Epidemic parotitis is an acute viral disease characterized by damage to one or both parotid salivary glands. The pathogen was isolated in 1934 by K. Johnson and R. Goodpasture from the saliva of a patient with mumps by infecting monkeys into the salivary gland duct.
The virion of the influenza C virus has the same shape as viruses of types A and B. However, it differs from them not only in its antigenic properties, but also in a number of other features.
The structure of the influenza B virus virion is similar to the structure of the A virus. The genome consists of 8 fragments encoding 3 non-structural and 7 structural proteins.
The virion is spherical in shape and has a diameter of 80-120 nm, its molecular weight is 250 MD. The genome of the virus is represented by single-stranded fragmented (8 fragments) negative RNA...
