General MicrobiologyAmoebic dysentery, caused by the protozoan parasite Entamoeba histolytica, is characterized by the presence of ghost cells in the stool. Ghost cells are the remnants of red blood cells that have been phagocytosed by the amoeba. These cells are ingested and their cytoplasm is removed, leaving only the cell membrane, which gives them a "ghost-like" appearance under the microscope. This feature helps distinguish amoebic dysentery from bacillary dysentery, which is caused by bacteria such as Shigella species. Bacillary dysentery typically shows the presence of white blood cells (pus cells) and red blood cells in the stool, but not ghost cells.

Primary prevention aims to stop disease before it starts. Pit and fissure sealants protect tooth surfaces and prevent caries formation.
Serial extraction and scaling and root planning are examples of secondary or tertiary prevention, as they involve treatment after a condition (malocclusion or periodontal disease) has already started.
Fluoride use on incipient caries is also secondary prevention as it aims to halt the progression of an already existing early lesion.
