From the Latin “veterinarious”, which comes from “vetus”, meaning “old” or “experienced” (as in the word “veteran”). Veterinarious is associated with the Latin “veterinum“, which denotes “beast of burden”.
The term derives from the ancient Greek noun “bacterion”, diminutive of “baktron”, meaning “stick” (probably used in the expression “bakteria ravdos” meaning walking stick or shepherd’s staff).
The term “bacterium”, denoting rod-shaped microorganism, was introduced in microbiology by the German naturalist Christian Gottfried Ehrenberg in 1838 and became the basis of the French “bactérie” and the English “bacteroid”.
The word “baktron” was also the origin of the noun “bacteridion”, which was used during the Hellenistic period in Greek (323 B.C. – 31 B.C.), as diminutive of bacterion. The word “bacteridion” has been used in science as the basis of the name of a genus of sea gasteropods (snails): “Bacteridium”.
