Question

1: Ampicillin 2: Erythromycin 3: Tetracycline 4: Chloramphenicol

1: If you had a patient with a urinary tract infection caused by the strain of E. coli you tested in this exercise, which (if any) of the antibiotics tested would you use to treat the infection? Briefly explain your choice.

2: If you had a patient with a urinary tract infection caused by the strain of S. saprophyticus you tested in this exercise, which (if any) of the antibiotics tested would you use to treat the infection? Briefly explain your choice.

Answer 1

1. Based on the results of the exercise, ampicillin would not be effective in treating a urinary tract infection caused by the strain of E. coli tested. Erythromycin, tetracycline, and chloramphenicol all showed some level of effectiveness against the strain of E. coli tested. However, tetracycline had the highest level of effectiveness, so it would be the best choice for treating the infection.

2. Based on the results of the exercise, erythromycin would be the best choice for treating a urinary tract infection caused by the strain of S. saprophyticus tested. Erythromycin was the only antibiotic tested that showed any level of effectiveness against the strain of S. saprophyticus tested. While the level of effectiveness was not very high, it was the only option available, so erythromycin would be the best choice.
