Abstract: A composition including a purified lipid cell-wall component or analog or derivative thereof and a suitable pharmaceutical carrier, medium, excipient or adjuvant is described. The composition is useful in prophylactic and therapeutic methods of treating a microbial infection in a subject, typically a mycobacterial infection such as tuberculosis, and immune disorders, inflammatory conditions and allergies in a subject, typically autoimmune diseases. It is also useful in diagnostic methods. The purified lipid cell-wall component is typically a purified mycolic acid or a mixture of purified mycolic acids from a bacterium which produces mycolic acids. The bacterium is from Mycobacterium, Corynebacterium, Nicardia or Rhodococcus.

Abstract: The invention relates to a diagnostic test for the detection and identification of Mycobacterium species in biological specimens of human and animal origin. The test is based on the immunological detection of one or more antigens originating from Mycobacterium. To enable the detection of an antibody-antigen reaction, the antibodies specific for these antigens can be labelled with an enzyme or fluorescent dye or attached to latex particles or any other suitable label. The diagnostic test may be in a form of ELISA and may or may not require concentration of the Mycobacterium antigens prior to the actual test.

Abstract: A method of purifying mycolic acids, salts thereof or derivatives thereof. The method involves a) providing a mixture including the mycolic acids, salts thereof or derivatives thereof and contaminants; b) dissolving the mixture in a bi-phasic solvent to form a dissolved mixture including the mycolic acids, salts thereof or derivatives thereof and contaminants; c) purifying the mycolic acids, salts thereof or derivatives thereof by subjecting the dissolved mixture to countercurrent distribution separation involving a sufficient number of cycles to separate the mycolic acids, salts thereof or derivatives thereof from the contaminants; and d) removing the separated, purified mycolic acids, salts thereof or derivatives thereof from the bi-phasic solvent. Residual impurities may be extracted from the removed mycolic acids, salts thereof or derivatives thereof with acetone.
