Hulínská D, Krausová M, Janovská D, Rohácová H, Hancil J, Mailer H. Department of Electron Microscopy, National Institute of Public Health, Prague, Czech Republic. Results of studies using direct antigen detection suggest that seronegative Lyme borreliosis is not rare and support the hypothesis that Borrelia antigens can persist in humans. We report three successful cultures from blood out of 30 attempts from 96 Lyme disease patients. The proof of borreliaemia in early or late phases of Lyme disease by immuno-capture electron microscopy has practical importance for subsequent cultivation. The polymerase chain reaction with oligonucleotide sequences directed against 16S rRNA identified two of our blood isolates as Borrelia burgdorferi genospecies III., VS 461 group, and one as Borrelia garinii sp. nov. All of the three isolates were reactive with monoclonal antibody H9724 against flagellin and with antibody against main extracellular protein at 83 kDa. Borrelia garinii had a single predominant protein OspA at 33.5 kDa and reacted with monoclonal antibody H5332 in contrast to two isolates of the VS 461 group with two major proteins OspA and OspB at 32.5 and 35 kDa. We conclude that isolation of spirochetes from the blood might prove successful in clinically selected cases of Lyme borreliosis. Immuno-capture electron microscopy has proved to be a sensitive assay for monitoring and studying Lyme borreliosis.Clin Orthop Relat Res. 1993 Dec;,297:238-41. Chronic septic arthritis caused by Borrelia burgdorferi. Battafarano DF, Combs JA, Enzenauer RJ, Fitzpatrick JE. Department of Medicine, Fitzsimons Army Medical Center, Aurora, Colorado 80045-5001. Chronic arthritis occurs in 10% of Lyme disease patients. A patient had chronic septic Lyme 31arthritis of the knee for seven years despite multiple antibiotic trials and multiple arthroscopic and open synovectomies. Spirochetes were documented in synovium and synovial fluid, SF. Polymerase chain reaction, PCR, analysis of the SF was consistent with Borrelia infection. Persistent infection should be excluded with silver stains and cultures in any patient with chronic monoarticular arthritis and a history of Lyme disease
