title: [Culture of mycobacterium tuberculosis of gastric juice collected through different ways in diagnosis of pulmonary tuberculosis in children].
abstract: OBJECTIVE
  To explore the value of culture of Mycobacterium tuberculosis through gastric juice specimens in diagnosis of patients with pulmonary tuberculosis in children.
  
  
  METHODS
  Sputum, early morning vomited gastric juice (MVG), the other time vomited gastric juice (OVG) and early morning gastric lavage (MGL) were collected from 46 children with suspected pulmonary tuberculosis. All the specimens were processed to culture for Mycobacterium tuberculosis using pyruvate media, and the results were compared.
  
  
  RESULTS
  Of the 46 cases, Mycobacterium tuberculosis was found in 4 sputum samples (9%), 15 MGL samples (33%), 12 MVG samples (26%) and 2 OVG samples (4%).
  
  
  CONCLUSIONS
  Collecting gastric juice through different methods for culture of Mycobacterium tuberculosis is specific for diagnosis of paediatric pulmonary tuberculosis.
