Epidemiology

Source of infection
  • Unknown or inconclusive
Epidemiological comments This farm is situated within the surveillance zone, at about 9 km from the earlier confirmed outbreak in Csongrád county (in Szentes-Lapistó).

In the morning of 26 January 2007, a bacterial infection (Mycoplasmosis) was suspected on the basis of post-mortem examinations. For safety reasons, the official movement control of the flock was ordered and samples were sent to the Veterinary Diagnostic Directorate of the Central Agricultural Office.

On the late afternoon of 26 January 2007, the clinical signs and post-mortem examinations carried out on spot did not exclude the suspicion of HPAI virus to be present in this geese flock. The same day, the affected geese showed neurological signs explicitly. Therefore, the killing of whole flock was ordered.

On 27 January 2007, the whole flock of the affected farm was killed as well as the flocks of four backyard farms within the 1-km-radius zone around the affected farm.
