<prompt> Which of the following is FALSE regarding mycobacterium?Cell wall has high lipid contentMycolic acids and LAM form waxy coatLack exotoxins or endotoxinsNone of the above  <response>: Of paicular impoance is the presence of long-chain fatty acids called mycolic acids for which the mycobacteria are named and lipoarabinomannan LAM, a lipid polysaccharide complex extending from the plasma membrane to the surface. These elements give the mycobacteria a cell wall with unusually high lipid content more than 60 of the total cell wall mass, which accounts for many of their biologic characteristics. It can be thought of as a waxy coat that makes them hardy, impenetrable, and hydrophobic. Mycobacteria do not produce classic exotoxins or endotoxins. Disease processes are thought to be the result of two related host responses: Delayed-type hypersensitivity DTH Cell-mediated immunity CMI Ref: Ray C.G., Ryan K.J. 2010. Chapter 27. Mycobacteria.
