A gold coin that was the basic monetary unit of ancient Rome, or in modern usage, a species of pathogenic bacteria (Staphylococcus aureus). The Roman coin was valued for its high gold content and widespread acceptance.
From Latin 'aureus' meaning 'golden', derived from 'aurum' (gold). The Roman coin was named for its gold composition and golden appearance. The bacterial name Staphylococcus aureus was chosen because the bacteria forms golden-yellow colonies when cultured, connecting ancient monetary terminology to modern microbiology.
