Dotplots of 7 Brucella and Ochrobactrum anthropi genomes against the two chromosomes of B. microti. B. microti chromosomes are in abscissa of each plot and the corresponding chromosomes of target genomes are in ordinate. In chromosome 2 plots, the 12 kbp region specific to B. microti is circled. Plots for B. abortus S19 and B. abortus 9–941 are not shown because of their similarity to the plot for B. melitensis biovar abortus 2308. In the case of O. anthropi, the dotplots of the two chromosomes of B. microti against the 2 large chromosomes of O. anthropi are shown. O. anthropi plasmids are not shown as they have no similarity with B. microti chromosomes.
