Within their cell envelope bacteria of the genus Aeromonas have numerous components that help them colonize and survive within diverse environments. Both polar and lateral flagella help in the initial colonization process, with polar flagella being required in liquid surroundings and lateral flagella for the migration across and interaction with surfaces. Glycosylation of the polar flagellar filament is essential for its function, however the full biological role for this is not yet understood. Following the initial interaction with a surface through flagellar mediated motility, filamentous and non-filamentous adherence factors are employed, with the MSHA type IV pilus system playing a major role. However, in non-filamentous strains a number of outer membrane proteins have been proposed to be important in the adherence process. Following colonization, more invasive isolates of the aeromonads that are frequently isolated from cases of bacteraemia or wound infections are able to employ a series of other cell envelope factors that protect them against the host's immune response. These factors include lipopolysaccharide, capsule and the S-layer read more ...
