If 75 -day old swine fetuses got the parvovirus infection, mummification will be the result.
T
The acute Marek’s disease comes with neoplasm-formation.
T
The immunogenicity of different viruses is different.
T
The causative agent of Aujeszky’s disease causes encephalitis in humans.
F
There are four types of porcine circoviruses.
