W. Szweda et al., The efficacy of the vaccination-eradication programme in maintaining a pigfarms status as being free from Aujeszky's disease virus, MED WETER, 56(7), 2000, pp. 447-451
The aim of this study was to evaluate the significance of control serologic
al examinations in maintaining a pig farm's status as being free from Aujes
zky's disease virus - Herpesvirus suis type 1 (SHV-1), through realising a
vaccination - eradication programme. The studies were carried out in the bi
ggest large-scale pig farm in Poland - farm B., having over 2000 reproducti
ve pigs, where SHV-1 was eliminated using the above programme and at which
further procedures in preventing SHV-1 reintroduction to farm B. were expla
ined. Blood samples for serological examinations were taken randomly from 5
% reproductive pigs and 5 fattening pigs from every fattening house. Serolo
gical examinations using gE-ELISA - Pseudorabies Virus gpI Antibody Test Ki
t (Herd Chek Anti - PRV gpI), IDEXX Lab. Inc. USA were performed. in 1999,
three control examinations 4 months apart were undertaken on 653 pigs. Sero
logical examinations revealed that the pig herd in farm B, was free from SH
V-1, which proved the efficacy of the vaccination - eradication programme.
The article discusses the risk factors involved in the realisation of Aujes
zky's disease (AD) eradication programmes as well as stressing the need to
continue pig vaccinations in herds free from SHV-1 where there exists the r
isk of reinfection. It also emphasises the necessity to start the realisati
on of national AD eradication programme as soon as possible in the light of
the imminent acceptance of Poland into the European Union.
