The hypervirulent K1 serotype Klebsiella pneumoniae is responsible for a new invasive syndrome, typically associated to hepatic abscesses with extra-hepatic complications. Initially described in Taiwan, it has significantly spread to several Asian countries and more recently to Europe and North America, thus constituting an emerging and global problem. The authors describe a case report of a 64-years-old portuguese caucasian woman without any previous diseases or epidemiological risk factors such as trips or contact with Asian products or population, diagnosed with a pyogenic liver abscess with pleural effusion caused by this hyper-virulent strain. A successful clinical cure was achieved after the etiological identification and treatment with antimicrobial therapy combined with catheter drainage. This is the first identification of hypervirulent Klebsiella pneumonia ST 23 clone in Portugal in the context of an invasive syndrome.

This is the first case report from Scandinavia of a pyogenic liver abscess caused by a Klebsiella pneumoniae isolate belonging to the international hyper virulent clone ST23. The patient, an 85-year old Caucasian, had no history of foreign travel or any classical predisposing factors for infection. The isolate was hypermucoviscous of capsular serotype K1 and carried the virulence factors aerobactin, allS, kfu and rmpA. Read More

Introduction: liver abscess syndrome (KLAS) is characterized by bacteraemia, liver abscesses and metastatic infection caused by a hypervirulent strain of , usually belonging to the capsular serotype K1 or K2. Initially, KLAS was described in Eastern Asia; recently isolated cases have been reported from different parts of the world.

Case Presentation: We describe the case of a woman with KLAS including meningeal, ocular and cutaneous metastatic infection and organ dysfunctions (coagulation abnormalities, thrombocytopenia and increased creatinine level). Read More
