Figure 1From: Identification of Mycobacterium spp. of veterinary importance using rpoB gene sequencingNeighbor-joining tree generated from a 726-bp sequence of the rpoB gene from Mycobacterium isolates from 33 domestic and feral pigs and selected reference strains. Bootstrap values (as a percentage of 1000 replicates) are indicated at nodes. Scale bar indicates evolutionary distance in base substitutions per site.Back to article page
