Description:
This photograph depicts a dorsal view of a female 'lone star tick', Amblyomma americanum. An ixodid or 'hard' tick, A. americanum is found through the eastern and south-central states and can transmit disease agents that affect humans, dogs, goats, and white-tailed deer. Representatives from all three of its life stages aggressively bite people in the southern U.S. Lone star ticks transmit Ehrlichia chaffeensis and Ehrlichia ewingii, both of which cause disease. Borrelia lonestari, a pathogen associated with 'Southern tick-associated associated rash illness' (STARI), also infects lone star ticks. Research suggests that up to 10% of the lone star ticks in an endemic area can be infected with any one of these pathogens. These ticks also are infected with a spotted-fever group Rickettsia, 'Rickettsia amblyommii' but it is unknown at this time if this bacterium causes disease.
