Carbapenem-resistant Klebsiella pneumoniae (CRKP) is a challenge in clinical anti-infection treatment. Herein, we report the case of CRKP sepsis in an extremely low-birth weight infant (ELBWI) who did not respond to meropenem and vancomycin, but was treated successfully after a 10-day antibiotic course with trimethoprim–sulfamethoxazole (TMP-SMZ). Recent research on CRKP-associated sepsis and the application of TMP-SMZ therapy in children and neonates were reviewed to offer a reference for clinical practice.Keywords: carbapenem-resistance, extremely low birth weight infant, Klebsiella pneumoniae, sepsis, trimethoprim–sulfamethoxazole
