pathogenic mechanisms. In this article,we review the state of progress with regards to the establishment and application of the FCV reverse genetic operating system,which will provide a useful reference tool for future related research.
