Using a pin as a reference tool, this photograph depicts a dorsal view of four Gulf Coast ticks (Amblyomma maculatum). From left to right, this group of four included a very young nymph, and older nymph, and adult male, and at far right, an adult female. Note that the head of the pin measures just under 2mm in diameter, while its full length measures 22mm. This tick species is a known vector for Rickettsial organisms, Rickettsia parkeri, and Ehrlichia ruminantium, formerly Cowdria ruminantium. R. parkeri is a member of the spotted fever group of rickettsial diseases affecting humans, while E. ruminantium causes åÒheartwater diseaseåÓ, an infectious, noncontagious, tick-borne disease of domestic and wild ruminants, including cattle, sheep, goats, antelope, and buffalo.
