ICD-10 Specific code A01.4: Paratyphoid fever, unspecified

Amoxicillin is a semisynthetic penicillin (beta-lactam antibiotic) that inhibits one or more enzymes (often referred to as penicillin-binding proteins, PBPs) in the biosynthetic pathway of bactericidal peptidoglycan, which is an integral structural component of the bacterial cell wall. Inhibition of peptidoglycan synthesis leads to weakening of the cell wall, which is usually followed by cell lysis and death.

Ceftolozane belongs to the cephalosporin class of antimicrobials. Ceftolozane exerts bactericidal activity through binding to important penicillin-binding proteins (PBPs), resulting in inhibition of bacterial cell-wall synthesis and subsequent cell death.

Tetracyclines have a broad spectrum of anti-microbial activity and act by interfering with bacterial protein synthesis. They are active against a large number of gram positive and gram negative pathogenic bacteria, including some which are resistant to penicillin.

Minocycline is a semi-synthetic derivative of tetracycline. Minocycline inhibits protein synthesis in susceptible bacteria. In common with other tetracyclines it is primarily bacteriostatic and has a similar spectrum of activity to other tetracyclines.

Piperacillin is a broad-spectrum, semisynthetic penicillin. Piperacillin exerts bactericidal activity by inhibition of both septum and cell-wall synthesis.

Ticarcillin disrupts bacterial cell wall development by inhibiting peptidoglycan synthesis and/or by interacting with penicillin-binding proteins.
