Ruminant Parasitology

Investigation of Parasite Infections That Impact Livestock Production

ARS Bovine Functional Genomics Laboratory in Beltsville, MD and the Philippine Animal Health Center (PAHC), Bureau of Animal Industry.


  • Improved diagnosis of gastrointestinal nematodes by the use of a DNA-based, "multiplex" PCR technique that is simple, sensitive and rapid, and allows the user to simultaneously test for 5 different genera of GI nematodes infecting cattle or sheep and can be used on DNA isolated from parasite eggs.
  • Identification of genetic resistance markers that could be used to make informed breeding decisions in terms of minimizing the effects of the parasites on production.
  • Improved diagnosis of Trichinella in swine herds that would allow for better surveillance and control.
