In vitro resistance of Enterobacter cloacae isolated from fresh seafood to colistin

Abstract INTRODUCTION: Enterobacter cloacae is a clinically important bacterium from the Enterobacteriaceae family. This study evaluated resistance of E. cloacae strains from fish (n=14) and shrimp (n=9) to colistin. METHODS: Biochemical identification and antimicrobial susceptibility tests were car...

Description
Summary:Abstract INTRODUCTION: Enterobacter cloacae is a clinically important bacterium from the Enterobacteriaceae family. This study evaluated resistance of E. cloacae strains from fish (n=14) and shrimp (n=9) to colistin. METHODS: Biochemical identification and antimicrobial susceptibility tests were carried out in an automated Vitek®2 instrument. RESULTS: Colistin resistance was observed in 21.4% and 66.7% of the strains from fish and shrimp, respectively. We observed minimum inhibitory concentrations of ≥16 mg/L and ≤5 mg/L in 8 and 15 of all strains, respectively. CONCLUSIONS: Fish and shrimp can carry drug-resistant enterobacteria, which can be of clinical interest.
