Whale strandings remain poorly understood, although bacterial infections have been suggested to contribute. We isolated Edwardsiella tarda from the blood of a stranded sperm whale. The pathogen was identified with MALDI-TOF MS, confirmed by 16S rRNA gene sequencing and quantified in blood by qPCR. We report the first case of sepsis in a sperm whale. The zoonotic potential of E. tarda and the possible role of bacterial infections in the enigmatic strandings of cetaceans are discussed.
