Typhoid fever is characterized by a high fever, abdominal pain, and systemic infection, and effective antibiotic therapy is essential to prevent complications.

Ciprofloxacin, a fluoroquinolone antibiotic, works by inhibiting bacterial DNA gyrase, disrupting DNA replication and ultimately leading to bacterial cell death. It is particularly useful in areas where there is antibiotic resistance to other agents. Conversely, ceftriaxone is a cephalosporin antibiotic that affects bacterial cell wall synthesis and is used for more severe cases or when the patient is hospitalized.

In contrast, antibiotics such as amoxicillin, doxycycline, or rifampin are not typically first-line treatments for typhoid fever. Amoxicillin is less effective due to the increasing resistance of Salmonella Typhi, while doxycycline is not commonly used against this pathogen in recent treatment guidelines, and rifampin primarily targets Mycobacterium species and is not appropriate for typhoid fever management.
