Comparative study of MDCK and CaCo-2 cell lines for influenza virus isolation]

Study of effectiveness of CaCo-2 cell line for influenza virus isolation was carried out. It was shown that the properties of this cell line strongly depended on the source of its origin and cultivation conditions. The infectious activity of the influenza viruses on CaCo-2 cell line was virtually the same as in the MDCK cell line. The rate of the viral isolation was virtually identical for both cell lines tested, but viruses from post-mortem materials were isolated only in CaCo-2 cell line. In general, the CaCo-2 line is believed to be a valuable cell line for virological research, particularly for influenza virus isolation.
