Is Borrelia bacteria or virus?

Lyme disease is the most common vector-borne disease in the United States. Lyme disease is caused by the bacterium Borrelia burgdorferi and rarely, Borrelia mayonii. It is transmitted to humans through the bite of infected blacklegged ticks.

Where is Borrelia found?

The disease can be found mainly in Europe, North America and temperate Asia. Typical symptoms include fever, headache, fatigue, and a characteristic skin rash called erythema migrans. This rash occurs in approximately 60–80% of infected persons and begins at the site of a tick bite after a delay of 3–30 days.

Is Borrelia a bacteria?

Borrelia mayonii are a type of bacteria recently found in North America that can cause Lyme disease.

Is Borrelia a parasite?

The spirochete Borrelia burgdorferi is a tick-borne obligate parasite whose normal reservoir is a variety of small mammals [1]. Whereas infection of these natural hosts does not lead to disease, infection of humans can result in Lyme disease, as a consequence of the human immunopathological response to B.

Is Borrelia Gram positive or negative?

What is the size of Borrelia?

burgdorferi cells are long in length and thin in diameter with dimensions of 10–20 µm and approximately 0.3 µm, respectively.
