Presumptive diagnosis is based on the clinical signs but as these are not always present, the diagnosis is confirmed by laboratory isolation of the virus. The virus grows readily in cell cultures, where its presence can be confirmed by electron microscopy and immunolabelling Figure 1 Once isolated, the strain type can then be determined.
