Scanning electron micrograph (SEM) revealed some of the ultrastructural morphology displayed on both the dorsal surface (LT), and ventral surface (RT) of two bedbugs, Cimex lectularius. Although bedbugs have been found naturally-infected with blood-borne pathogens, they are not effective vectors of disease. The primary medical importance is inflammation associated with their bites (due to allergic reactions to components in their saliva).
