title: [Preliminary study on the aerobes distribution of nasal cavity from the healthy children and adults].
abstract: OBJECTIVE
  To study whether there are differences in the bacteria distribution from the nasal cavity of the healthy children, teenagers and adults
  
  
  METHODS
  The cotton swab specimens were taken from the nasal cavity of the healthy children, teenagers and adults for aerobic culture training.
  
  
  RESULTS
  Corynebacterium, coagulase-negative staphylococci, Staphylococcus aureus, Gram-negative Neisseria, alpha-hemolytic streptococcus and gram-negative bacillus with, six species of bacteria in total, were cultivated from the nasal cavity of 40 healthy children. The positive rate of bacterial culture was 80.0%; Corynebacterium, coagulase-negative staphylococci and Staphylococcus aureus were cultivated from the nasal cavity of 40 healthy teenagers and 56 healthy adults with the positive rate of bacterial culture was 90.0% from the healthy teenagers group and was 92.9% from the healthy adults group.
  
  
  CONCLUSIONS
  There were obvious difference between the nasal cavity of the healthy children and adults with no obvious difference between the bacteria distribution from the nasal cavity of healthy teenagers and adults.
