Under a magnification of 400X, this photomicrograph depicts a number of newly-discovered. Borrelia mayonii spirochetes, which were killed during the preparation of this image. The glass slide from which this image was been obtained, had been prepared, as a methanol-fixed, Giemsa-stained specimen, and viewed using a bright-field microscopy technique. See PHIL 20517, 20518, and 20519, 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.
