Answer: All of the above
A. Multiply in the endothelial cell of small blood
vessels and produce vasculitis
B. Has protein adhesion that seres as attachment to Source: Rickettsiae contain lipopolysaccharide, and
host cell
the cell wall proteins include the surface proteins

E. All of the above
basis for serotyping. Rickettsiae multiply in
endothelial cells of small blood vessels and produce
vasculitis characterized by lymphocytes that
surround the blood vessels. Vascular lesions are
prominent in the skin, but vasculitis occurs in many
organs and appears to be the basis of hemostatic
disturbances. Disseminated intravascular coagulation
and vascular occlusion may develop. In the brain,
aggregations of lymphocytes, polymorphonuclear
leukocytes, and macrophages are associated with
the blood vessels of the gray matter; these are called
“typhus nodules.”
