Antigens of Mycobacterium Tuberculosis Recognized by Antibodies During Incipient, Subclinical Tuberculosis

Clin Diagn Lab Immunol. 2005 Feb;12(2):354-8. doi: 10.1128/CDLI.12.2.354-358.2005.


Serum samples obtained from human immunodeficiency virus (HIV)-infected tuberculosis (TB) patients months prior to clinical TB were used to delineate the profile of Mycobacterium tuberculosis culture filtrate proteins recognized during subclinical TB. A subset of approximately 12 antigens was recognized by antibodies in these serum samples. Antibodies to two of these antigens (81 [88]-kDa malate synthase [GlcB] and MPT51) were present in serum samples obtained during incipient subclinical TB in 19 (approximately 90%) of the 21 HIV-infected TB patients tested. These antigens will be useful for devising diagnostic tests that can identify HIV-positive individuals who are at a high risk for developing clinical TB.
