Borrelia burgdorferi
(the causative agent of Lyme disease)

This pathogenic organism is responsible for causing the illness, Lyme disease, a zoonotic, vector-borne, ailment, transmitted to humans by way of a tick bite. B. burgdorferi belongs to a group of bacteria, called spirochetes, whose appearance resembles a coiled spring.

B. burgdorferi bacteria can infect several parts of the body, producing different symptoms at different times. Not all patients with Lyme disease will have all symptoms, and many of the symptoms can occur with other diseases as well. If you believe you may have Lyme disease, it is important that you consult your health care provider for proper diagnosis.

If left untreated, infection can spread to joints, the heart, and the nervous system. Lyme disease is diagnosed based on symptoms, physical findings (e.g., rash), and the possibility of exposure to infected ticks; laboratory testing is helpful when used appropriately. Most cases of Lyme disease can be treated successfully with a few weeks of antibiotics. Steps to prevent Lyme disease include using insect repellent, removing ticks promptly, landscaping, and integrated pest management. The ticks that transmit Lyme disease can occasionally transmit other tick-borne diseases as well.
