Genetic typing of bovine viral diarrhea virus isolates from Costa Rica
Abstract
Sixteen bovine viral diarrhea virus (BVDV) isolates collected in Costa Rica between 1987 and 2006 from dairy
cattle were analyzed by RT-PCR and determined to belong to BVDV species 1. Furthermore, eleven of these
isolates were genotyped using the nucleotide sequences of the Npro region of the viral genome. Phylogenetic
analysis indicated that all samples examined clustered within the BVDV-1b subtype. Dieciséis aislamientos del virus de la diarrea viral bovina (BVDV) recolectados entre 1987 y 2006 de hatos
lecheros de Costa Rica fueron analizados mediante la técnica de RT-PCR y determinados como pertenecientes
al genotipo 1. Once de estos aislamientos fueron genotipificados utilizando la secuencia de nucleótidos de
Npro del genoma viral. El análisis filogenético determinó un único genogrupo en estos aislamientos, BVDV-1b.
