  2. b Spn9802+ was considered as S. pneumoniae+; P6+ was considered as H. influenzae+.
  3. Results of reference tests and qmPCR for Streptococcus pneumoniae (Spn) and Haemophilus influenzae (Hi) applied to bronchoalveolar lavage (BAL) samples in 156 patients with lower respiratory tract infection (A) and in 31 control patients (B).
