Lyme disease (Borrelia burgdorferi)

Test code: B0004 - Ultrasensitive qualitative detection of Borrelia burgdorferi by real time PCR. This assay detects all Borrelia genospecies within the designation Borrelia burgdorferi sensu lato, which includes those found in both North America and Eurasia.


Borrelia burgdorferi are gram-negative spirochete bacteria that cause Lyme disease. Spirochetes are a group of phylogenetically distinct bacteria that have a unique mode of motility by means of axial filaments (endoflagella).

Borrelia are divided into "genospecies" including B. burgdorferi sensu strict, B. garinii and B. afzelii. The term used to collectively describe all these genospecies is B. burgdorferi sensu lato. All North American isolates are genospecies B. burgdorferi sensu strict. B. garinii and B. afzelii are predominant in Europe and Asia, although all three genospecies have been found there.

B. burgdorferi invades the blood and tissues of various infected mammals and birds via the bite of ticks of genus Ixodes. The natural reservoir for B. burgdorferi is thought to be the white-footed mouse. Ticks transfer the spirochetes to deer, humans, and other warm-blooded animals after a blood meal from an infected animal. In most mammals, including humans, infection by B. burgdorferi can result in Lyme disease.

Culture detection of Borrelia is difficult because these organisms have fastidious growth requirements, and even under optimal conditions their growth is very slow. Diagnosis by serological means usually has a very low positive predictive value (Lakos et al., 2010). However, PCR is a highly specific and sensitive methodology for rapid detection of B. burgdorferi.


  • Help confirm the disease causing agent
  • Shorten the time required to confirm a clinical diagnosis of Lyme disease
  • Help ensure that animal facilities are free of Lyme disease
  • Early prevention of spread of Lyme disease among a facility
  • Minimize human exposure to Lyme disease
  • Safety monitoring of biological products that derive from susceptible animals

Preferred specimen types: 0.2 ml synovial fluid or CSF, or 0.2 ml fresh, frozen or fixed tissue, or tick.

Less preferred specimen types: 0.2 ml whole blood in EDTA (purple top) or ACD (yellow top) tube, or 0.2 ml urine

Contact Zoologix if advice is needed to determine an appropriate specimen type for a specific diagnostic application. For specimen types not listed here, please contact Zoologix to confirm specimen acceptability and shipping instructions.

For all specimen types, if there will be a delay in shipping, or during very warm weather, refrigerate specimens until shipped and ship with a cold pack unless more stringent shipping requirements are specified. Frozen specimens should be shipped so as to remain frozen in transit. See shipping instructions for more information.
