Infants and children o£ 405 cases with respiratory diseases and 290 cases with non-respiratory diseases who were admitted to pediatric department, Severance hospital from May, 1973 to April, 1975 were performed bacterial cultures from their throat were compared with different state of bacterial flora of both groups. The following results were obtained; 1.Total number of bacteria isolated from respiratory patients and non-respiratory patients, were 637 and 484 respectively. Of these, probable pathogenic bacteria were 110 (17.3%) in respiratory patients and 69 (14. 3%) in non-respiratory patients. These findins showed nearly same culture rate of pathogenic bacteria in both groups. 2.Culture incidence of various bacteria. A. Pathogenic bacteria: Coagulase (+):staphylococci was cultured most commonly (50% of all pathogens), and the next common bacteria was pneumococci (21. S%') in respiratory patients. In non-respiratory patients, coagulase (+) staphylococci was also most commonly cultured (40.6%), and next common pathogen was pneumcocci (24.6%). B.Probable normal flora: Alpha streptococci was cultured most commonly from both respiratory and non-respiratory patients and were 46.5% in the former and 51.3% in the later. The next common organism was non-pathogenic Nesseria in the both groups. The above findings showed that the most common and-the next organism in order of culture rate (%) on the same organisms were nearly same as both respiratory and non-respiratory patients. 3. Monthly distribution of culture incidence of various organisms revealed no significant findings on the both groups. 4.Bacterial sensitivity to several antibiotics showed same rate of sensitivity to same kind of antibiotics on both .respiratory and non-respiratory patients. On the point of view of above findings, we should pay an attention for evaluation of bacterial cultures when we perform the throat cultures from the patient with respiratory diseases for detection of the causative organisms.
