Figure 1

Comparative genomic hybridization of 28 human and 43 ovine strains of B. parapertussis. Each column represents a strain, ordered according to a maximum-parsimony tree topology. Each row represents a microarray element (usually the average of duplicates), arranged in order according to the sequenced strain 12822 (represented in the far left column), with sequences not found in that strain below the red horizontal line. Three major clades (which received >95% bootstrap support; see Additional data file 3 for tree) are denoted by colored bars. Missing data are gray (display excludes elements with missing data from more than 35% of strains). RD21 includes chemotaxis and flagella genes that are not detected in ovine strains. In some cases, data for multiple different array elements for the same gene are shown.
