At the start of the “Tick Week”, the Netherlands National Institute for Public Health and the Environment (RIVM) and Wageningen University are commencing a large-scale study to discover whether preventive use of antibiotics can stop Lyme disease developing after a tick bite. Of the more than 3400 ticks that were sent to RIVM via Tekenradar.nl (Tick…
Sultan SZ, Manne A, Stewart PE, Bestor A, Rosa PA, Charon NW, Motaleb MA. Infection and Immunity, online before print, 2013 Mar 25. AbstractThe Lyme disease spirochete, Borrelia burgdorferi, exists in a zoonotic cycle involving an arthropod tick and mammalian host. Dissemination of the organism within and between these hosts depends upon the spirochete’s ability…

Mar. 21, 2013 – Scientists have confirmed that the pathogen that causes Lyme Disease — unlike any other known organism — can exist without iron, a metal that all other life needs to make proteins and enzymes. Instead of iron, the bacteria substitute manganese to make an essential enzyme, thus eluding immune system defenses that…
Mar. 20, 2013 – More than three quarters of new, emerging or re-emerging human diseases are caused by pathogens from animals, according to the World Health Organization. But a widely accepted theory of risk reduction for these pathogens — one of the most important ideas in disease ecology — is likely wrong, according to a…
Objective: A structured clinical interview is proposed to assist in the overall clinical assessment when late state Lyme disease is suspected. Method: From a combination of clinical experience, journal review, and discussion with colleagues, a structured interview was developed. Information from patients with late stage neuropsychiatric Lyme disease (NPLD) was entered into a database to…

DOI: 10.2340/00015555-1549 Abstract: Case definitions for European Lyme disease have been published. However, multiple erythema migrans may pose a diagnostic challenge. Therefore, we retrospectively reviewed the clinical and serological findings and response to therapy in a cohort of consecutive 54 patients with PCR-confirmed erythema migrans, referred to a university dermatology clinic. The proportion of patients…
Black-legged ticks are already notorious bad guys known for spreading Lyme disease. Now the nasty little creatures are making people sick by spreading a new and little-known bacteria similar to the germ that causes Lyme disease. There have been no reports of north state residents being sickened by the tick’s bite, even though the Borrelia…
Authors: Tijsse-Klasen E, Pandak N, Hengeveld P, Takumi K, Koopmans MP and Sprong H Citation: Parasit Vectors 2013(Jan); 6(1): 23. “Conclusion This indicates that only a small subset of B. burgdorferi sl carried by ticks in the wild actually cause EM. Other genotypes either may be apathogenic for humans or may cause Lyme borreliosis without…
For several years now it has been known that spirochetal bacteria have been identified in the brains of Alzheimer’s disease patients and that inflamation plays a significant role. Infectious organisims have long been thought to be a cause or trigger of Alzheimer’s disease, and Borrelia have been implicated along with other spirochetal bacteria. Here is a quote…
Ogden, et al Abstract The genetic diversity of Borrelia burgdorferi sensu stricto, the agent of Lyme disease in North America, has consequences for the performance of serological diagnostic tests and disease severity. To investigate B. burgdorferi diversity in Canada, where Lyme disease is emerging, bacterial DNA in 309 infected adult Ixodes scapularis ticks collected in…
