Introduction: Community acquired pneumonia (CAP) can be caused by different microorganisms. In Latin America the main cause is Streptococcus pneumoniae isolated in about 35-40% of cases. Objectives: To describe the characteristics of patients admitted with diagnosis of CAP at Fundación Santa Fe de Bogotá during a 6 years period, the etiological agents isolated and the pattern of antibiotic susceptibility in the most frequent microorganisms. Materials and methods: Retrospective descriptive study; all patients older than 16 years admitted with diagnosis of CAP were included. Demographic and clinical variables, diagnostic tests to evaluate etiology and the microorganisms isolated were reviewed. Results: At least one microorganism was isolated in 130 patients, being the most common Streptococcus pneumoniae , Haemophilus influenzae and Staphylococcus aureus . We found higher frequency of atypical microorganisms in patients under 65 years and without comorbidities, while enteric gram-negative rods were more frequent in patients with comorbidities or older than 65 years. Discussion: Our most common etiologies are similar to those reported in other series. Special attention is drawn to Staphylococcus aureus as one of the major etiologies and the presence of MRSA. It is important to know the local etiology to adjust guidelines according to the isolated microorganisms, antibiotics susceptibility and availability of resources
