Plasmid lp17 organizational subtypes. Plasmids are represented as in Fig. 2, with different background colors indicating regions of nonhomologous DNA. The organizational subtypes (see text) are indicated by Roman numerals on the right, and isolates that carry each type are indicated above the maps. Some paralogous gene families are indicated in boxes above each map [17, 19], and black bars below indicate some of the similarities to other B. burgdorferi linear plasmids
