Etymology

Origin of bacteriology

First recorded in 1880–85; bacterio- + -logy

Explanation

Bacteriology is the science of certain single-celled microorganisms, both the harmful ones that cause diseases and the helpful ones in yogurt and kimchi. Bacteriology is formed by adding the suffix -ology, or "science," to bacteria, whose root means "staff," from the shape of the earliest bacteria viewed through a microscope. This branch of biology focuses on every aspect of bacteria, particularly the way medicine can be used to prevent and cure bacterial diseases.
