Question

1. what class of antibiotics would you prescribe for sue? explain your answer.
2. why are antibiotics not effective against viruses? (think back to what you learned about viruses in pbs.)

Explanation:

1. Without information about Sue's infection (such as the causative - organism), it's impossible to determine an antibiotic class. Different bacteria are susceptible to different classes like penicillins (inhibit cell - wall synthesis), cephalosporins (similar to penicillins), macrolides (inhibit protein synthesis), etc.
2. Antibiotics target specific structures or processes in bacteria. Viruses lack the cellular structures (like cell walls, ribosomes in the bacterial sense) that antibiotics act upon. Viruses are non - cellular and replicate using the host cell's machinery, so antibiotics are ineffective.

Answer:

1. Cannot be determined without more information about Sue's condition.
2. Viruses lack the cellular structures that antibiotics target and use host cell machinery to replicate.
