Eradication of Infectious Bovine Rhinotracheitis Virus (Bovine Herpesvirus 1) from a Herd of Beef Cattle

摘要

Infectious bovine rhinotracheitis virus was eradicated from a 150 cow beef herd at the Animal Diseases Research Institute, Lethbridge, Alberta. Tests used to accomplish this included standard and modified serum-virus neutralization tests and an enzymelinked immunosorbent assay. These results and those of preliminary pilot studies in the herd and in a nonvaccinated, infectious bovine rhinotracheitis-infected 450 cow beef herd suggest that eradication of infectious bovine rhinotracheitis infection can be considered as a practical control alternative to vaccination, and that young animals in purebred herds could be monitored serologically and isolated, to enhance their eligibility for entry into artificial insemination studs or for export.
