Researchers of a new study said that if you think pain caused by Lyme disease is hardly bearable then the new tick-borne infection is even more severe.

The new tick-borne infection occurs from Borrelia miyamotoi bacteria. Study's lead researcher Dr. Phillip J. Molloy, medical director at IMUGEN, Inc, along with team members took blood samples of 51 patients from tick-borne infected areas and assessed them.

The researchers said that symptoms of the disease caused by the new disease are similar to Lyme disease. But in some patients, the symptoms are quite worse. In fact, some patients have to be hospitalized.

After carrying out polymerase chain reaction (PCR) tests, patients were diagnosed with Borrelia miyamotoi disease. In 1995, spiral-shaped bacteria, Borrelia miyamotoi, were discovered in ticks by Japanese.

Majorly, they were found to be in two species of North American ticks - the black-legged tick and the deer tick. Because its symptoms are akin to that of Lyme disease, therefore, they were mistaken as the latter.

But experts said that both the disease differ in some ways. The researchers said that weather could be a reason in the spread of BM disease. Borrelia miyamotoi disease can be treated with the same drug that fights Lyme virus, the doxycycline.

Two more new tick-borne viruses have been identified, the Heartland virus and the Bourbun virus. But the main species responsible for the cases are yet to be identified.
