Solution:
Amoebic dysentery is the infection of the large intestine caused by Entamoeba histolytica, a monogenetic parasite. The tetranucleate cyst is the infective stage of Entamoeba histolytica. The incubation period of the cyst of Entamoeba histolytica may vary from five days to several months. Abdominal pain, constipation, and blood in the faeces are the main symptoms of this disease.
Magna is the most active, motile, and feeding form which is pathogenic to man.
Minuta is a stage where Entamoeba histolytica is smaller, spherical, and non- pathogenic. It lives in the lumen of the intestine and rarely found in tissues.
Binucleate cyst stage is before tetranucleate stage wherein the nucleus of the cysts divides once so that each cyst now becomes binucleate.
