Haemophilus influenzaeis a Gram‐negative pathogen colonizing the upper respiratory tract mucosa.H. influenzaeis one of several human‐restricted bacteria, which bind to carcinoembryonic antigen‐related cell adhesion molecules (CEACAMs) on the epithelium leading to bacterial uptake by the eukaryotic cells. Adhesion to CEACAMs is thought to be mediated by theH. influenzaeouter membrane protein (OMP) P5. However, CEACAMs still bound toH. influenzaelacking OMP P5 expression, and soluble CEACAM receptor ectodomains failed to bind to OMP P5, when heterologously expressed inEscherichia coli. Screening of a panel ofH. influenzaeOMP mutants revealed that lack of OMP P1 completely abrogated CEACAM binding and supressed CEACAM‐mediated engulfment ofH. influenzaeby epithelial cells. Moreover, ectopic expression of OMP P1 inE. coliwas sufficient to induce CEACAM binding and to promote attachment to and internalization into CEACAM‐expressing cells. Interestingly, OMP P1 selectively recognizes human CEACAMs, but not homologs from other mammals and this binding preference is preserved upon expression inE. coli. Together, our data identify OMP P1 as thebona fideCEACAM‐binding invasin ofH. influenzae. This is the first report providing evidence for an involvement of the major OMP P1 ofH. influenzaein pathogenesis.
