Objective This paper tries to observe and study the pathogens in elderly patients with COPD and pulmonary infection. Methods 300 cases of elderly COPD patients with pulmonary infection from November 2016 to October 2017 in the hospital were convenient selected and regarded as the object of this study. The patient sputum specimens for pathogenic bacteria culture and clinical analysis were identified. Results Among 300 elderly patients with COPD and pulmonary infection, sputum samples were cultured in 130 cases with the detection rate of 43.33%. Among them, 139 strains were detected,13 were fungi(9.35%), 8 were Gram-positive bacteria cases(5.75%), Gram-negative bacteria in 118 cases(84.89%). Conclusion Gram-negative bacteria should be the main pathogens in elderly patients with chronic obstructive pulmonary disease and pulmonary infection. Therefore, a merger of antibiotic-resistant fungi and Staphylococcus aureus should be given priority to in combination with Gram-negative bacilli.
