The primary interest of our laboratory is studying mechanisms of perturbation of the immune system by microbes and environmental and microbial toxins. Under this broad heading, there are four major active projects:

  • Immunotoxicology – adverse effects of polycyclic aromatic hydrocarbons on bone marrow cells and hematopoiesis;
  • Bovine respiratory disease – focus on viral/bacterial synergism and the effects of Mannheimia haemolytica and its leukotoxin on the activities of bovine leukocytes;
  • Haemophilus somnus – adverse effects on bovine endothelial cells as it relates to vasculitis;
  • Host and bacterial factors that influence the pathogenesis of gastrointestinal listeriosis.
