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.
Only deer ticks can carry the bacterium that causes Lyme disease. They can also carry the germs that cause babesiosis and human granulocytic anaplasmosis. Young deer ticks, called nymphs, are brown and the size of poppy seeds. Adult female deer ticks are red and black, while males are black.
