The two most important surface lipoproteins of Borrelia burgdorferi (OspA & OspD), which were produced by recombinant technology, were also included in the study.Results: The obtained results showed that 33 of 50 patients who were tested and some of normal controls, had antibodies in their serum against Borrelia protein bands. Fisher’s exact test indicated a significant difference between MS patients and normal controls regarding 43 KDa protein band, which became positive in 7 MS patient but none of our controls. We could not detect positive reaction with Borrelia surface lipoproteins (OspA & OspD) in serum and CSF of any of our patients or normal controls.Conclusion: Considering our results and a lot of similarities between pathogenesis and clinical manifestation of MS and spirochetal lyme disease there are some evidences for spirochetal basis of MS but its confirmation needs further investigations. %U https://www.celljournal.org/article_248713_8314126540a185ce939b58d90477726a.pdf
