ABSTRACT

INTRODUCTION:

Occurring for the first time in 1986 in the United Kingdom, bovine spongiform encephalopathy (BSE), the so-called "mad-cow disease", has had unprecedented consequences in veterinary public health. The implementation of drastic measures, including the ban of meat-and-bone-meal from livestock feed and the removal of specified risk materials from the food chain has eventually resulted in a significant decline of the epidemic. The disease was long thought to be caused by a single agent, but since the introduction of immunochemical diagnostic techniques, evidence of a phenotypic variation of BSE has emerged. Reviewing the literature available on the subject, this paper briefly summarizes the current knowledge about these atypical forms of BSE and discusses the consequences of their occurrence for disease control measures.

INTRODUCTION:

L'encéphalopathie spongiforme bovine (ESB) dite aussi "maladie de la vache folle", apparue pour la première fois en 1996 au Royaume-Uni, a eu des conséquences sans équivalent pour le service public vétérinaire. La mise en application de mesures de lutte drastique, telle l'interdiction d'affourager les animaux de rente avec des farines animales et le retrait de la chaine des aliments de matériels à risque a conduit à un recul significatif de l'épidémie. Durant longtemps on a considéré que la maladie n'était causée que par un seul type de l'agent infectieux. Avec l'introduction de techniques de diagnostic immunochimiques, on a toutefois des indices de variantes phénotypiques de l'ESB. Le présent article résume la littérature disponible et fait le point des connaissances quant à ces variantes atypiques de l'ESB; on y discute également les conséquences possibles de leur apparition quant à la lutte contre la maladie.
