Lime is caused by a bacterium called Borrelia burgdorferi and transmitted to human beings and other host animals through a bite of an infected tick. Being a bacterial infection, Lyme disease is therefore not a virus. However, after several studies and extensive research, especially trying to find out why the disease does not respond to antibiotic treatment, it was established that the disease might actually not only be caused by the bacterium alone, thus not a distinct disease. Instead, the presence of other viral infections like Chlamydia and cytomegalia as well as exposure to metals and toxins has been established to weaken the immunity resulting into a combination of symptoms that are generally referred as Lyme disease. In this regard, as much as Lyme disease can be said to be a bacteria disease, some viruses are responsible for weakening the immunity for the bacteria to exhibit its symptoms.
