Recall that an adhesin is a protein or glycoprotein found on the surface of a pathogen that attaches to receptors on the host cell. Adhesins are found on bacterial, viral, fungal, and protozoan pathogens.
WebThe virulence factors include agents such as the hydrolytic enzymes, toxins, polysaccharides, and plant growth regulators secreted by the pathogen that damage or alter plant cells and provide optimal environment for the growth of the pathogen. WebAbstract. Clinical presentations of melioidosis, caused by Burkholderia pseudomallei are protean, but the mechanisms underlying development of the different forms of disease remain poorly understood. In murine melioidosis, the level of virulence of B. pseudomallei is important in disease pathogenesis and progression.
