|Comparison of CF titers against 3 Maedi-Visna strains, vaccine strain K796 and 2 local strains 10B and 7W from 2 sheep of the flock in Cyprus|
|Titer of serum from one sheep infected intrapulmonarily with 300.000 TCID 50 of virus K796||Virus strains|
|Serum 13 months after infection with K796||128||16||8|
|Serum 3 years after infection with K796||256||32||16|
|Titer of serum from one naturally infected sheep in Cyprus||16||128||128|
* In these CF tests serial 2 fold dilutions of sera ranging from dilutions 1/4 - 1/512 were tested against the 3 strains. Four-fold or larger difference in titer is significant.
