Isolation of transmissible gastroenteritis virus from pharyngeal swabs obtained from sows at slaughter.
A virologic survey was conducted to determine the frequency of transmissible gastroenteritis (TGE) virus infection in farm-raised sows. Pharyngeal swab specimens collected in an abattoir were examined for TGE virus by inoculation onto swine-testes cell culures. The virus was detected in 61 (3%) of a sample of 2,058 Iowa sows after slaughter. All TGE viral isolates, given orally to 2- or 3-day-old pigs, caused acute gastroenteritis and in some cases death. All pigs that recovered from illness had serum antibody to TGE virus.
