An Analysis on Ordinary Sputum Bacteria Culture Results and Clinical Treatment for 108 Cases with Pulmonary Tuber- culosis

Objective To Investigate the distribution characteristics of drug-resistant pathogenic bacteria, the clinical manifestations and the clinical treatment in lower part of respiratory tract for patients with pulmonary tuberculosis.Methods The deep sputum from patients was collected for bacteria culture, and sensitive tests to antibiotics in Vitro were conducted for positive cultures after the positive bacteria were assured.Results All 125 cases of pathogenic bacterial strains were found in sputum bacteria culture of 108 patients. There were 111 strains of gram-negative(88.8%) and gram-positive cocci 14 (11.2%). The results of drug sensitive test suggested that L-floxaxin had the highest susceptibility, their rate was 60%, and Co-SMZ had the lowest susceptibility rate, only 1%.Conclusion The primary pathogenic bacteria were gram-negative bacilli in lower respiratory tract of pulmonary tuberculosis patients, which may be related to immunodeficiency, antibiotics abuse and treated with antituberculosis drugs.
