title: [The control of Aujeszky's disease using surface vaccination. 2. Serologic studies of the occurrence of latent infection by Aujeszky's disease virus in fattening swine].
abstract: The aim of the study was to prove in a region in the North-West of Germany that there is the possibility to decrease the prevalence of latent Aujeszky's Disease infections by means of a systematic vaccination. For this, the most important precondition of the success in a high population immunity that is maintained also in the finishing pig until slaughter. Since it is known that maternal antibodies interfere with the active immunization in the prefattening period, procedures were to be found that guarantee a high immunity in spite of the colostral antibodies. The results of the study show that the existing recommendation for vaccinating fattening pigs are sufficient for the prevalence of latent infections. They also confirm the necessity to carry out a check- and slaughter policy at the end of the eradication program.
