Type C influenza virus

According to the morphology, type and function of its structural components the segmented genome of type C influenza virus is similar to that of influenza viruses A and B. However, type C influenza virus differs from them by the reticular structure of virion surface, absence of the surface glycoprotein neuraminidase, the presence of unusual for Orthomyxoviridae cell receptors and the ability to induce an essentially moderate respiratory illness.
