Laribacter hongkongensis is an emerging pathogen in patients with community-acquired gastroenteritis and traveler's diarrhea. We herein report a case of L. hongkongensis infection in a 24-yr-old male with liver cirrhosis complicated by Wilson's disease. He was admitted to a hospital with only abdominal distension. On day 6 following admission, he complained of abdominal pain and his body temperature reached 38.6℃. The results of peritoneal fluid evaluation revealed a leukocyte count of 1,180/µL (polymorphonuclear leukocyte 74%). Growth on blood culture was identified as a gram-negative bacillus. The isolate was initially identified as Acinetobacter lwoffii by conventional identification methods in the clinical microbiology laboratory, but was later identified as L. hongkongensis on the basis of molecular identification. The patient was successfully treated with cefotaxime. To the best of our knowledge, this case is the first report of hospital-acquired L. hongkongensis bacteremia with neutrophilic ascites.
香港阿克曼菌是一种引起社区获得性胃肠炎和旅行者腹泻的新兴病原体。本研究报告了 1 例 24 岁合并肝硬变、Wilson 病的男性患者感染香港阿克曼菌。患者因腹胀入住医院，入院第 6 天出现腹痛，体温达 38.6℃。腹腔液检查结果显示白细胞计数为 1180/µL（中性粒细胞 74%）。血培养生长出革兰阴性杆菌。临床微生物实验室的常规鉴定方法最初将分离株鉴定为鲁氏不动杆菌，但后来基于分子鉴定将其鉴定为香港阿克曼菌。该患者经头孢噻肟治疗后痊愈。据我们所知，这是首例中性粒细胞性腹水的医院获得性香港阿克曼菌菌血症的报告。
