Isolation of Swine influenza virus in cell cultures and embryonated chicken eggs.

Abstract
Influenza virus isolation is a procedure to obtain a live and infectious virus that can be used for antigenic characterization, pathogenesis investigation, and vaccine production. Embryonated chicken egg inoculation is traditionally considered the "gold standard" method for influenza virus isolation and propagation. However, many primary cells and continuous cell lines have also been examined or developed for influenza virus isolation and replication. Specifically, swine influenza virus (SIV) isolation and propagation have been attempted and compared in embryonated chicken eggs, some primary porcine cells, and a number of continuous cell lines. Currently Madin-Darby canine kidney (MDCK) cells remain the most commonly used cell line for isolation, propagation, and titration of SIV. Virus isolation in embryonated chicken eggs or in different cell lines offers alternative approaches when SIV isolation in MDCK cells is unsuccessful. Nasal swabs, lung tissues, and oral fluids are three major specimen types for SIV isolation. In this chapter, we describe the procedures of sample processing, SIV isolation in MDCK cells and in embryonated chicken eggs, as well as methods used for confirming the virus isolation results.
