None of the employees on this farm had ever seen TGEv before, but were concerned that is what they were seeing.
Clinical case of the world
Ileitis can take different forms, and it is frequent that a subclinical and a more severe and clinical form coincide.
This particular case occurred in a multisite farrow to finish operation in South Western Ontario, Canada.
One month after the beginning of the outbreak of reproductive failure in sows, acute respiratory disorder and diarrhoea that was non-responsive to antibiotics started in weaned pigs aged 6-8 weeks...
There was a sudden increase in mortality in a site 2 farm with the loss of the "biggest piglets" in the group.No particular symptomatology was seen but every day some dead piglets were found.
A sudden death of animals, with no prior symptoms of disease, and clinical symptoms such as massive facial, ears and forechest oedema, as well as an increase of body temperature to 41.5ºC, were observed.
A cough outbreak appeared in 8-9 weeks old piglets. It apparently was a "normal" outbreak that could be solved with a few days of antibiotic but the pigs did not respond to the treatment.
