title: [New microbiological Techniques in diagnosis of tuberculosis].
abstract: Microbial spectrum in patients with disorders of the upper respiratory tract consisted mainly of streptococci, staphylococci and pneumococci in 1991-1993, 1994 and later, respectively. Most specific for detection of nontuberculous flora was brushing with protecting agar plugs in combination with transport medium and anaerobic culturing. Direct immunofluorescence allows detection of antigens M. chlamydia in 29.4%, M. pneumoniae in 18.5% of cases. In diagnosis of tuberculosis the following new technologies were introduced: bacterioscopy with previous culturing of the material on liquid culture media followed by biological test and polymerase-chain reaction; determination of drug resistance based on nitrate reductase activity of M. tuberculosis indicating resistance of M. tuberculosis on liquid media in 4-7 days, dense egg media in 8-12 days, usage of Popesku medium enables correction of tuberculosis chemotherapy one month after the test initiation; M. tuberculosis identification using Western blot with monoclonal antibodies in some cases for 7 days.
