Evaluation of synergistic effect of tazobactam with meropenem and ciprofloxacin against multi-drug resistant Acinetobacter baumannii isolated from burn patients in Tehran
Background: is an increasingly important cause of nosocomial infections worldwide. In addition to the intrinsic resistance of to many antibiotics, available treatment approaches with older antibiotics are significantly associated with an increase in multiresistant strains.

description | Background: is an increasingly important cause of nosocomial infections worldwide. In addition to the intrinsic resistance of to many antibiotics, available treatment approaches with older antibiotics are significantly associated with an increase in multiresistant strains. The aim of this study was to evaluate the synergistic effect of tazobactam with meropenem and ciprofloxacin against carbapenems and drug resistant isolated from burn patients in a tertiary burn center in Tehran.Materials and methods: In this study, a total of 47 clinical isolates of were included from burn patients admitted to the Shahid Motahari Burns Hospital, Tehran, from June 2018 to August 2018. The disk diffusion method was used to determine resistance patterns. The synergistic effect of tazobactam with meropenem and ciprofloxacin was evaluated by determining the MIC. A PCR assay was performed to determine , and .Results: Antibiotic susceptibility testing revealed that all of the isolates were resistant to meropenem and ciprofloxacin. The MIC values decreased in the cases of combined use of ciprofloxacin and meropenem with tazobactam. The bla gene was the predominant carbapenemase gene (93.6%), followed by , which was detected in 48.9% of isolates. None of the isolates harbored the gene. Conclusions: Based on in-vitro antimicrobial susceptibility in the current study, the MIC of tazobactam combined with meropenem or ciprofloxacin have been shown to be variable. Furthermore, the data acquired from such conditions should be confirmed by reliable results from sufficiently controlled clinical trials. |
