Bilan de la flambée d'histomonose dans les élevages français de dinde standard, après 2003

Abstract : Out of the news for several decades in standard turkey production, histomoniasis has made a dramatic comeback since, in March 2003, the Council of Europe banned the use of Nifursol, the last of the effective molecules used preventively against Histomonas meleagridis in animals destined for human consumption. An epidemiological field survey, based on several questionnaires and samples, was realised both by the National Veterinary School of Lyon (ENVL) and the Comité Interprofessionnel de la Dinde Française (CIDEF). It has brought to light more than 100 outbreaks of histomoniasis in France from April 2003 to June 2006. Most of these cases were in the North-West of France, which is the principal farming area for turkeys. The results showed a seasonal effect with the majority of cases occurring during the hottest months, from April to September. A very high number of cases were found among birds from 4 to 8 weeks of age, but there were some cases in younger (3 weeks) and much older birds (up to 17 weeks). The mortality rate in standard turkey flocks was mostly below 10%, but was above 30% in nearly 20% of cases. These cases were dramatic for breeders. The study of survival curves (daily evolution of the number of living animals) had shown several profiles: we can think that the disease may evolve by an acute way (high slope) or by a chronic way (middle or low slope). A preliminary analysis of the survival data had shown that liver lesions are systematically present in the cases with high slope profiles. Moreover, the enteric diseases (necrotic enteritis, non specific enteritis or coccidiosis) tend towards to be more frequent in these profiles.
