FIG. 1.

Organization of the hagA-hagB region. Divergent transcription is noted by arrows. Independent insertion mutations that define the genes are denoted by triangles. Open reading frames adjacent to hagA and hagB are noted by their predicted putative products. The exact locations of the individual insertions (given alphanumeric designations in the figure) are matched with the B. avium 197N genome (27) coordinates (BA) as follows: P207/G145, BA3063020; P206b, BA3063348; P225, BA3063666; P218, BA3064152; P215b, BA3064256; P208a, BA3065210;P212a, BA3065504; P205a, BA3066299; and P201a, BA3066509.
