Difference Between Amoebic Dysentery and Bacillary Dysentery

Difference between Amoebic and Bacillary Dysentery
Amoebic Dysentery	Bacillary Dysentery
Causative Agents of Amoebic and Bacillary Dysentery
Amoebic Dysentery is caused by Entamoeba histolytica	Bacillary Dysentery is caused by Shigella species and Enterohemorrhagic E. coli
Naked eye or Macroscopic Examination of Stool
Frequency of stools in bacillary and amoebic dysentery
In Amoebic dysentery patient usually, have 6-8 episodes of loose motions per day	In bacillary dysentery patient usually complains of more than 10 episodes of bloody diarrhoea
Amount of stools in amoebic and bacillary dysentery
The amount of stool is copious in case of amoebic dysentery	Patient complains of relatively small more frequent episodes of bloody diarrhoea in bacillary dysentery
Colour of stools in bacillary and amoebic dysentery
In Amoebic dysentery the colour of stool is dark red, that’s why we ask for the colour of stool while taking a history from a patient as it helps in diagnosis.	In bacillary dysentery, the colour of the stool is bright red.
Odour of stools in amoebic and bacillary dysentery
In amoebic dysentery, the stool has an offensive odour	In bacillary dysentery, the stool is usually odourless.
Consistency of stools in amoebic and bacillary dysentery
When the stool is taken in a container, in case of amoebic dysentery stool doesn’t adhere to the bottom of the container.	Stool adheres to the bottom of the container in case of bacillary dysentery
Nature of stools in amoebic and bacillary dysentery
In the case of amoebic dysentery patient’s tool consist of mucus, blood and faeces.	In case of bacillary dysentery patient’s stool consist of mucus and blood only, faeces may not present in every episode of stool, In most of the episodes patient complains of passing blood and mucus but no faeces.
The reaction of stool in bacillary and amoebic dysentery
In amoebic dysentery, stools show an acidic reaction	In bacillary dysentery, stool shows an alkaline reaction
Microscopic examination of stool of bacillary and amoebic dysentery
Number and colour of RBCs
In amoebic stool, RBCs are found clumped together and are reddish-yellow in colour.	In bacillary stools, RBCs are present discretely or form rouleaux. The RBCs are bright red in colour in case of bacillary dysentery.
Pus cells
In amoebic dysentery, only few pus cells are present	In bacillary dysentery, numerous pus cells are found during microscopic examination.
Macrophages
In amoebic dysentery only few macrophages are present in the stool.	In bacillary dysentery large and numerous macrophages are present and many macrophages contain red blood cells (RBCs)
Eosinophils
Numerous eosinophils are found in amoebic stools	Only a few eosinophils are present in bacillary stools.
Charcot-Layden crystals
In amoebic dysentery, these crystals can be seen during microscopic examination of stool	In bacillary dysentery, these crystal are absent.
Pyknotic bodies
These are commonly found in the stool of a patient of amoebic dysentery.	There are absent in the stool of a patient of bacillary dysentery.
Parasites.
Cysts or trophozoites are found	These are not seen in case of bacillary dysentery
