Entamoeba histolytica is an invasive enteropathogenic parasite protozoa that causes amebiasis amebiasis. Amoebic dysentery is caused by protozoan parasites Entamoeba histolytica. Invasive intestinal parasite infection can cause symptoms of fulminant dysentery, such as fever, chills, bloody or mucoid diarrhea, and abdominal discomfort. Dysentery can alternate with periods of constipation or remission. https://www.ncbi.nlm.nih.gov › pmc › Article › PMC2943803

What can Enamoeba cause?

amebiasis is a disease caused by the parasite Entamoeba histolytica. It can affect anyone, although it is more common in people living in tropical areas with poor sanitation. Diagnosis can be difficult because other parasites look very similar to E. coli.

What type of parasite is Entamoeba histolytica?

Entamoeba histolytica is An anaerobic parasitic amoeba, part of the genus Enamoeba. E. histolytica primarily infects humans and other amebiasis-causing primates and is estimated to infect approximately 35-50 million people worldwide.

What class of protozoa does the E. histolytica parasite belong to?

Entamoeba histolytica is a protozoa that belongs to ancient amoeba. Archamoebae differs from other Amoebozoa species by their lack of mitochondria. Therefore, the species belonging to Archamoebae are those that perform anaerobic respiration.
