Methods: This was a cross-sectional study. A total of 275 patients were included in the study. Adults aged 20 years or older (<80 years), diabetic patients and non-diabetic patients with community acquired pneumonia were included in the study. Sputum and blood culture analysis was done. Results: The prevalence of diabetes was found to be in 37.1% patients. AFB was positive among 71.1% diabetic patients and in 28.9% among non-diabetic patients. Culture was positive among 78.2% diabetic patients and in 21.9% among non-diabetic patients. Entero Aeroganes was among 85.7% diabetic patients and among 14.3% non-diabetic patients on sputum microscopy. Streptococci was in 81.8% diabetic patients and in 18.2% non-diabetic patients on sputum microscopy. Klebsiella pneumonia was in all the diabetic patients on blood culture. Haemophilus influenza was in 90% diabetic patients and in 10% non-diabetic patients on blood culture. Multilobe chest X-ray finding was in 37.5% diabetic patients and in 62.5% of non-diabetic patients. Conclusion: In patients with pneumonia, diabetes mellitus is associated with microbial etiology and multilobe involvement. This study suggests that the adverse outcome is more attributable to the underlying circumstances of patients than to uncommon microbiological findings.
