Abstract

A unique genotype of Rickettsia parkeri, designated R. parkeri strain Black Gap, has thus far been associated exclusively with the North American tick, Dermacentor parumapertus. The compete genome consists of a single circular chromosome with 1,329,522 bp and a G+C content of 32.5%.

FIG 1
Mauve alignment of complete genomes from Rickettsia parkeri strains Portsmouth, Atlantic Rainforest, and Black Gap. Dark purple locally colinear blocks (asterisks) in R. parkeri Atlantic Rainforest and R. parkeri Black Gap contain a transfer operon that includes traB (partial in Black Gap), traC (partial in Black Gap), traW, traU, trbC, traN, and traF. The gray block (R) was added to the Mauve output figure and contains a larger transfer operon found only in Atlantic Rainforest, which includes traB to traF, traH, traG, a tetratricopeptide repeat-containing protein, the Flp pilus assembly complex, and ATPase components tadA, traA, and traD. The transfer operons are absent in R. parkeri Portsmouth.
