These agents are used for suspected bacterial infections. Ampicillin in combination with an aminoglycoside such as gentamicin is the therapy of choice. Listeria is not susceptible to cephalosporins of any generation. Therefore, cephalosporins should not be used to treat Listeria infections.
Ampicillin (Marcillin, Omnipen, Polycillin, Principen)
DOC. Interferes with synthesis of cell wall mucopeptide during active multiplication, resulting in bactericidal activity.
Sulfamethoxazole and Trimethoprim (Bactrim, Cotrim, Septra)
Second-line DOC for non-neonatal penicillin-allergic patients. Inhibits bacterial growth by inhibiting synthesis of dihydrofolic acid.
Penicillin G (Pfizerpen)
Can be used as an alternative to ampicillin. Interferes with synthesis of cell wall mucopeptide during active multiplication, resulting in bactericidal activity.
MICROBIOLOGY
Sero-types 1/2a, 1/2b, and 4b cause almost all human infections and serotype 4b is associated with outbreaks.
Infections
If started as empiric therapy and patient found to have Listeria- stop dexamethasone.
