Quasispecies in the 5′ untranslated genomic region of bovine viral diarrhoea virus from a single individual

Abstract excerpt

The variability of the 5' untranslated genomic region (5'UTR) of bovine viral diarrhoea virus (BVDV) RNA obtained from a single individual was analysed. Lung, kidney and spleen tissues from a naturally infected foetus were used as the source of viral RNA. A fragment of 288 bases of the internal ribosome entry site from the BVDV 5'UTR was amplified by RT-PCR using a proofreading DNA polymerase. PCR products were...
