Infection of farmed pigs with porcine kobuviruses in Italy
- 290 Downloads
Two-hundred eight swine fecal samples from six Italian farms were tested using a kobuvirus-specific RT-PCR with primers that amplify a region within the 3D gene. All farms were kobuvirus positive, with prevalence rates ranging between 24 % and 84 %. Overall, 57.5 % of asymptomatic pigs and 49.7 % of animals with diarrhea were positive for kobuvirus. Sequence analysis showed a different predominant strain circulating on each farm and indicated that the strains detected were related to both European and Asiatic strains. A possible pathogenic role of kobuvirus should be investigated further, since infections with this virus occur frequently in pigs of different ages.
