See also: 6 July 2006, 29 June 2006

Immediate notification report

Information received on 26 July 2006 from Dr Miklós Süth, Chief Veterinary Officer, Ministry of Agriculture and Rural Development, Budapest:

Report date: 26 July 2006.

Reason for immediate notification: re-occurrence of a listed disease or infection in a country.

Date of first confirmation of the event: 24 July 2006.

Date of start of the event: 4 July 2006.

Clinical disease: no.

Nature of diagnosis: laboratory.

Details of outbreak:

First administra-tive division (county) Lower administra-tive division (veterinary district) Type of epide-miolo-gical unit Name of the location Latitude Longitude Date of start of the outbreak Spe-cies Number of animals in the outbreak
susceptible cases deaths destroyed slaugh-tered
Hajdú-Bihar Tiszacsege farm Hortobágy 47.3609şN 21.0607şE 4 July 2006 ovi 2,115* 1 0 1 0

* 1,960 ewes, 55 rams and 100 young sheep under 12 months

Description of affected population: a sheep aged 37 months. The head of the sheep had been sent to the Central Veterinary Institute (CVI) in Debrecen within the framework of the National Monitoring Programme for Transmissible Spongiform Encephalopathies.

In the affected farm, two flocks are kept in separate buildings. The positive animal originated from the first flock, which contained 1,193 sheep (1,038 ewes, 55 rams, 100 young sheep under 12 months) when the event started. In the first flock 46 sheep (30 ewes and 16 young animals) have died until now. Samples from 28 dead ewes were sent to the Central Veterinary Institute (CVI) in Debrecen and all results were negative. (The other two ewes were unsuitable for testing). The second flock contained 922 young female sheep when the event started, but until now only two of them have died. These animals are not the progeny of ewes in the first flock, and originated from a different holding.

Diagnosis:

Laboratory where diagnostic tests were performed Species examined Diagnostic tests used Date Results
Central Veterinary Institute (CVI), Debrecen ovi Biorad TeSeE rapid test 7 July 2006 positive
Central Veterinary Institute (CVI), Budapest ovi immunoblotting 20 July 2006 positive

Primary discriminatory immunoblotting indicated that the case could be ascribed to the atypical form of scrapie. The genotyping of the animal is in progress. The CVI will send samples to the European Community Reference Laboratory for further investigations.

Source of outbreak or origin of infection: unknown or inconclusive.

Control measures

A. Undertaken:

- quarantine;

- movement control in the affected farm;

- destruction of the whole body of the slaughtered sheep as "specified risk material".

B. To be undertaken:

- stamping out: the whole population of the first sheep flock on the affected farm will be killed soon and samples will be taken from the killed animals according to Annex III, Chapter A, Part II, point 5 of Regulation (EC) No 999/2001. The whole carcasses of these animals will be destroyed as category 1 material in line with Regulation (EC) No 1774/2002. If the atypical scrapie case is confirmed by the CRL and the result of the epidemiological inquiry confirms that there were not any movements from the first flock to the second one, the animals in the second flock will not been killed.

- screening;

- disinfection of infected premises/establishment(s).

Final report: no.
