USAgNet - 08/25/2009
The veterinary authorities in Chile have reported two cases of influenza A in turkeys to the World Organization for Animal Health. It is has been confirmed to be the H1N1 sub-type.
The Chilean veterinary authority sent an Immediate Notification to OIE dated August 21. The report describes two cases of what is described as 'influenza A virus' in turkeys in the state of Valparaiso.
One case is in Nogales. It involved illness in 12,248 breeding turkeys of a flock of almost 30,000. An abnormal decrease in the laying rate was observed but no respiratory signs or increased mortality.
Symptoms were observed on July 23 in another flock of breeding turkeys in Valparaiso. More than 24,000 birds out of another flock of 30,000 birds were affected. Egg production fell from around 70
percent to 31 percent, and shell quality deteriorated. Again, no respiratory signs or increased mortality were observed.
The affected farms are turkey breeding premises belonging to the same company, vertically integrated, where appropriate biosecurity measures are applied.
The affected premises were systematically monitored through serological testing.
