Bacteriology (redirected from bacteriologist)

bacteriology

Study of bacteria. Modern understanding of bacterial forms dates from Ferdinand Cohn's classifications. Other researchers, such as Louis Pasteur, established the connection between bacteria and fermentation and disease. The modern methods of bacteriological technique began in the late 19th century with the use of stains and the development of methods of cultivating organisms on plates of nutrients. Important discoveries came when Pasteur succeeded in immunizing animals against two bacterial diseases, which led to the development of immunology. See also microbiology.

Bacteriology

The science and study of bacteria, and hence a specialized branch of microbiology. It deals with the nature and properties of the bacteria as living entities, their morphology and developmental history, ecology, physiology and biochemistry, genetics, and classification.

The major subjects that have consecutively occupied the forefront of bacteriological research have been the origin of bacteria, the constancy or variability of their properties, their role as causative agents of disease and of spoilage of foods, their significance in the cycle of matter, their classification, and their physiological, biochemical, and genetic features.
