| first molecular characterization of bovine leukemia virus infections in the caribbean. | bovine leukemia virus (blv) is a retrovirus that causes enzootic bovine leucosis. to investigate the presence and genetic variability of blv in the caribbean for the first time, we preformed fluorescence resonance energy transfer (fret)-pcr for the pol of blv on dna from whole blood of cattle from dominica, montserrat, nevis and st. kitts. standard pcrs with primers for the env were used for phylogenetic analysis of blv in positive animals. we found fret-pcr positive cattle (12.6%, 41/325) on do ... | 2016 | 27977761 |
