How is bacterial liver abscess caused

Bacterial liver abscess may be caused by bacterial infection, poor bile drainage, inflammation and other reasons.

1. Bacterial infection

Escherichia coli, Proteus, anaerobic streptococci, Staphylococcus aureus and other bacteria infected liver, may cause bacterial liver abscess.

2. Bile drainage poor

biliary stones, biliary ascaris, biliary tumors and other diseases may lead to biliary obstruction, making bile drainage poor, biliary pressure increased, easy to breed a large number of bacteria and cause bacterial liver abscess.
