R. Peshev et al., INTERFERENCE ACTIVITY OF BOVINE HERPES-VIRUS-1 STRAINS AGAINST AUJESZKYS-DISEASE VIRUS IN CELL-CULTURES, Comparative immunology, microbiology and infectious diseases, 20(2), 1997, pp. 171-175
The interference-inducing activity of different low- and high-virulenc
e strains of bovine herpes virus 1 (BHV-1) against Aujeszky's disease
virus was studied by a parallel titration on permissive and non-permis
sive cell culture. The low-virulence BHV-1 strains possessed better in
terference-inducing activity than the high-virulence strains. An inter
ference blocking test (IBT) was developed for the detection of BHV-1 a
ntibodies in bovine sera. Comparative results of IBT and the virus neu
tralisation reaction did not show statistically reliable differences.
