Abstract:
Wild boars are one of the widest-ranging mammals worldwide and represent
reservoirs for many important viruses. Disease outbreaks in domestic swine
are often described as a consequence of contact with wild boars, and
traditional rearing conditions are a particular risk factor. Examples of
such diseases include classical swine fever (CSF), African swine fever
(ASF), Aujeszky?s disease (AD), and diseases caused by porcine circoviruses
and parvoviruses. Some viral infections causing high mortality rates are
easily noticeable and thus reported, though many viruses infecting wildlife
are insidious impacting survival rates and reproduction in wild animals.
Samples from wild boars for laboratory testing are usually collected
postmortem and include various tissues or blood sera. The recovery of viable
viruses during virus isolation depends on the virus species and the
condition of the sample. Since this method does not yield timely results,
most diagnostic procedures are based on PCR or antigen detection methods.
Serological surveys are inexpensive and appropriate for prevalence studies.
When interpreting the results of diagnostic tests, both virus and host
characteristics, and the epizootiological situation must be accounted for.
Disease control techniques such as fencing or feeding wild boars cause
animal aggregation and give rise to population density which favors pathogen
maintenance in the environment. Hunting reduces the number of susceptible
animals and is helpful as an additional control measure and for sampling.
Available data on infectious disease dynamics in wild boars is scarce, and
constant knowledge improvement on pathogenesis, clinical symptoms, risk
factors, and adequate control measures are required.
