The persistence of Borrelia burgdorferi in six patients is described. Borrelia burgdorferi has been cultivated from iris biopsy, skin biopsy, and cerebrospinal fluid also after antibiotic therapy for Lyme borreliosis. Lyme Serology: IgG antibodies to B. burgdorferi were positive, IgM negative in four patients; in two patients both IgM and IgG were negative. Antibiotic therapy may abrogate the antibody response to the infection as shown by our results. Patients may have subclinical or clinical disease without diagnostic antibody titers. Persistence of B. burgdorferi cannot be excluded when the serum is negative for antibodies against it.

A previous laboratory study using Haemaphysalis longicornis Neumann (Acari: Ixodidae) ticks of North American origin showed that larvae could acquire the Lyme disease spirochete, Borrelia burgdorferi sensu stricto (s.s.) (Spirochaetales: Spirochaetaceae) while feeding to completion on infected mice.

Background: Lyme disease (LD) is caused by and is the most common tickborne disease in the northern hemisphere. Although classical characteristics of LD are well-known, the diagnosis and treatment are often delayed. Laboratory diagnosis by serological testing is recommended for most LD manifestations.

Lyme disease is commonly associated with musculoskeletal features, inflammatory and noninflammatory. The precise pathogenesis of the clinical features of this infection are complex and often multiple. A better understanding of how Borrelia burgdorferi causes these musculoskeletal manifestations is necessary in order to determine the proper treatment and eschew that which is unlikely to work, often associated with toxicities.

The bacterium responsible for Lyme disease, , accumulates high levels of manganese without iron and possesses a polyploid genome, characteristics suggesting potential extreme resistance to radiation. Contrary to expectations, we report that wild-type B31 cells are radiosensitive, with a gamma-radiation survival limit for 10 wild-type cells of <1 kGy. Thus, we explored radiosensitivity through electron paramagnetic resonance (EPR) spectroscopy by quantitating the fraction of Mn present as antioxidant Mn metabolite complexes (H-Mn).
