Background: Chronic obstructive pulmonary disease (COPD) is a well-known, preventable, and curable condition. Frequent respiratory symptoms and a reduction in airflow caused by abnormalities in the airways and/or alveoli are its defining features (1). The prevalence of COPD is 10 % in people over forty years old whereas COPD prevalence in Iraq among adult smokers is 15.1% (2). Infections are the principal source of acute exacerbation of COPD (AECOPD (and these infections are implicated in 40% to 60% of exacerbation cases. Worldwide, a variety of bacteria, such as Pseudomonas aeruginosa, Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis, are recognized to cause AECOPD (3). Aim:  The aim of this work was to identify the main bacterial isolates associated with COPD. Method: This study included 70 patients (46 males and 24 females) suffered from COPD. All these patients were detected through a full medical examination, and chest examination, such as a spirometry.  Sputum samples were collected and processed, followed by performing gram staining and culturing. The main isolates were identified using Vitek II systems. Results: According to results of this study, Pseudomonas aeruginosa was found to be the predominant cause of COPD infections, with Klebsiella pneumonia following closely in frequency. Conclusion: In conclusion, Pseudomonas aeruginosa and Klebsiella pneumonia have been identified as the main bacterial infections associated with COPD.
