NPPA and abscess: The etiology of most liver abscesses is not clear, so these abscesses are characterized by cryptogenesis.[2] Because KP strains may colonize the human gastrointestinal tract, it is most likely that KP translocations through the gastrointestinal tract lead to the formation of liver abscesses.[3,4] In recent years, KP has become an important cause of liver abscess in Asian people.
