Genome Structure

The Borrelia burgdorferi genome contains 1,521,208 base pairs with the number of G+C bases totaling 28%. It has a total of 22 DNA molecules including 21 extrachromosomal DNA elements, the largest known number of any bacterium (1). These include 12 linear and 9 circular plasmids which range from 5 to 56 kilobases (2). The plasmids contain a total of 1706 genes, including many pseudogenes, which suggests that the genome is actively evolving.
