Figure 3From: Sca 1, a previously undescribed paralog from autotransporter protein-encoding genes in Rickettsia speciesCurrent knowledge on the distribution of the ompA, sca 1, sca 2, sca 4, and sca 5 genes among the 20 validated Rickettsia species. Green dots indicate complete genes, whereas blue dots indicate split genes, yellow dots indicate gene fragments, and red dots indicate absent genes.Back to article page
