Lyme disease is an infectious disease that is caused by bacteria. It is transmitted to humans and some animals by ticks.
Lyme disease or Lyme Borreliosis is an infectious disease caused by bacteria belonging to the spirochetes: Borrelia burgdorferi, Borrelia garinii, Borrelia afzelii, Borrelia japonica. It is transmitted to humans and some animals by ticks of the genus Ixodes.
Not every tick spreads the bacteria causing Lyme disease and not every bite by a tick carrier will cause the disease. The latest research show that about 20 percent of the examined ticks in Poland are infected with Borrelia burgdorferi spirochetes (Medical University of Silesia in Katowice, Poland) and the risk of infection after being bitten by a tick carrier reaches a small percent.
