A substance produced by or derived from a microorganism and able in dilute solution to inhibit or kill another microorganism.
Resistance to one or more antibiotics, usually due to additional genetic information.
A cylindrical or rod-shaped bacterium
A sphereical bacterium
A method for the differential staining of bacteria that involves fixing the bacterial cells to a slide and staining with crystal violet and iodine, then washing with alcohol, and conterstaining with safranin. Results in gram-positive bacteria retaining the purple dye and gram-negative organisms having it decolorized so that the red counterstain shows up.
Zone of Inhibition
Region around a chemical saturated disc, where bacteria are unable to grow due to adverse effects of the compound in the disc.
Drugs that act, are effective, or are directed against viruses.
The protein shell that encloses a viral genome. It may be rod-shaped, polyhedral, or more complex in shape.
A microscope that focuses an electron beam through a specimen, resulting in resolving power a thousand-fold greater than that of a light microscope.
A double layer of lipid surrounding the viral capsid.
Cell on or in which smaller organisms or viruses live, feed, and reproduce.
A process of disintegration or dissolution, as of cells.
A complete virus particle that consists of an RNA or DNA core with a protein coat sometimes with an external envelope and that is the exracellular infective form of a virus.
Any of a large group of submicroscopic infective agents that are regarded either as extemely simple microorganisms or as extremely complex molecules, that typically contain a protein coat surrounding an RNA or DNA core of genetic material but no cell membrane, that are capable of growth and multiplication only in living cells, and that cause various important diseases in humans, animals, or plants.
A substance (as hydrogen peroxide) that inhibits the growth or action of microorgansims especially in or on living tissue.
An infectious disease communicable by contact with one who has it, with a bodily discharge of such a patient, or with an object touched by such a patient.
Affecting or tending to affect an atypically large number of individuals within a population, community, or region at the same time.
A condition of being able to resist a particular disease especially through preventing reproduction of a pathogenic microorganism or by counteracting the effects of its products.
Capable of causing infection.
Occurring over a wide geographic area and affecting an exceptionally high proportion of the population.
Causing or capable of causing a disease.
A restraint upon the activities or travels of persons or the transport of goods that is designed to prevent the spread of disease or pests.
The promotion of hygiene and prevention of disease by maintenance of clean conditions.
Free from living organisms and especially microorgansims.
The introduction into humans or demstic animals of microorganisms that have previously been treated to make them harmless for the purpose of inducing the development of immunity.
Able to overcome bodily defense mechanisms to cause infection or disease.
