[Shewanella algae sepsis after bathing in the Baltic Sea].

Shewanella algae is a typical marine bacterium. It is a rare cause of disease in humans, especially in colder sea environments. In this case report, an otherwise healthy elderly male presents with sepsis caused by S. algae a few days after bathing in the Baltic Sea with open wounds from gardening. He was successfully treated with antibiotics and standard sepsis treatment. Since global temperatures are rising, infections with S. algae might become more common in Scandinavia, and clinicians in these areas should be aware of the risk of infection.
