Summary<\/span>
In the past histomonosis was very well controlled with Dimetridazole as a treatment and\/or Nifursol as feed additive. In the European Union both products were banned in 1995 and 2003, respectively. This was followed by the re-emergence of the disease in the recent years. In the present case a farm with two houses was affected by the disease. In each house 2620 hens and 2620 toms were kept, separated by wire mesh. At the 53rd day of age the toms in house 1 showed general clinical symptoms, accompanied by a slightly raised mortality, which sharply increased in the following days. At necropsy all dead birds showed lesions typical for histomonosis in caeca and liver. Histomonosis was diagnosed by histopathology and PCR. Within five days cumulative mortality was 25.1%. The hens kept at the same house didn\u0092t show any symptoms. At day 57 two toms, which were kept in house 2, died and showed similar symptoms and lesions. Within the next three days 48 more birds died. Again the hens in house 2 showed neither clinical signs nor mortality. Treatment trials using herbal products and a change of litter directly after the onset of clinical signs did not reduce the mortality. On day 62 the toms of both houses were euthanized by CO2<\/span> in closed containers. The hens were kept until they were slaughtered in week 16 and did not show any evidence of histomonosis.

Zusammenfassung<\/span>
In der Vergangenheit stellte die Histomonose wegen der Verf\u00fcgbarkeit von Dimetridazol zur Therapie und Nifursol als FuttermittelIzusatzstoff kein Problem dar. In der Europ\u00e4ischen Union wurde der Einsatz beider Produkte 1995 bzw. 2003 verboten. Seitdem trat die Krankheit wieder \u00f6fter auf. In dem hier beschriebenen Fall war ein Hof mit zwei St\u00e4llen von der Krankheit betroffen. In jedem Stall wurden 2620 Hennen und 2620 H\u00e4hne durch Maschendraht getrennt gehalten. Am 53. Lebenstag zeigten die H\u00e4hne in Haus 1 unspezifische klinische Symptome und eine geringgradig erh\u00f6hte Mortalit\u00e4t, die in den folgenden Tagen rasch stieg. Bei der Sektion zeigten alle Tiere f\u00fcr die Histomonose typische L\u00e4sionen in Blindd\u00e4rmen und Lebern. Die Histomonose wurde histopathologisch und mittels PCR nachgewiesen. Nach f\u00fcnf Tagen betrug die kumulative Mortalit\u00e4t 25,1 %. Die Hennen, die im selben Stall gehalten wurden, zeigten keine Symptome. Am 57. Lebenstag verendeten zwei H\u00e4hne aus Stall 2. In den n\u00e4chsten drei Tagen verendeten 48 weitere Tiere. Alle zeigten bei der Sektion \u00e4hnliche L\u00e4sionen. Die Hennen im selben Stall zeigten wieder keinerlei Symptome. Behandlungsversuche mit Kr\u00e4uterprodukten und ein Wechsel der Einstreu direkt nach Ausbruch der Krankheit f\u00fchrten nicht zu einer Verringerung der Mortalit\u00e4t. Am 62. Tag wurden die H\u00e4hne beider H\u00e4user mit CO2 <\/span>in geschlossenen Beh\u00e4ltern euthanasiert. Die Hennen wurden bis zur Schlachtung im Alter von 16 Wochen gehalten, ohne Symptome einer Histomonose zu zeigen.
