Low virulent Citrobacter koseri can cause life threatening infections. Neonates and other immunocompromised patients are particularly susceptible to infection from C. koseri. Any infection due to C. koseri mandates antimicrobial therapy based on the sensitivity of the pathogen microorganism. Various types of antibiotics, including aminoglycosides carbapenems, cephalosporins, chloramphenicol and quinolones, are used for the treatment of C. koseri infections. The rational choice of antimicrobial therapy for Citrobacter infections is a challenge for clinicians because there is a sustained increase in antibacterial resistance. We reviewed antimicrobial agents used for C. koseri infections in this review.
