Description
Summary:Goal: to define frequency of detection of non-tuberculous mycobacterioses in Orenburg Region and to study the morphology of the autopsy samples of the patients suffering from HIV infection and non-tuberculous mycobacteriosis.Materials and methods. 7488 mycobacterial cultures were analyzed in order to differentiate non-tuberculous mycobacteria and to identify their species by molecular genetic methods. Post mortem diagnostics was performed with morphological description of generalized forms of mycobacterioses caused by M. avium.Results. The analysis showed that species of Mycobacterium tuberculosis complex significantly prevailed (98.9%) in Orenburg Region. The following non-tuberculous mycobacteria were found in HIV negative patients: M. avium complex, M. xenopi, M. gordonae. M. avium was the most common in HIV positive patients (75%). Non-tuberculous mycobacteriosis possesses a specific diagnostic feature i.e. detection of non-caseous granulomas, consisting of histiocytes and "foamy" macrophages, containing large number of acid-fast mycobacteria in cytoplasm. Diffusive fibrosis of macrophage-histiocyte granulomas and sclerosis of tissue in perifocal area of inflammation are the typical features of it.
