Detection of outer Membrane Proteins Moraxella catarrhalis Isolated from Infections Respiratory System by Electrophoresis Technique

The study was conducted for the detection of outer membrane proteins of Moraxella catarrhalis strains MD-1, MB-16, MC-10, MD-181, MA-68, isolated from infection respiratory system. OMPs were separated by electrophoresis technique. SDS-PAGE revealed that those strais were differences in the bacteril outer membrane proteins regarding membrane of proteins bands (4-10) and molecular weight (M-W) (20-140) kda. These proteins were identified as virulence factors of Moraxella catarrhalis which caused infections for human respiratory system.
