Viral Structure and Function
Coxsackie B viruses are single-strand positive-sense RNA viruses that are resistant to a wide variety of chemical treatments. The viral particles themselves are roughly 30 nm icosahedrons. The virus is most frequently distributed via the fecal-oral route, and infection commonly occurs after eating contaminated food. Coxsackie B viruses are cytolytic, and Coxsackie B2 and B5 viruses have been implicated in hand, foot and mouth disease as well as respiratory infection. Infection in infants is mostly asymptomatic, but sometimes results in the death of the infant, often due to myocarditis. Birth defects may also be present in a Coxsackie B infected infant.

Famous quotes containing the words structure and/or function:
“Who says that fictions only and false hair
Become a verse? Is there in truth no beauty?
Is all good structure in a winding stair?
May no lines pass, except they do their duty
Not to a true, but painted chair?”
—George Herbert (1593–1633)
“As a medium of exchange,... worrying regulates intimacy, and it is often an appropriate response to ordinary demands that begin to feel excessive. But from a modernized Freudian view, worrying—as a reflex response to demand—never puts the self or the objects of its interest into question, and that is precisely its function in psychic life. It domesticates self-doubt.”
—Adam Phillips, British child psychoanalyst. “Worrying and Its Discontents,” in On Kissing, Tickling, and Being Bored, p. 58, Harvard University Press (1993)
