The purpose of this work was to determine the frequency of occurrence of S. aureus, H. influenzae, H. parainfluenzae, beta-heamolytic streptococci, Enterohacteriaceae spp. and nonfermenting rods in a group of children suffering from acute successive pharyngitis and tonsillitis. Specimens were taken during three acute occurrences and twice after treatment from first and second acute occurrences. S. aureus was isolated from the throats of 55.1% - 62% of the sick children. H. influenzae and H. parainfluenzae were isolated from about 22% to over 40% of the sick children, beta-haemolytic streptococci were isolated from 10.3% - 16.2% of the sick children and Enterobacteriaceae spp. were isolated from the throats of 6.1%-16.25% of the sick children. Nonfermenting rods were isolated from only one sick child. Two or more possible bacteria) pathogens were isolated from several sick children. Among them S. aureus with H. influenzae or with H. parainfluenzae or with beta-haemolytic streptococci were most often isolated. After treatment of these children, S. aureus, H. influenzae, H. parainfluenzae were more rarely isolated from the throat, and beta-haemolytic streptococci or Enterobactericeae spp. were isolated occasionally. Similarly, after treatment mixed potentially pathogenic bacterial flora were more rarely seen.
