Depending on the suspected stage of the disease and the reason for testing, other tests that may be used include the complement fixation test (CFT), which identifies antibodies in a horse’s blood serum; the immunofluorescence assay, which uses fluorescent substances to detect antibodies bound to specific antigens; and polymerase chain reaction (PCR), which uses DNA amplification to detect the presence of organisms.

The ticks undergo three stages in their life cycle---larvae, nymphs and adults---and they must take a blood meal at each stage to pass to the next and then to lay eggs. “When the spirochetes get into a mouse, they basically swim through the skin and infect the entire body surface of the mouse because it’s so small.
