Antibiotics are not indicated for which of the following conditions?

Antibiotics are not indicated for which of the following conditions?

• A. Chlamydia
• B. E. coli infection
• C. Gonorrhea
• D. Influenza A and B

Answer: (D)

Antibiotics work by killing or inhibiting bacteria, not viruses. Influenza A and B are caused by viruses, so antibiotics do not treat them and aren’t indicated unless a secondary bacterial infection develops. In contrast, chlamydia and gonorrhea are bacterial infections, so antibiotics are essential treatments. E. coli infections are also caused by bacteria, and antibiotics are indicated when the infection is bacterial and the organism is susceptible, with choice guided by the infection site and severity. This distinction highlights why antibiotics are not used for viral illnesses like influenza but are used for bacterial infections such as chlamydia, gonorrhea, and many E. coli–related infections.
