Root Explanation

Bacitracin is derived from 'Bacillus' (a genus of bacteria) and 'tracin' (from the Latin 'tractus', meaning to draw or pull). The name refers to the antibiotic's origin from the Bacillus subtilis bacteria, which produces the substance that draws out or inhibits bacterial growth.

Memory Tip

Think of 'Bacillus' as the source of the antibiotic, and 'tracin' as something that helps to 'draw out' harmful bacteria. This helps you remember that bacitracin is an antibiotic derived from a specific bacterium.
