microorganism

(mī´krō ōr´gənizəm),
n a microscopic living organism, such as a bacterium, virus, rickettsia, yeast, or fungus. These may exist as part of the normal flora of the oral cavity without producing disease. With disturbance of the more or less balanced interrelationship among the organisms or between the organisms and host resistance, individual forms may overgrow and induce disease in the host's tissues. Those foreign to the individual may invade and produce pathologic processes.
