Abstract
Vibrio anguillarum is a cause of vibriosis in marine fisheries worldwide, but only one previous study reported human pathogenicity of this species. Here, we report a 70-year-old man from Dalian, a coastal city in northeast China, who experienced a severe infection with V. anguillarum due to a bite on his left hand when handling hairtail, a marine fish. This patient had low immunity because of the long-term use of glucocorticoids due to nephrotic syndrome. Despite treatments consisting of a strong antibiotic, continuous veno-venous hemofiltration, debridement, and fasciotomy, his condition deteriorated and he died of septic shock and multiple organ dysfunction syndrome. His death might be partly due to the delayed amputation of the left forearm, because he seemed to get better for the first several days. This case report emphasizes the possibility of human infection by V. anguillarum, which is likely to be more lethal in immunocompromised individuals.
