Chromosome and Megaplasmid Sequences of Borrelia anserina (Sakharoff 1891), the Agent of Avian Spirochetosis and Type Species of the Genus.

Sequences of the linear chromosome and plasmids of Borrelia anserina, the cause of avian spirochetosis of poultry, revealed a smaller genome than those of other Borrelia spp. transmitted by argasid ticks. Missing or disrupted genes included a dam methylase and those in the pathway for synthesis of phospholipids from glycerol.
