Shigellosis is treated with which antibiotic?

• A. Ciprofloxacin
• B. Trimethoprim-sulfamethoxazole
• C. Azithromycin
• D. Doxycycline

Answer: (A)

Shigellosis is treated with antibiotics to shorten illness and reduce contagiousness. A fluoroquinolone like ciprofloxacin is highly effective against Shigella, has excellent oral bioavailability, and typically produces rapid symptom relief and a quicker drop in fecal shedding. This makes it a reliable first-line option in adults and many settings. Other antibiotics such as trimethoprim-sulfamethoxazole and doxycycline show increasing resistance in Shigella, and azithromycin is often reserved for children or when fluoroquinolones aren’t suitable or in regions with known resistance. For these reasons, ciprofloxacin is commonly chosen as the best option.
