Bacterial Adhesion to Host Tissues: Mechanisms and by Michael Wilson

By Michael Wilson

Adhesion is the an important first level in any infectious ailment. it's hence very important to completely comprehend the mechanisms underlying bacterial adhesion in order that we are able to increase tools of retaining our general (protective) microflora, and of forestalling pathogenic micro organism from beginning an infectious method. This booklet describes the bacterial constructions accountable for adhesion and the molecular mechanisms underlying the adhesion procedure. a different characteristic is that it additionally offers with the implications of adhesion for either the adherent bacterium and the host cell/tissue to which it has adhered.

One consequence of pilus-mediated adhesion to endothelial cells is increased cellular damage, which is mediated primarily by LPS (Fig. , 1995; Dunn and Virji; 1996). Thus multiple ligation of receptors via LPS and pili augment cellular signalling events that result in cell death.
