  • Amoebiasis (a parasitic disease caused by Entamoeba histolytica or Entamoeba dispar)

Metronidazole is also used to treat certain types of anaerobic bacterial infections, such as those caused by Bacteroides fragilis. This is a type of bacteria that lives in the colon and can cause inflammation or abscesses there. The drug may also be used to treat peritonitis (inflammation of the abdominal lining) caused by Clostridium difficile.
