Anchovy sauce: Anchovies are a family of small, common salt-water  fish. Here you see Anchovy sauce in a bowl in the first picture. The picture underneath shows pus aspirated from a liver abscess confirmed to be due to entamoeba histolytica. 
Worldwide, Amoebic liver abscess is more common than pyogenic liver abscess.It is common in under developed countries. The disease is caused by ENTAMOEBA HISTOLYTICA. Infarction, enzymatic hydrolysis and immunological reaction either independently or in combination results in an abscess.The color has been described as “like anchovy sauce”. Anchovy sauce like pus is not always amoebic. It is not typical of amoebic liver abscess and has been over stressed in the past. The pus is usually chocolate colored or pinkish brown.
