Abstract: The pathogenic bacteria causing infection, first overcomes host innate and adaptive immunity. In order to adapt to the pressure of the surrounding environment, bacteria interact with host with genetic and phenotypic changing constantly to survive. The mechanism of adapting to host pathogen are described, including genetically altered virulence factor reduction strategy, bacterial phenotype changes such as outer membrane protein, lipopolysaccharide and exopolysaccharide, also changes of bacterial resistance, motility and the quorum sensing.

Key words: pathogenic bacteria, adaptation mechanism, virulence down regulation, phenotypic change, quorum sensing
