FIG. 2.

Physical maps of 22 kb of the chromosome of Coxiella burnetii (accession number NC_002971) and a corresponding 9-kb region of an Amblyomma americanum bacterium (DQ912980). The arrows correspond to the lengths of the open reading frames (ORFs) and the presumed direction of transcription. Black arrows indicate ORFs found in both sequences. The numbers at the ends of the C. burnetii sequence are the genome nucleotide positions. ORFs with matches to known genes, e.g., dnaK, or with a protein family of presumed function are indicated. ORFs designated by numbers alone indicate hypothetical proteins of C. burnetii (14). Bar, sequence length.
