| dcterms.abstract | Aujeszky's disease is a contagious disease of domestic and wild animals of viral
etiology, caused by Porcine herpesvirus type-1. The causative agent is classified in
the family Herpesviride, sub-family Alphaherpesvirinae, the genus Varicellovirus.
The cause of the disease has a special affinity for the nervous tissue. The most frequent
animal species affected by disease are pigs, while in other susceptible animal species
the disease appears sporadically. The illness arises in an acute form; it rapidly appears
and spreads rapidly through the susceptible population, especially among the younger
categories. Older pigs, after surviving, become carriers and can spread virus without
visible symptoms of the disease. Aujeszky's disease is mandatory for reporting, and
in terms of economic damage, one of the most important diseases is pigs. The
establishment of herds free of Aujeszky's disease is particularly important when it
comes to the international trade of pigs, pig meat and pork products. In the event of
the occurrence of the disease, extensive control measures are applied which include:
identification of pigs, movement control and segregation of healthy pigs from
affected, stamping out of suspicious and diseased animals etc. Prevention of
Aujeszky's disease is achieved by vaccination of pigs, especially with the use of DIVA
vaccines. With the application of the DIVA strategy in many EU countries and
developed countries worldwide, Aujeszky's disease has been successfully eradicated.
The selection of an appropriate control strategy, i.e. measures of control and
eradication are conditioned by the production technology, the way of keeping pigs,
the distribution of farms and pig holdings village, applied biosecurity measures and
with the possible pathways of transmission of the virus. The aim of the research was
to examine the dynamics of diseases and disease control strategies in the Republic of
Serbia under the conditions of a simulated natural environment in which Aujeszky's
disease is being persisted by applying a stochastic spatial model. During the
simulation of the epizootic, different epizootiological indicators were analyzed, such
as the number of infected and culled pigs, the time frame of the duration of the
epizootic, the number of infected households and the necessary resources for the
implementation of disease eradication measures. | En |
