Abstract
Edwardsiella tarda is typically isolated from aquatic environments. It rarely causes infections in humans. Edwardsiella tarda infections in humans result from the consumption of infected or contaminated food. Here, we present a case of recurrent cholangitis and bacteraemia associated with E. tarda. An 82-year-old man with no history of seafood inoculation was admitted to our hospital because of difficulty in moving his body. The patient was diagnosed with cholangitis, and the blood culture revealed the presence of E. tarda. The patient underwent bile duct stenting and received antibiotic therapy for 14 days. Forty-four days after discharge, cholangitis recurred, and blood culture again showed the presence of E. tarda. The patient underwent bile duct stenting and antibiotic therapy for 11 days. No cholangitis or bacteraemia associated with E. tarda was observed in the following 3 years. Our case strongly suggests that colonization with E. tarda results in recurrent cholangitis and bacteraemia.
