Protzoa
Protozoa is motile
unicellular and eukaryote.
| feature | intestine (cyst or oocyst) |
blood, RBC | tissue | |
|---|---|---|---|---|
| Amoeba アメーバ |
amoeboid motility asexual reproduction (binary fission) |
Entamoeba histolytica | free living amoeba
| |
| Flagellata 鞭毛虫 |
flagellar motility asexual reproduction (binary fission) |
Giardia intestinalis | Trypanosoma brucei gambiense/rhodesiense | Trypanosoma cruzi Leishmania spp. Trichomonas vaginalis |
| Apicomplexa アピコンプレクサ門 |
gliding motility asexual and sexual reproduction |
Cryptosporidium spp. Isospora belli Cyclospora cayetanensis |
Plasmodium spp. | Toxoplasma gondii |
- Plasmodium spp. とCryptosporidium spp.の生活環は似ている
- oocystの中にsporozoiteが含まれている
- ただしCはoocystで伝播するがPはoocystによる伝播ではない
- Transmission form
- cyst: Entamoeba hystolytica
- oocyst: Cryptosporidium spp.
- Transmission route
- fecal-oral: Giarida intestinalis
- vector-borne: Trypanosoma spp., Plasmodium spp., Leishmania spp.
- air-borne: nothing
- vertical: Toxoplasma gondii
- Reproduction
- binary fission: Giardia intestinalis
- asexual reproduction by schizogony and sexual reproduction: Plasmodium spp.
