Objective: To study the pathogen of postoperative infection outbreak in a hospital in Shenzhen.
Methods: According to the Laboratory Science Procedure of Diagnostic Bacteriology in Tuberculosis published by Chinese Antituberculosis Association, Bergey's Manual of Determinative Bacteriology (ninth edition), and the Clinical Bacteriology Examination & Development, 97 wound exudates were cultivated by the traditional bacteriologic method. The strains were identified with three standard strains of M. chelonae subsp. chelonae, M. chelonae subsp. abscessus and M. fortuitum as controls.
Results: 26 fast-acid positive and fast growth nontuberculous mycobacterium were isolated from 97 exudates, then 41 strains including other 15 strains which were collected from the hospital were identified as M. chelonae subsp. abscessus.
