Which antibiotic provides coverage for Bacteroides fragilis?

Ciprofloxacin
Metronidazole
Cefepime
Quinolones

The correct answer is: Metronidazole

Ciprofloxacin, Cefepime, and Quinolones are all antibiotics that do not provide coverage for Bacteroides fragilis. Ciprofloxacin and Quinolones are both broad spectrum antibiotics that work best against gram-negative bacteria and may even lead to antibiotic resistance. Cefepime is primarily active against gram-negative bacteria, but does not provide coverage specifically for Bacteroides fragilis. Metronidazole is the only antibiotic listed that specifically targets anaerobic bacteria, such as Bacteroides fragilis. This drug works by disrupting the DNA of the bacteria, making it an effective treatment option for infections caused by Bacteroides fragilis. As always, it is important to consult with a healthcare professional before starting any antibiotic treatment.
