OBJECTIVE: Pneumonia is still listed as the main health problem on children in developing countries. Pneumonia is the main reason in morbidity and mortality in children below 5 years old. The main cause of pneumonia is microorganisms such as bacteria or virus. In developing countries, pneumonia in children was mainly caused by bacteria. In general, there is a significant correlation between the age and the microorganism causing pneumonia. This correlation can help to predict the cause of pneumonia and to design the therapy. The purpose of this study was to determine the profile of throat swab culture in children at the hospital Prof. Dr. R.D. Kandou, Manado.
METHOD: Descriptife-Retrospective in 112 patients. The subjects of this study were all children aged 1 month and 18 years diagnosed with bronchopneumonia who were hospitalized in the pediatric ward in the years 2017-208 based on the criteria and rating system of IDAI.
RESULT: Bronchopneumonia in boys (56.25%), compared with girls (43.75%). Groups under 5 years old (89.29%), 5 – 10 years (3.57%), and more than  >10 year (7.14%). Swab throat results of Streptococcus pneumoniae (38,39%), E.colli (16.96%), Staphylococcus Aureus (15,18%), Staphylococcus epidermidis (12,5%), Klebsiella Pneumoniae (8,04%), proteus Vulgaris (6,25%), others (2.68 %). There was a significant correlation between Proteus Vulgaris, Streptococcus pneumoniae and length of stay (p= 0,039), Streptocccus pneumoniae, Staphylococcus epidermidis and length of stay (p=0,012). There was no significant correlation between age of children and swab throat result, gender and swab throat result. 
CONCLUSION: The most common patients were boys (56,25%), the age group under 5 years (89.29%). The results of most throat swabs were streptococcus pneumoniae (38,39%). There was a significant correlation between Proteus Vulgaris, Streptococcus pneumoniae and length of stay, Streptocccus pneumoniae, Staphylococcus epidermidis and length of stay.
