Regions important for the adhesin activity of Moraxella catarrhalis Hag.

BMC microbiology - 3 Jul 2007

Bullard Brian, Lipski Serena, Lafontaine Eric R

Abstract excerpt

BACKGROUND: The Moraxella catarrhalis Hag protein, an Oca autotransporter adhesin, has previously been shown to be important for adherence of this respiratory tract pathogen to human middle ear and A549 lung cells. RESULTS: The present study demonstrates that adherence of M. catarrhalis isogenic hag mutant strains to the human epithelial cell lines Chang (conjunctival) and NCIH292 (lung) is reduced by 50-93%....
