[Isolation of infectious agent of extrapulmonary tuberculosis by different microbiological methods].

Microbiological research of 59 patients with extrapulmonary localization tuberculosis was conducted for exposition of tuberculosis mycobacterium. It was determined that the method of microscopy of smear painted by Ziel-Nilsen with preliminary treatment of pathological material in the way of "enrichment" using sodium bicarbonate gives more effective result, than the method of direct microscopy of smear painted according to Ziel-Nilsen. It indicates the possibility to use this method for early diagnostics of extrapulmonary tuberculosis, for exposing mycobacteria at its urinary-sexual location.
