Gasmi and colleagues found that you cannot always rely on the testing of engorged ticks to help determine possible exposure to Borrelia burgdorferi (Bb), the causative agent of Lyme disease.

    Dear CanLyme,

    Please tell me how I can obtain 50 copies of the CanLyme wallet card, “Bitten by a Tick?” This card measures 2 1/4″ x 3 1/2″ (or, 5 3/4 cm x 8 3/4 cm). On one side are instructions for removing an attached tick, and on the other are actual size pictures of larval, nymph and adult black legged ticks , plus ways to reduce your exposure to ticks, and what you should ask your doctor, about ticks and Lyme disease. Thank you,
