People re-infected with Lyme disease may develop strain-specific immunity

Borrelia burgdorferi, spirochete, lyme disease
Have you ever wondered whether an infection with the Lyme disease (LD) spirochete elicits protective immunity? Izac and Marconi addressed that question in a recent study. The authors examined mice infected with clonal populations of spirochetes to determine if broad or strain-specific, bactericidal antibody responses occurred. [1]

Permethrin-treated clothing causes “hot foot” effect in ticks

Several studies have found that wearing permethrin-treated clothing can reduce the risk of tick bites. But very few studies have looked at the behavior of a tick when it comes in contact with permethrin-treated clothing. Does it climb onto the insecticide-soaked textile or avoid it entirely? Does permethrin actually kill ticks?

The best antibiotics to treat Borrelia miyamotoi?

Borrelia miyamotoi may be a disease you have never heard of. But the threat of this tick-borne illness is very real. First described in Japan in 1995, this emerging infectious disease is transmitted by the same blacklegged tick which carries the Lyme disease pathogen. In “Antimicrobial susceptibility of Borrelia miyamotoi,” researchers examine the effectiveness of several antibiotic regimes in the treatment of HTBRF.

Only a minority of children with Lyme disease recall a tick bite

With at least 300,000 new cases of Lyme disease each year in the U.S., an estimated 25% of those involve children. Unfortunately, the prevailing message has been that the majority of people, including children and adolescents, who develop Lyme disease will see either a tick bite or a bull’s eye rash. This just isn’t the case, as a new study by Nigrovic and colleagues demonstrates.

Lyme disease manifests as autoimmune disorder, Sjögren’s syndrome

Lyme disease symptoms can mimic many other illnesses and have been linked to several autoimmune diseases including Sjögren’s syndrome [1], Dermatomyositis [2], and Guillain-Barre syndrome [3]. A case report by Smiyan entitled “Sjögren’s syndrome and lymphadenopathy unraveling the diagnosis of Lyme disease,” reflects the importance of a thorough clinical evaluation.
