Abstract Public health recommendations for Lyme disease prevention generally include daily tick checks and prompt removal of attached ticks as a means of decreasing the risk of acquiring Lyme disease in highly endemic regions. In the current study, we determined whether crushing nymphal ticks during removal with forceps increased the risk of B. burgdorferi transmission, what degree of protection from transmission of B. burgdorferi was provided by removal of nymphal Ixodes scapularis Say at… 

Transmission of the Lyme Disease Spirochete Borrelia mayonii in Relation to Duration of Attachment by Nymphal Ixodes scapularis (Acari: Ixodidae)

The duration of attachment of a single infected nymphal I. scapularis tick required for transmission of B. mayonii spirochetes appears to be similar to that for B. burgdorferi: transmission is minimal for the first 24 h of attachment, rare up to 48 h, but then increases distinctly by 72 h postattachment.

A recombinant outer surface protein A (OspA) vaccine was approximately 80% effective in clinical trials in the United States, and a single 200 mg dose of doxycycline given within 72 hours of an I. scapularis tick bite, was shown to be 87% effective.

Critical Evaluation of the Linkage Between Tick-Based Risk Measures and the Occurrence of Lyme Disease Cases

The linkage between abundance of host-seeking B. burgdorferi-infected nymphs and Lyme disease occurrence is strong at community or county scales but weak at the fine spatial scale of residential properties, and there is a need for improved risk assessment methodology for residential properties that accounts for both the abundance of infected nymphS and the likelihood of human–tick contact.

Lyme borreliosis (Lyme disease): molecular and cellular pathobiology and prospects for prevention, diagnosis and treatment.

The understanding of how B. burgdorferi survives in the environment and interacts with human and mammalian hosts has improved, however, further advances in prevention and therapy depend on continued investigation of the ecological risks and improved understanding of the pathobiology of this obligate bacterial parasite.

Seroprevalence and Attempted Transmission of Anaplasma phagocytophilum and Borrelia burgdorferi from Naturally Infected Ticks to Cats

Results demonstrate that natural infection of A. phagocytophilum in cats is uncommon and methods used in the study to determine transmission times could be of value in determining times necessary for vector-mediated transmission of agents.

Prevention of Lyme Disease: Promising Research or Sisyphean Task?

Recent data indicate that a broadly effective vaccine against Borrelia burgdorferi sensu lato will to be composed of a mixture of several antigens or multiple epitopes.

Review of methods to prevent and reduce the risk of Lyme disease.

There is a need for new tools to help reduce the risk of Lyme disease to Canadians and existing interventions for prevention of tick bites and Lyme disease are not enough.



Effect of tick removal on transmission of Borrelia burgdorferi and Ehrlichia phagocytophila by Ixodes scapularis nymphs.

Infected I. scapularis nymphs transmitted E. phagocytophila within 24 h in 2 of 3 attempts, which indicates that daily tick removal may not be adequate to prevent human infection with this agent.

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

A single 200-mg dose of doxycycline given within 72 hours after an I. scapularis tick bite can prevent the development of Lyme disease.

Duration of tick attachment as a predictor of the risk of Lyme disease in an area in which Lyme disease is endemic.

Tick identification and measurement of engorgement can be used to identify a small, high-risk subset of persons who may benefit from antibiotic prophylaxis.

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

Seasonal and annual relations between tick densities and patients diagnosed with erythema migrans, the rash associated with early Lyme disease, suggest that annual fluctuations in Lyme disease case numbers are largely due to natural changes in tick abundance and, therefore, that control of nymphal I. scapularis should be a major component of Lyme disease prevention efforts.

Pathophysiology of the Lyme disease spirochete, Borrelia burgdorferi, in ixodid ticks.

While ticks of the genus Ixodes were once thought to be the only vectors, it now appears that other genera, and possibly other hematophagous arthropods, may also be involved.

Fine structural evidence for the penetration of the Lyme disease spirochete Borrelia burgdorferi through the gut and salivary tissues of Ixodes dammini

A detailed electron microscopic study spanning the period of nymphal attachment to the host to determine whether B. burgdorferi invades the salivary acini and ducts of Lyme disease spirochete Borrelia burgdorFERi is employed.

Prevention of Lyme disease after tick bites. A cost-effectiveness analysis.

Empirical treatment of patients with tick bites is indicated when the probability of B. burgdorferi infection after a bite is 0.036 or higher, and this treatment may be preferred when the likelihood of infection ranges from 0.01 to 0.035.

Dissemination and salivary delivery of Lyme disease spirochetes in vector ticks (Acari: Ixodidae).

It is concluded that contact between spirocheteinfected ticks and a host provides the stimulus that ultimately results in dissemination of infection and delivery via saliva, which appears to be the route of Lyme disease transmission in nature.

Temporal Changes in Outer Surface Proteins A and C of the Lyme Disease-Associated Spirochete, Borrelia burgdorferi, during the Chain of Infection in Ticks and Mice

The temporal synthesis of OspC by spirochetes only in feeding ticks that were infected prior to the blood meal suggests that this surface protein is involved in transmission from tick to mammal but not from mammal to tick.

A review of Rocky Mountain spotted fever (tick-borne typhus), its agent, and its tick vectors in the United States.

Its changing status since the beginning of this century is reviewed, and the various factors responsible for the recent increase in disease incidence, which in 1974 reached record proportions, are discussed.
