Deciphering the genetic basis of Moraxella catarrhalis complement resistance: Gene expression analysis of Moraxella catarrhalis BBH18 upon exposure to normal human serum.

ABSTRACT: The complement system is an important part of the innate defense against invading pathogens. The ability to resist complement-mediated killing is considered to be an important virulence trait for the human-restricted respiratory tract pathogen M. catarrhalis, as most disease-associated M. catarrhalis isolates are complement-resistant. Here we studied the molecular basis of M. catarrhalis complement-resistance by transcriptome profiling upon exposure to 10% normal human serum (NHS). After 1h exposure of M. catarrhalis BBH18 to 10% NHS (n = 5) or the NHS dilution buffer alone (control, n = 5), total RNA was isolated and labeled cDNA was generated according to standard Nimblegen gene expression array protocols and hybridized to 4x72K Nimblegen M. catarrhalis expression arrays for read-out.
