Since M. catarrhalis has been considered a harmless commensal bacterium for a long time, there is relatively little cognition about pathogenicity characteristics and its virulence factors. Generally, the pathogenicity of this bacterium, like other microorganisms, depends on the ability to escape from the host defense mechanisms and binding to cellular and mucus layer, as well ( 4 ).
