Which of the following terms describes when antibiotics are not effective against some bacteria?
a. dependence
b. anaphylaxis
c. resistance
d. tolerance
c. Antibiotic use promotes development of antibiotic-resistant bacteria. Bacterial resistance to the antibiotic renders the antibiotic ineffective, thereby allowing the progression of the infection. The bacteria continue to multiply, grow, and survive in the presence of concentrations of an antibiotic that are usually lethal to organisms. Antimicrobial resistance is an increasing problem worldwide. The danger is that when antibiotics are used unnecessarily, they will not be effective if administered later for a serious bacterial infection.
