Prophylaxis with single-dose doxycycline for the prevention of Lyme disease after an Ixodes scapularis tick bite.]

Article Abstract:

A single dose of the antibiotic doxycycline can prevent Lyme disease in people who have been bitten by the deer tick that transmits the disease. This was the conclusion of a study of 482 people who had been bitten within the previous three days.

Simultaneous human granulocytic ehrlichiosis and Lyme borreliosis

Article Abstract:

The case of a 47-year-old man illustrates that people can be infected with the Lyme disease bacterium and the organism that causes human granulocytic ehrlichiosis at the same time. This can happen because both organisms are transmitted by the deer tick. The man saw a doctor because he had fever, headache, weakness and joint pain. He had been bitten by a tick two months prior to the visit. The rash typical of Lyme disease was present and he was treated with doxycycline. His symptoms resolved shortly thereafter. Polymerase chain reaction (PCR) analysis of blood and skin samples revealed both organisms.

Temporal relation between Ixodes scapularis abundance and risk for Lyme disease associated with erythema migrans

Article Abstract:

Tick control may reduce the risk of Lyme disease. Researchers measured the seasonal fluctuations of Ixodes scapularis by the number of tick bites from Janurary to April, when only adult ticks are active. The characteristic rash for early Lyme disease, erythema migrans, was absent during this period. Nymphal tick bites per year, however, were somewhat associated with the incidence of erythema migrans. Nymphal tick control may effectively prevent Lyme disease.
