In the purulent\/mucopurulent samples, 85.2% showed positive growth on culture compared to 35% of mucoid samples. Cultures grew single pathogens in 108 cases, and 2 grew multiple pathogens; in 127 cases, no pathogenic organisms were isolated. In all, 41 (37.96%) isolates grew Gram-positive and 67 (62.04%) grew Gram-negative organisms. The most effective antibiotic against Gram-negative bacteria was imipenem (50%) and that against Gram-positive bacteria was vancomycin (70.59%). All isolates were resistant to ampicillin.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Sputum culture is a good and simple tool to study the aetiology and complications caused by bacteria in AECOPD.
