This could be due to the difficulty in microbiological confirmation in this age group. In this study, we aimed to assess the utility of a real-time multiplex PCR for diagnosis of respiratory pathogens in children with pulmonary TB.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      A total of 185 respiratory samples [bronchoalveolar lavage (15), gastric aspirates (98), induced sputum (21), and sputum (51)] from children aged 3\u201312 years, attending tertiary care hospitals, Chennai, India, were included in the study.

Among patients with negative MTB test results (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u2009165), 145 (87%) tested positive for one or more than one bacterial or fungal pathogens.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The results suggest that tuberculosis could coexist with other respiratory pathogens causing pneumonia.
