Vibrio cholerae serogroups O1 or O139 are the aetiological agents of cholera. The pathogenicity of non-O1, non-O139 V. cholerae is less well known. These worldwide bacteria are responsible for gastrointestinal infections or, more rarely, bacteraemia in patients with an underlying disease, leading to life-threatening complications. We report a case of non-O1, non-O139 V. cholerae bacteraemia due to a haemolytic strain in a cirrhotic patient. Early antibiotherapy allowed a good outcome. The aim of this case report is to underline the virulence of non-choleragenic Vibrio strains, possibly linked to haemolysin production, and the potential danger of consuming undercooked seafood or exposing wounds to sea water in cirrhotic patients.

Non-O1/non-O139 (NOVC) strains inhabit aquatic environments and sporadically induce human illnesses. This study involved the virulence and antimicrobial genetic characterization of 176 NOVC strains, comprising 25 from clinical samples and 151 from environmental sources, collected between 2021 and 2023. The antimicrobial susceptibility of the examined NOVC population was predominantly high, exhibiting only poor susceptibility to colistin, with 89.

Infections by non-O1/non-O139 serogroups of Vibrio cholerae (NOVC) are increasing worldwide. Infected patients usually display self-limiting diarrhoea or external ear and wound infections. We present a rare case of bacteraemia secondary to NOVC infection.

Physicians should consider non-O1, non-O139 (NOVC) in the differential diagnosis of cellulitis complicated by sepsis, especially in immunocompromised patients when potential exposure exists. Due to the pathogen's potential for severe infections and rising incidence from environmental changes, we emphasize the need for increased awareness and appropriate treatment guidelines.

Article Synopsis
- Diarrhea caused by NOVC (non-O1/O139-group e) is typically mild, but a strain (XXM) was isolated from a 68-year-old surgical patient in October 2023.
- Identification of XXM involved advanced techniques like MALDI-TOF MS and whole genome sequencing, showing it was sensitive to all tested antibiotics and lacked the virulence gene.
- The genomic analysis revealed multiple virulence genes and a genetic similarity to another NOVC strain, contributing to a better understanding of NOVC pathogenicity in clinical contexts.
