(B) NHPH adhesins and virulence factors involved in the adhesion mechanism. - "Adhesion of Helicobacter Species to the Human Gastric Mucosa: A Deep Look Into … One of the most important steps during pathogenesis of a bacterium is its attachment to mucosal or other biotic surfaces, such as respiratory, urinary, or gastrointestinal tracts. The attachment to these surfaces in many bacteria has been attributed to adhesins; thus, suggesting their role as a virulence … Visa mer Many pathogenic and non-pathogenic bacteria associate with surfaces, and this is achieved using proteins called adhesins. Bacterial adhesins recognise and attach to target molecules on a surface in a lock and key mechanism, … Visa mer Bacterial adhesins are attached to thin thread-like, one-micron long structures that are called pili or fimbriae. They are rigid structures with a diameter of 2–10 nm. The structure … Visa mer As one of the critical steps in pathogenesis is attachment of a bacteria to a mucosal surface, several vaccines have been developed … Visa mer Two secretary pathways involved in the expression of adhesins on bacterial cell surface are known. These are the autotransporter pathway and the chaperone-usher … Visa mer
