Related to the study of bacteria and their effects on living organisms.
The bacteriologic analysis revealed the presence of harmful bacteria in the water.
Bacteriologic → It is formed from "bacterium" (from Greek "bakterion", meaning small staff or rod) and "-logic" (from Greek "logia", meaning study or science). The word refers to the scientific study of bacteria.
Think of 'bacterium' as the small rod-shaped organisms being studied in 'logic' or science — that's why bacteriologic means the study of bacteria.
