FOR KIDS: Sponges' secret weapon

An aquatic animal provides a possible new kind of disease resistance

Bacteria are tiny, single-celled organisms that can cause disease in humans through infection. Bacteria can live almost anywhere: in soil, water, food or your body. We can cure many types of bacterial infections with the use of medicine called antibiotics, which kill the germy organisms.

Unfortunately, some types of bacteria do not respond to antibiotics. This resistance can be a big problem for humans — if our antibiotics don’t kill the bacteria, then a bacterial infection can be deadly. Some bacteria that cause ear infections, food poisoning and whooping cough, for example, can resist antibiotics.
