Description

Transmissible gastroenteritis virus or Transmissible gastroenteritis coronavirus (TGEV) is a coronavirus which infects pigs.

In piglets less than 1 week old, the mortality rate is close to 100%. The pathology of TGEV is similar to that of other coronaviruses. Once the virus infects the host, it multiplies in the cell lining of the small intestine resulting in the loss of absorptive cells that in turn leads to shortening of villi. The infected swine then have reduced capability for digesting food and die from dehydration.
