carries the bacterium (Borrelia sp.) … coli, contain a single circular DNA molecule that makes up their entire genome, recent studies have indicated that some prokaryotes contain as many as four linear or circular chromosomes.
Which species of bacteria has two chromosomes?

Do bacteria have 1 chromosome?
Bacteria usually have one circular chromosome of a few megabases in size. They often have plasmids whose size range from a few to one hundred or more kilobases. In some cases, the plasmids approach the size of chromosomes.
Do bacteria have chromosomal DNA?
Most bacteria have a haploid genome, a single chromosome consisting of a circular, double stranded DNA molecule.
