Effects on Subsequent Quarantine of Imported Cattle Vaccinated with Bovine Virus Diarrhea Vaccine in Pre-export Isolation Facilities and Countermeasures
After breeding cattle imported into China vaccinated with vaccines containing inactivated Bovine viral diarrhea virus(BVDV)in pre-export isolation facilities,it would bring subsequent effects in quarantine. In this paper,the influence of follow-up quarantine work for this disease were analyzed as followed:BVDV isolation from serum samples was disturbed;There was ignorable effects for BVDV detection with antigen capture ELISA in pre-export isolation facilities;For cattle quarantine at the domestic quarantine and subsequent quarantine inspection in China,Erns AC-ELISA was much better than NS2-3 AC-ELISA for BVDV detection;Antibody responses to BVDV vaccines couldn't be distinguished from response of natural infection. the proposal of cancelling vaccination of BVDV should be canceled were put forward,and was accepted by the authorities of import and export countries.
