The plant pathogen Xylella fastidiosa is a gram negative that attaches to surfaces and forms a biofilm in host plants. Which of the following typically triggers an immune response?

a)
Pili
b)
Teichoic
acid
c)
LPS
d)
EPS

Solution

Ans--(C) : LPS

Lipopolysaccharide (LPS) is the predominant macromolecule displayed on the cell surface of Gram-negative bacteria and thus mediates bacterial interactions with the environment and potential hosts Utilizing a mutant that produces truncated O antigen we present results that link this LPS structural alteration to a significant decrease in the attachment of X,Xylella fastidiosa is a plant pathogenic bacterium that lives inside the host xylem vessels where it forms biofilm believed to be responsible for disrupting the passage of water and nutrients.
