Question

Quizplus · Accepted Answer

It is possible that the original infection was caused by bacteria that were resistant to the first two antibiotics prescribed, and these bacteria continued to multiply despite treatment, leading to a recurrence of symptoms. A culture and sensitivity test could be done to determine which antibiotics are most effective against the specific bacteria causing the infection.
