Mixed bacteremia with Vibrio metschnikovii in an 83-year-old female patient.

An 83-year-old woman suddenly fell ill and was admitted to the hospital on suspicion of a heart attack. After admission she developed high fever, chills and malaise. Vibrio metshnikovii and Staphylococcus hominis were isolated from 2 separately obtained blood cultures. One of the cultures also yielded Escherichia coli. The patient's condition improved rapidly after treatment with ampicillin intravenously. To our knowledge, this is the fourth reported case of V. metschnikovii bacteremia in humans.
