A scientist wanted to formulate a pill to attack a specific type of bacteria that infects the throat. Which biological component would be best to use as a model for the pill’s function?

Antibodies recognize and bind to specific antigens on particular bacteria, so they provide a model for a pill designed to target one type of throat-infecting bacteria. The complement system and phagocytes help defend against pathogens more generally, while bacteriocytes are cells that house symbiotic bacteria.
