FIG 4. The nasal carrier strain of SA expresses a greater number of adhesion/ binding proteins in its exoproteome than its non-carrier counterpart.
A comparison of SA exoproteomes using iTRAQ has revealed that (A) the nasal carrier strain of SA (D30) expresses a different repertoire of proteins than (B) a genetically similar non-carrier strain (930918-3). (C) Percentage of proteins that were significantly up-regulated in that category in comparison to the other tested strain. The carrier strain of SA contains a greater proportion of proteins related to binding and adhesion but less stress proteins. Proteins were identified with high confidence (p <0.05) in three independent experiments (N=3).
