The pig infectious gastroenteritis
Pig infectious gastroenteritis (TGE) is caused by the pig infectious gastroenteritis virus (TGEV), belonging to coronavirus coronavirus genera. Virus particles assumes the circular, oval, or polygon, the diameter is about 90-200 nm, double membrane, petal sample protrusions on the outer membrane. For single strands of RNA, the virus nucleic acid complete TGE virus in sucrose density of 1.19 1.218 g/ml.

porcine parvovirus (PPV)
Porcine parvovirus (PPV) is a kind of important virus, parvovirus genera belong to small virus, the virus particle without posterior capsule, about 20 to 25 nm in diameter, genome into a single linear DNA molecules. PPV has stronger ability to resist the external environment, the resistance to heat, acid, fat solvents and organic solvent, which enables the virus to survive and spread in a variety of conditions.
