Despite having the genetic apparatus, B. miyamotoi typically does not manifest with a relapsing fever. “Although evidence of antigenic variation, which drives the relapsing course of other relapsing fevers due to borrelia has not been demonstrated clinically or in an animal system thus far for B. miyamotoi [2], it has been shown that this species […]

by Daniel J. Cameron, MD MPH Doctors in Bogotá, Colombia, describe an encounter with a 24-year-old American woman whom they eventually diagnosed with Lyme disease seven days after she arrived in the country from Virginia, USA. [1] The woman presented to a Bogotá emergency room with a “popular pruritic lesion in [the] right flank.” The

Doctors described a case of BMD in a previously healthy 63-year-old American man living in Japan. “He reported being bitten by ticks several times while staying with his family at his summer house in the state of Minnesota in the USA from July 25 to August 9, 2013,” according to Oda from the Division of Infectious

The OspA vaccine trial was 78% effective at preventing a culture confirmed erythema migrans rash. But the vaccine was only 48% effective at preventing what the authors referred to as “possible Lyme disease.” “Possible Lyme disease was defined as a flu-like illness (fever, chills, fatigue, headache, joint or muscle aches) with IgM or IgG Western blot

by Daniel J. Cameron, MD MPH The authors found 13% of patients with a spinal tap positive by both cerebrospinal fluid pleocytosis and Borrelia-specific antibodies remained ill for more than 3 months after treatment. Meanwhile, 33% of Lyme neuroborreliosis patients with Borrelia-specific antibodies detected in cerebrospinal fluid and 43% of Lyme neuroborreliosis patients with pleocytosis

Thirty minutes later, he found himself on the bathroom floor, not recalling any premonitory symptoms for syncope. In the following weeks, he experienced a sharp decrement in exercise tolerance,” according to Patel

by Daniel J. Cameron, MD MPH According to the authors, “If uncontrolled in the context of neuroborreliosis, the astrocyte response could lead to long-term injury in the CNS.” Researchers identified changes in gene expression within 48 hours of infecting cultured astrocytes with Borrelia burgdorferi (Bb). “Understanding how these changes are maintained over time will be

by Daniel J. Cameron, MD MPH A 51-year-old man in the United Kingdom was hospitalized with retrosternal, dull chest pain. He had a history of palpitations, dizziness, and sweating and a previous transient ischemic attack.[1] He presented with a heart rate of 180 with right bundle branch block, a superior QRS axis, and signs of

by Daniel J. Cameron, MD MPH According to a 2017 study published in Clinical Infectious Disease, a pronounced TH17 cytokine response may be beneficial in the early stages of Lyme disease. “In these patients, the levels of inflammatory mediators, particularly TH17-associated cytokines, correlated directly with B. burgdorferi IgG antibodies (P<0.02), suggesting a beneficial role for

Questing ticks were collected from grassland, hedges, parks, woodland and woodland edges in Salisbury, an urban area located in Wiltshire, England. Ticks were identified at over 50% of the 25 sites surveyed. Furthermore, investigators reported that the collected ticks carried two pathogens posing a health risk to the public. The “DNA of Borrelia burgdorferi s.l.
