Acute Cholangitis With Non-O1 and Non-O139 Vibrio cholerae Bacteremia: A Case Report
Abstract
We describe a case of acute cholangitis with bacteremia caused by non-O1 and non-O139 Vibrio cholerae (NOVC) in a 76-year-old man following acute gastroenteritis. The strain, isolated from blood cultures, was identified as serogroup O120. It lacked the cholera toxin gene, but it harbored multiple virulence genes, including hlyA, rtxA, vscV2, and vspD. Risk factors included total gastrectomy, diabetes, and prior biliary interventions. Although the patient's diarrhea had resolved by the time of admission, dietary history and timely blood cultures enabled an accurate diagnosis. This case highlights the invasive potential of NOVC strains harboring alternative virulence determinants in immunocompromised hosts.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
