SUMMARY
Antibiotic Resistance of Citrobacter Strains Isolated Between 2015 and 2017
Citrobacter is a group of bacteria that causes hospital-acquired infections mostly in newborn and immunosuppressed patients. The aim of this study to antibiotic resistance of Citrobacter strains isolated from clinical specimens between April 2015 and March 2017 as infection agents. 37 C.freundii and 35 other Citrobacter strains, totally 72 Citrobacter strains were isolated. When MIC values of isolates were taken into consideration altogether, rate of resistance were as follows : 99 % to ampicillin, 25 % to ceftazidime, 22 % to trimethoprim/sulfamethoxazole and aztreonam, 15 % to ciprofloxacin, 11 % to piperasillin/ tazobactam and gentamisin, 10 % to cefepime, % 1 to meropenem and % 0 to amikacin, amikacin and meropenem are determined
Background/aim: Enterobacter species often colonise human gastrointestinal tract, causing various opportunistic infections. Enterobacter cloacae and Enterobacter asburiae are the most frequently isolated Enterobacter species. The aim of this research was to investigate antimicrobial resistance among Enterobacter spp. strains isolated from patients in a tertiary hospital of Southeastern Turkey. There are few publications on antibiotic resistance of Enterobacter species.
Materials and methods:This retrospective study included Enterobacter spp. strains isolated from clinical specimen sent from Dicle University Hospital clinics from 2015 to 2017. The isolates to be considered as infection agents were identified by MALDI-TOF mass spectrometry. The antimicrobial susceptibility test (AST) was carried out by semiautomated microbiology system and evaluated according to EUCAST v.8.0 criteria.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
