Figure 1From: Evaluation of the HOOF-Print assay for typing Brucella abortus strains isolated from cattle in the United States: results with four performance criteriaNeighbor-joining dendrogram of clustered HOOF-Print genotypes. Genotyped were clustered into groups based on the differences in the numbers of repeat units at the eight VNTR loci. Biovars are differentiated by colored text: black = biovar-1; green = biovar-2 and red = biovar-4.Back to article page
