Description
This photograph depicted a dorsal view of an immature, or nymphal, "lone star tick", Amblyomma americanum. Nymphal ticks are much smaller than adult ticks, and people might not notice a nymph until it has been feeding for a few days. Nymphs are, therefore, more likely than adult ticks to transmit diseases to people. An Ixodes or “hard” tick, A. americanus is found through the southeast and south-central states, and has been shown to transmit the spirochete, Borrelia lonestari, the pathogen responsible for causing a Lyme disease-like rash known as “Southern tick-associated associated rash illness” (STARI). Representatives from all three of its life stages aggressively bite people in the southern U.S. Research indicates that live spirochetes are observed in only 1-3% of specimens. Symptoms and DiagnosisPersons who have been bitten by a lone star tick, A. americanum, and who develop a red, expanding rash with central clearing, known as “erythema migrans”, headache or myalgia with fever, should see their physician. The Centers for Disease Control and Prevention (CDC) is interested in obtaining samples from such patients under an Institutional Review Board-approved investigational protocolPrevention and TreatmentPrevention measures similar to those for the Lyme disease vector will reduce your exposure to infected ticks. See Lyme Disease Prevention and Control for information on how to- avoid tick habitats,- reduce tick abundance,- use personal protection equipment, and- check and remove ticks.
