This contribution proposed by a multidisciplinary group of veterinary and political scientists gives an analysis of the transformations of an epidemiosurveillance system dedicated to animal diseases, when confronted to new emerging threats in the wake of global changes, within the frame of risk management. The research field refers to the emergence of bluetongue virus serotype 8 in 2006 in Belgium. This research is complemented with the results of a recent survey based on Delphi method involving relevant public servants and scientists, which showed that most of the means proposed by the authorities are based on the logic of known risk management. However we can identify attempts for renewal and organisational learning, especially with the proposal of a new vigilance system. This system develops two dimensions (prevention and anticipation of the catastrophe) and tries to accommodate the surveillance system reactivity against uncertain events. Finally the article draws two drivers for change, by admitting the persistence of unavoidable uncertainty and by recognising the importance for opening up expert knowledge. [less ▲]

Cattle are commonly subclinically infected following natural or experimental infection with bluetongue virus (BTV). The introduction of BTV serotype 8 (BTV-8) in Europe has been characterized by the manifestation of clinical signs in infected cattle. In order to study the pathogenesis of BTV-8 in this host, an animal model able to reproduce the clinical manifestations of the disease is required. In this work, two calves were subcutaneously and intravenously injected with a low passage cell-adapted strain of BTV-8. Both calves showed typical bluetongue clinical signs, including pyrexia, ocular discharge, conjunctivitis, oral mucosal congestion, development of ulcers and necrotic lesions on the lips and tongue, submandibular oedema, coronitis and oedema of the coronet and pastern region. A score was assigned depending on the severity of the lesions and a total clinical score was calculated for each animal daily and at the end of the experiment. Both calves became viraemic 24h post-infection and seroconversion occurred between 7 and 11 days P.I. In this study we present the development of a protocol of infection in calves able to reproduce the severity of the lesions observed with BTV-8 in field conditions. [less ▲]
