D
Feedback:
The goal of anti-infectives is to interfere with the normal function of the invading organism to prevent it from reproducing and to cause cell death without affecting host cells. Each class of anti-infectives works in a different way, but all have the same goal. Because bacteria cells have a slightly different composition than human cells, the bacteria are destroyed without interfering with the host. The first drugs used to treat systemic infections were developed in the early 20th century. The term selective toxicity refers to the ability to affect certain proteins or enzyme systems that are used by infecting organisms, but not by human cells.
