Most Viral Host Ranges Are Narrow. The fact that the host range â the group of cell types that a virus can infect â is generally restricted serves as a basis for classifying viruses. A virus that infects only bacteria is called a bacteriophage, or simply a phage.
In 1981, a scientist who was studying Rocky Mountain Spotted Fever (also caused by a tick bite) began to study Lyme disease. This scientist, Willy Burgdorfer, found the connection between the deer tick and the disease. He discovered that a bacterium called a spirochete, carried by ticks, was causing Lyme.The medical community honored Dr. Burgdorferâs discovery in 1982 by naming the spirochete Borrelia burgdorferi.istory of Lyme Disease. Ticks and Lyme disease have been around for thousands of years. In fact, a recent autopsy on a 5,300-year-old mummy indicated the presence of the bacteria which causes Lyme disease.
Lyme disease is caused by bacteria transmitted by the deer tick (Ixodes scapularis) . Lyme disease may cause symptoms affecting the skin, nervous system, heart and/or joints of an individual. Over 98,500 cases have been reported to the New York State Department of Health since Lyme disease became reportable in 1986.yme disease is a bacterial infection caused by the bite of an infected deer tick. Untreated, the disease can cause a number of health problems. Patients treated with antibiotics in the early stage of the infection usually recover rapidly and completely.
