patients with tracheostomy had more tracheal cell adherence ( 7.3 +/- 0.4 [ se ] bacteria/cell ) than controls ( 4.8 +/- 0.7 bacteria/cell ; p = 0.008 ) , but patients colonized by pseudomonas species had even more binding ( 9.0 +/- 0.06 bacteria/cell ) than those without this finding ( 5.8 +/- 0.8 bacteria/cell ; p = 0.008 ) .
