Objective To analyze influence mycobacterium tuberculosis sputum culture and heat-proof rifabutin antimicrobial susceptibility test results and related factors. Methods To the centers for disease control and prevention of Huainan tuberculosis clinic into the program to treat 227 sputum smear-positive patients in the sputum culture and heat-proof rifabutin of antimicrobial susceptibility test. Results Among 227 patients sputum culture positive 220 cases, accounting for 96. 9%, sputum culture-negative 2 cases, accounting for 0. 9%, pollution, 5 cases of 2. 2%. Resistance rifabutin antimicrobial susceptibility test, a new patient resistance ratio for 10.4%, early cure loser for 37. 5%, concomitant person for 28.9%. Conclusion The mycobacterium tuberculosis in the process of cultivation should be strictly according to the requirements of collecting, processing, specimen vaccination, preservation and observation.
