Under a magnification of 400X, this photomicrograph depicts a number of live, newly-discovered. Borrelia mayonii spirochetes, that were in a modified liquid culture of Barbour-Stoenner-Kelly (BSK) medium, while being viewed using a dark field microscopy technique. Note the characteristic corkscrew shape of the spirochetes, and both the 10µm, and 20µm measurement marks indicating the approximate size of these organisms. This image was created using a Zeiss AxioCam. See PHIL 20517, 20518, and 20520, for more images depicting this bacterium.
These Borrelia mayonii bacteria, were extracted from an isolate, which was obtained by culturing the blood of a patient with active bacteremia. B. mayonii had probably been transmitted to the patient by way of the bite of an infected deer tick, Ixodes scapularis. This is the same tick responsible for transmitting Borrelia burgdorferi, known to cause Lyme disease.
