BACKGROUND: Various genospecies of Borrelia burgdorferi sensu lato (s.l.) have been identified from patients and animals worldwide. Genospecies-related dissemination of disease has been reported. The present study aimed to elucidate the pathogenicity of infections caused by B. garinii SZ isolated in China. B. burgdorferi B31 and B. afzelii BO23 were used for comparison. METHODS: Spirochete…

DOI: 10.4330/wjc.v5.i5.148 Although Lyme carditis is relatively rare within 4-6 wk of exposure, it can uncommonly present as the first sign of disseminated Lyme disease. Here we present 17 year…
Laboratory Investigation , (24 June 2013) | doi :10.1038/labinvest.2013.81 Denise M Imai, Sunlian Feng, Emir Hodzic and Stephen W Barthold Abstract The etiologic agent of Lyme disease, Borrelia burgdorferi, localizes preferentially in the extracellular matrix during persistence. In chronically infected laboratory mice, there is a direct association between B. burgdorferi and the proteoglycan decorin, which…
Two Hamilton-area women are among the growing number of Canadians with Lyme disease paying tens of thousands of dollars to get antibiotics in the United States because of a rift in the medical community over how to diagnose and treat the infection. “It’s a very controversial topic,” said Dr. Michael Gardam, director of infection prevention…
Caesar JJ, Johnson S, Kraiczy P, Lea SM. Source Sir William Dunn School of Pathology, University of Oxford, South Parks Road, Oxford OX1 3RE, England Abstract Borrelia burgdorferi is a spirochete responsible for Lyme disease, the most commonly occurring vector-borne disease in Europe and North America. The bacterium utilizes a set of proteins, termed complement…
Albertans have been asked to keep their eyes peeled for a little black bug over the next few months, one that likes to hitch a ride on your canine companion. The Alberta government has recently expanded its tick surveillance program, asking individuals to submit ticks they find to the nearest participating environmental public health office,…

Mar. 26, 2013 – Early diagnosis is critical in treating Lyme disease. However, nearly one quarter of Lyme disease patients are initially misdiagnosed because currently available serological tests have poor sensitivity and specificity during the early stages of infection. Misdiagnosed patients may go untreated and thus progress to late-stage Lyme disease, where they face longer…

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…
