Explain why a person with overt symptoms of intestinal Entamoeba histolytica infection is unlikely to transmit infection to others.
To determine:
The reason why person with overt symptoms of intestinal Entamoeba histolytica infection is unlikely to transmit infection to others.
Introduction:
It is often seen that person with overt symptoms of Entamoeba histolytica suffer from extreme diarrhea. It is harbored by chronic carriers whose intestines favor the encystment stage of the life cycle.
Explanation of Solution
Humans are the primary carriers and the symptoms of amebiasis include dysentery. Hence, the cysts are flushed in the feces rapidly, but after recuperation, cysts are continuously shed in feces.
Hence, it may be concluded that, the constant flushing of cysts in feces the infection is unlikely to transmit to others.
