I. Capua et al., CHARACTERIZATION OF AUJESZKYS-DISEASE VIRUSES ISOLATED FROM DOMESTIC-ANIMALS AND FROM A WILD BOAR (SUS-SCROFA) IN ITALY BETWEEN 1972 AND 1995, Veterinary microbiology, 57(2-3), 1997, pp. 143-149
Following the isolation of a group I Aujeszky's disease virus from a w
ild boar in 1993, an investigation was carried out on 30 Italian Aujes
zky's disease viruses (ADV's), isolated over a 23-yr period in 12 Ital
ian regions, by means of restriction endonuclease analysis. All strain
s isolated between 1972 and 1984 belong to group I. From 1984 onwards
group II isolates (II and II intermediate) replace group I isolates. T
he isolation of a group I virus in 1993 from a wild boar supports the
hypothesis that ADV's may persist for several years in wild boar popul
ations and that wild boars should therefore be considered reservoirs o
f Aujeszky's disease virus. (C) 1997 Elsevier Science B.V.
