Abstract

Background: Klebsiella pneumoniae is an important causative agent of hospital-acquired infections, including severe pneumonia, urinary tract infection as well as septicemia and wound infections. Objective: Analyzing the antibiotic resistance of Klebsiella pneumoniae at Can Tho Central General Hospital in 2019. Materials and methods: 256 medical records at ICU and Infectious Respiratory Department with Klebsiella pneumoniae infection according to CLSI guidelines. Results: Antibiogram results show that antibiotics of Beta - lactam group had a high rate of resistance, specifically: cephalosporine family: cefazolin (83.8%), ceftriaxone (80.2%), ceftazidime (80.4%), cefepime (78.1%). Penicillin family: moderate spectrum: ampicillin (99.2%), amoxicillin/clavulanic acid (76.4%), ampicillin/sulbactam (83.8%), piperacillin (87.5%), broad spectrum: ticarcillin (100%), ticarcillin / clavulanic acid (50.0%) piperacillin/tazobactam (66.3%). Monobactam family: aztreonam (100%). Some other groups of antibiotics also had high resistance such as fluoroquinolone and nitrofurantoin group with resistance level > 70%. Among the carbapenems, imipenem had the highest rate of resistance at 54.5%. Conclusion: Antibiotic indications must be based on microbiological evidence in order to improve the effectiveness of resistance reduction.
