Multilocus allele analysis of Brucella species and biovar type strains. Graphical representation of the alleles generated by fluorescent tagged-PCR amplification of the genomic DNA of Brucella species and biovars. The allele number reflects the total number of repeats calculated for each locus. Each lane is the compilation of data from the independent amplification of each of the eight VNTR loci. The star next to the VNTR Locus-4 allele in some samples shows a match with the alternative allele ladder indicating an 11-bp insertion in the non-repeat region of the amplicon.
