¹This patient is case one, and she had received the endoscopic papillotomy one day before the episode of Acinetobacter baumannii (A. baumannii) bacteremia;

²This patient had suspected hepatocellular carcinoma;

³This patient had received the percutaneous transhepatic cholangeal drainage three days before the episode of A. baumannii bacteremia, and the route of entry of A. baumannii could result from biliary tract. He was categorized to primary bacteremia due to lack of typical clinical symptoms and signs of biliary sepsis;

⁴This patient is case two, and she had received the endoscopic retrograde biliary drainage one day before the episode of A. baumannii bacteremia.
