Wide Dispersal and Possible Multiple Origins of Low-Copy-Number Plasmids inRickettsiaSpecies Associated with Blood-Feeding Arthropods
23 Jan 2010
Abstract excerpt
Plasmids are mobile genetic elements of bacteria that can impart important adaptive traits, such as increased virulence or antibiotic resistance. We report the existence of plasmids in Rickettsia (Rickettsiales; Rickettsiaceae) species, including Rickettsia akari, "Candidatus Rickettsia amblyommii," R. bellii, R. rhipicephali, and REIS, the rickettsial endosymbiont of Ixodes scapularis. All of the rickettsiae...
