Molecular detection of porcine kobuviruses in Italian swine

In this study, fecal specimens (n = 260) collected from Italian healthy pigs aged between 6 and 10 months were screened by RT-PCR using generic kobuvirus primers. Porcine kobuviruses (PKVs) were detected in 3.85% of the samples tested. Based on the analysis of the partial 3D gene, the Italian sequences identified here were more closely related to PKVs previously identified in Japan, Thailand, Korea, China and Brazil than to the European PKVs recently detected in Hungary and in the Netherlands.
