Study Notes
Parasites
- Parasites that require a host to live are known as parasites.
- Phylum of kinetoplast: structure is seen in parasites under this phylum.
- Circulatory system is absent in some parasites.
Protozoa
- Intestinal amoeba:
- Entamoeba histolytica:
- Can cause extra-intestinal infection
- Can spread to liver, lungs, and brain through the bloodstream
- Causes hepatic amoebiasis, where an amoebic liver abscess is formed
- Entamoeba coli:
- Nonpathogenic commensal
- Larger than E. histolytica (20-50 um)
- Sluggish motility
- Life cycle is the same as E. histolytica but does not invade tissue
- Free-living amoeba:
- Naegleria fowleri
- Acanthamoeba spp.
- Iodamoeba butschlii
- Intestinal and atrial flagellates and ciliates:
- Giardia lamblia
- Dientamoeba fragilis
- Blastocystis hominis
- Trichomonas vaginalis
- Balantidium coli
Blood and tissue sporozoa
- Plasmodium:
- P. vivax
- P. ovale
- P. malariae
- P. knowlesi
- Leishmania spp.
- Trypanosoma spp.
- Babesiosis
- Toxoplasma gondii
- Pneumocystis carinii
