Dual infections with both bovine viral diarrhea virus (BVDV)-1 and-2 seem to be unusual. The aim of this study was to describe an infection with both BVDV genotypes in a stillborn calf. Virus isolation and phylogenetic analyses of the 5´UTR and NS5B regions confirmed the presence of BVDV-1b and-2b in spleen and lung, whereas BVDV-2b was also detected in brain, heart, liver, kidney and, fluid of cavities. These results confirm that dual infections with both BVDV-1 and BVDV-2 species can occur naturally and their tissue distribution can be different.
