Bacteriophage in the Ixodes dammini spirochete, etiological agent of Lyme disease.
نویسندگان
چکیده
A bacteriophage with a B-3 morphology was detected by electron microscopy in a spirochete isolated from the tick Ixodes dammini. It has a 40- to 50-nm elongated head and a tail 50 to 70 nm in length. It appears devoid of collars or kite-tail structure. The spirochete has been identified as the causative agent of Lyme disease.

Lyme disease: a selective medium for isolation of the suspected etiological agent, a spirochete.
A simple procedure with a new selective culture medium for the isolation of the suspected etiological agent of Lyme disease from ticks is described. Live ticks (Ixodes dammini) were ground with a mortar and pestle, and the suspensions were inoculated into a selective and nonselective medium. The selective medium, which contained kanamycin and 5-fluorouracil, yielded positive spirochete cultures...
متن کاملAntibodies of patients with Lyme disease to components of the Ixodes dammini spirochete.
Lyme disease is an inflammatory disorder of skin, joints, nervous system, and heart. The disease is associated with a preceding tick bite and is ameliorated by penicillin treatment. A spirochete (IDS) isolated from Ixodes dammini ticks has been implicated as the etiologic agent of Lyme disease. We examined the antibody responses of Lyme disease patients to IDS lysate components in order to furt...

A treponema-like spirochete was detected in and isolated from adult Ixodes dammini, the incriminated tick vector of Lyme disease. Causally related to the spirochetes may be long-lasting cutaneous lesions that appeared on New Zealand White rabbits 10 to 12 weeks after infected ticks fed on them. Samples of serum from patients with Lyme disease were shown by indirect immunofluorescence to contain...

Spirochetes and their vectors and reservoirs were studied in a Lyme disease focus in East Haddam, Connecticut, from mid-May through September 1983. Ixodes dammini subadults were comparable in number on white-footed mice (Peromyscus leucopus) (means = 2.9 +/- 3.6 SD) to those on 27 different species of birds (means = 2.3 +/- 4.2 SD) representing 11 families within the order Passeriformes. Less c...

The prevalence of the Ixodes dammini spirochete (IDS) in white-tailed deer (Odocoileus virginianus) and white-footed mice (Peromyscus leucopus) was studied on the eastern end of Long Island, New York. Both species commonly occur in a variety of habitats, are preferred hosts of Ixodes dammini, and can harbor the spirochetes in the blood. Each animal was examined for spirochetemia, tick infestati...
