[Immunohistochemical study in the diagnosis of tuberculosis].

The comparative analysis of the immunohistochemical method and Ziehl-Neelsen staining was used to search for a new highly sensitivity procedure for diagnosing tuberculosis. With both methods, mycobacteria tuberculosis were detected in 10 cases of fibrocavernous pulmonary tuberculosis, 1 case of general tuberculosis, and 10 cases of disseminated lung lesion (sarcoidosis?). The improved immunohistochemical option using Mycobacterium tuberculosis antibodies (clone 1.1/3/1) have shown AEC and appeared to be the most sensitive than the Ziehl-Neelsen staining and may be therefore recommended for the diagnosis of tuberculosis.
