Domaines d'expertise :

  • microbiologie de l'intestin des animaux et salubrité des aliments de prérécolte : études portant sur l'écologie des bactéries commensales et des pathogènes d'origine alimentaire et leurs éléments d'interaction avec les animaux hôtes en vue de l'élaboration de stratégies et de techniques nouvelles de lutte contre ces pathogènes et de la réduction de l'utilisation prophylactique d'antibiotiques dans la production animale pour l'alimentation humaine
  • détoxification de la vomitoxine dans les aliments pour animaux par les bactéries de l'intestin en production porcine

Projets en cours :

  • Études génomiques écologiques et fonctionnelles relatives à l'élimination de la clostridiose de la volaille
  • Mise au point de méthodes biologiques pour l'élimination des pathogènes bactériens dans la production de nourriture pour animaux : étude de l'utilisation de bactériophages, de probiotiques et d'huiles essentielles
  • Utilisation de probiotiques pour la lutte contre la salmonelle et d'autres pathogènes chez l'humain dans la production de poulets à griller
  • Huiles essentielles comme solution de rechange aux antibiotiques alimentaires : microencapsulation pour l'introduction efficace des huiles dans l'intestin des porcs
  • Identification et caractérisation des micro-organismes de transformation de la vomitoxine dans l'intestin des poulets et application à la détoxification de la vomitoxine dans l'alimentation des porcs
