[Abstract]:Objective to evaluate the application value of colloidal gold method and smear morphology in the identification of clinical isolates of Mycobacterium tuberculosis, and to analyze the clinical isolates of non-tuberculous mycobacteria (NTMM). To investigate the clinical isolation rate and distribution of NTM in Fujian Province. Methods 3681 clinical isolates of Mycobacterium tuberculosis were identified by smear morphological characteristics and colloidal gold method of Mycobacterium tuberculosis antigen. The results were compared with the results of traditional PNB method. The identified NTM strains were identified by hsp65- and rpoB-PCR-RFLP. Results the clinical isolation rate of 3681 clinical isolates of Mycobacterium was 11.0. The traditional PNB/TCH identification and culture method was used as the gold standard. The coincidence rate between MTBC and NTM was 98.9, the sensitivity was 98.4%, the specificity was 95.888 / 405, the positive predictive value was 99.97% and the negative predictive value was 91.2%, the coincidence rate of colloidal gold assay of Mycobacterium tuberculosis antigen was 98.22.The sensitivity of colloidal gold assay of Mycobacterium tuberculosis antigen was 98.82% and the sensitivity was 32373276%. The degree is 99.7 / 404 / 405, the positive predictive value is 99.5% and the negative predictive value is 88.4. When both methods were positive, the positive predictive value of MTBCcould be 100.0 and the negative predictive value of NTMand the negative predictive value of both methods were 100.0 and 100.0 respectively. A total of 405 NTM strains were identified and identified by hsp65- and rpoB-PCR-RFLP. Among them, M. intracellulare 173 strains, M. avium 88 strains, M. aviumum 88 strains, M. abscess M. abscessus)55 strain 13.5858, M. Gordon M. gordonae)28 strain 6.91C, M. massiliense subspecies 19 strains 4.69m, M. sporophyllum M. fortuitum)9 2.22th, M. fulvium M. lentiflavum 6 strains, M. aeruginosa M. lentiflavum strain 13.58, M. Gordon M. gordonae)28 strain 6.91, M. massiliense subspecies 19, M. fortuitum)9 2.22th, M. lentiflavumum 6, Mycobacterium abscess M. lentiflavum6, M. aeruginosa M. lentiflavum 6. 1. 48% of Mycobacterium Maxima M. marseillens)5 strain 1.23%, M. szulgai)3 strain 7.41 1, M. Monaco M. saskatchewanense subspecies, 1. 23%, 1. 23%, 1. 48%, 1. 23%, 1. 23%, 1. 48%, 1. 48%, 1. 23%, 1. 23% and 1. 23%. Mycobacterium Seoulenseus, M. shimoidei subspecies and M. triplexus, 2 strains each, 0.49cm, Gordonia bronchialisus, M. chelonaeae, M. Colombia, M. colombiense, M. genavenseus, M. Holstein M. holsaticum, M. kansasiiana, M. bear, M. kumamotonenseus, M. mantenii subspecies, M. Monacenseus, M. septicum (M. septicum) and 1 M.stomatepiae subspecies (M. septicum) of M. Monacenseus each. Conclusion smear morphology and colloidal gold of Mycobacterium tuberculosis antigen are fast, simple and accurate methods for identifying MTBC and NTM. The clinical isolation rate of NTM in Fujian Province from 2009 to 2010 was 11.0%. The main prevalent strain of NTM in Fujian Province was the combination of bird and intracellular mycobacterium (Marc), which accounted for 64.45% of the total.
