Explain the structure and life cycle of entamoeba histolytica with the help of labelled diagram
Answers
Answer:
histolytica live in the mucosal and submucosal layers of the large intestine of man. Life cycle of Entamoeba histolytica has two-stage: motile trophozoite and non-motile cyst. Trophozoites are found in intestinal lesions, extra-intestinal lesions, and diarrheal stools whereas cyst predominates in non-diarrheal stools.
Answer:
Entamoeba histolytica is an anaerobic parasitic amoebozoan, part of the genus Entamoeba. Predominantly infecting humans and other primates causing amoebiasis, E. histolytica is estimated to infect about 35-50 million people worldwide. E. histolytica infection is estimated to kill more than 55,000 people each year. Previously, it was thought that 10% of the world population was infected, but these figures predate the recognition that at least 90% of these infections were due to a second species, E. dispar.[3] Mammals such as dogs and cats can become infected transiently, but are not thought to contribute significantly to transmission.
