Recently Jonas found a tick on his shoulder. A couple of days later, a large red ring appeared around the place where the tick had been. The ring is a clear symptom of Lyme disease caused by a bacterium called Borrelia that is transferred by ticks. The outcome of Lyme disease can be very bad if not treated immediately, but if treated in an early stage with antibiotics the infection is easily wiped out. In this video we find out how the antibiotic really works, and why it kills only the bacteria.
