Intestinal Protozoa and Flagellates
According to Foo et al, (13) Entamoeba histolytica is an anaerobe parasitic amoebozoa part of the genius Entamoeba.it predominantly infects other primates as well as humans causing amoebic dysentery.
Entamoeba hartmanni is an amoeba that depends on humans through symbiosis. There are two types of cysts present in recently formed stool and trophozoites found in diarrhea stool.
Entamoeba coli is a non- pathogenic entity of Entamoeba doesn’t move much, therefore, keeping its round shape and is only visible in fresh and unfixed stool specimen (Cindy, 1).
Cindy (1) argues that Endolimax nana is a non-pathogen and is acquired through fecal-oral transmission in cyst form contained in contaminated food or water.
Iodamoeba butschlii is a non-pathogenic parasite found in the large intestines of humans, pigs among other mammals.
Low levels of this parasites in diarrhea in humans (Foo et al, 13).
Acanthamoeba is an independent living ameba that causes eye infections, skin and nervous system complications (Foo et al, 13).
It is spread through broken skin, eye lenses or through inhalation.
Naegleria fowleri is an independent bacteria-eating protozoan that is pathogenic and causes fulminant.
Giardia lamblia is an organism with flagella a parasite that colonizes and reproduce in the ileum and cause giardiasis. (Cindy, 1)
Diebtamoeba fragilis is a single-celled species found in human, pigs and gorillas’ gastrointestinal tract.it causes failure of thriving in children (Foo et al, 13).
Trichomonas vaginalis is a protozoa parasite that causes a sexually transmitted disease called trichomoniasis and is transmitted through sex residing in the lower section of the genital tract in females (Cindy, 1)
According to Cindy,(1) Chilomastix mesnili depends on symbiosis for survival as it is not parasitic.it is mainly found in monkeys, pigs and lives at the beginning of the large intestines and large bowel.
Balantidium coli is a parasite that causes balantidiasis and is pathogenic to human beings. Just as Entamoeba hartmanni it has two development stages (Foo et al, 13).
