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.
MAIN Health Diseases Lyme Disease. Lyme disease (sometimes mistakenly referred to as lime disease) is a disease carried by deer ticks which was first identified and diagnosed in Lyme, Connecticut. It sometimes produces a well-known bull's eye rash around the tick bite - but not always. It can be effectively treated with antibiotics in the early stages. However, if left untreated Lyme disease may result in a myriad of more serious symptoms.
