We describe a case of acute cholangitis with bacteremia caused by non-O1 and non-O139 (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 , , , and . 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.
我们描述了一例76岁男性在急性肠胃炎后发生的由非O1和非O139(NOVC)引起的伴有菌血症的急性胆管炎病例。从血培养中分离出的菌株被鉴定为O120血清群。它缺乏霍乱毒素基因,但含有多个毒力基因,包括、、和。危险因素包括全胃切除术、糖尿病和既往胆道干预。尽管患者入院时腹泻已缓解,但饮食史和及时的血培养使得能够做出准确诊断。该病例突出了在免疫功能低下宿主中携带替代毒力决定因素的NOVC菌株的侵袭潜力。
