Bacteriology: The science and study of bacteria and their relation to medicine and to other areas such as agriculture (e.g., farm animals) and industry. Bacteria are single-celled microorganisms which can live as independent organisms or, dependently, as parasites. Among the better known bacteria are strep, staph, and the agents of tuberculosis and leprosy.
Bacteriology is a part of microbiology which encompasses the study of bacteria, viruses, and all other sorts of microorganisms.
Bacteriophage: A virus that lives within a bacterium, replicating itself and eventually destroying the bacterial cell. Bacteriophages have been very helpful in the study of bacterial and molecular genetics. They are sometimes simply called phages.
Bacteriostatic: Capable of inhibiting the growth or reproduction of bacteria. Different from bactericidal (capable of killing bacteria outright).
