Did You Know?

Most chemical names are made up of two or more Greek and Latin roots strung together. Thus, tetracycline, with its cycl- root from the Greek word for "circle", means "four-ringed"—that is, "consisting of four fused hydrocarbon rings". Antibiotics work against bacteria and other tiny organisms (but not viruses); tetracycline, which comes from a kind of soil bacteria, is one of the most used of the antibiotics. "Broad-spectrum" antibiotics work well on numerous organisms; thus, tetracycline has proved effective against acne, chlamydia, cholera, rickets, and various lung and eye infections, among many other conditions.
