Detection of Borrelia burgdorferi sensu lato by proteomics: a complementary diagnosis tool on erythema migrans biopsies.
Objectives: We have developed targeted proteomics in the context of Lyme borreliosis (LM) as a new direct diagnostic tool for detecting Borrelia proteins in the skin of patients with erythema migrans. If satisfactory, this proteomic technique could be used in addition to culture and/or PCR for disseminated infections where Borrelia detection is essential to demonstrate active infection. In these infections, the diagnosis is indirect and relies mainly on serology.
Methods: We recruited 46 patients with LM and 11 controls and collected two skin biopsies from each patient. One biopsy was used for Borrelia burgdorferi sensu lato PCR and culture and the other one was for targeted mass-spectrometry-based proteomics. Six markers of infection were selected for proteomics: Outer surface protein C (OspC), flagellin, enolase, lipoprotein gi|365823350, decorin binding protein A, and glyceraldehyde-3-phosphate dehydrogenase.
Results: Culturing Borrelia from the biopsies increased the sensitivity of the methods. Among the patients included for analysis, 61% (28 patients), 61% (28), and 46% (21) were detected as positive by proteomics, PCR, and culture, respectively. PCR and proteomics were complementary. OspC and flagellin were the most frequently detected protein markers of infection by proteomics, which in some patients, detected up to nine peptides for the flagellin.
Discussion: It is possible to identify bacterial makers from the skin by proteomics. Our approach can be used to diagnose tick-borne diseases such as LM.
期刊介绍：
Clinical Microbiology and Infection (CMI) is a monthly journal published by the European Society of Clinical Microbiology and Infectious Diseases. It focuses on peer-reviewed papers covering basic and applied research in microbiology, infectious diseases, virology, parasitology, immunology, and epidemiology as they relate to therapy and diagnostics.
