<prompt> Which of the following condition is related with antibodies against phenolic glycolipid PGL-1?M. lepraeM. tuberculosisBorreliaBrucella  <response>: The bacteriums complex cell wall contains large amounts of an M. leprae-specific phenolic glycolipid PGL-1, which is detected in serologic tests. The unique trisaccharide of M. leprae binds to the basal lamina of Schwann cells; this interaction is probably relevant to the fact that M. leprae is the only bacterium to invade peripheral nerves. IgM antibodies to PGL-1 are found in 95 of patients with untreated lepromatous leprosy. Ref: Gelber R.H. 2012. Chapter 166. Leprosy. In D.L. Longo, A.S. Fauci, D.L. Kasper, S.L. Hauser, J.L.
