Infection

Infection is the invasion of a host organism's bodily tissues by disease-causing organisms, their multiplication, and the reaction of host tissues to these organisms and the toxins they produce. Infections are caused by microorganisms such as viruses, prions, bacteria, and viroids, and larger organisms like macroparasites and fungi.

Famous quotes containing the word infection:

    This royal throne of kings, this sceptred isle,
    This earth of majesty, this seat of Mars,
    This other Eden, demi-paradise,
    This fortress built by nature for herself
    Against infection and the hand of war,
    This happy breed of men, this little world,
    This precious stone set in the silver sea,
    Which serves it in the office of a wall,
    Or as a moat defensive to a house
    Against the envy of less happier lands;
    This blessèd plot, this earth, this realm, this England.
    William Shakespeare (1564–1616)

    No science is immune to the infection of politics and the corruption of power.

    What, then, was war? No mere discord of flags
    But an infection of the common sky
    That sagged ominously upon the earth
