In early July, 1863, troops from General Robert E. Leeâs Army of Northern Virginia (the Confederates) met up with a patrol of Union cavalry on the outskirts of Gettysburg, Pennsylvania. Over the next three days, this encounter grew into a turning point of the Civil War.
In the South, lone star ticks (Amblyomma americanum) can also transmit Lyme disease or a closely related illness. Ticks have four life stages: egg, larva, nymph and adult. In each stage after hatching, they suck blood from animals like mice, squirrels, birds and deer.
Lyme condition is dued to the spirochete, Borrelia burgdorferi, and also is transferred by ticks. Lyme disease caused by the spirochete Borrelia burgdorferi and transmitted by vector Ixodes scapular, is the most commonly reported vector-borne illness in the United States.
