MICROBIO Protozoans
Protozoans: amoeba, flagellates, cilliates, & sporozoas
| Question | Answer |
|---|---|
| amoeba; transmitted through the ingestion of cysts in feces | Entamoeba histolytica |
| free-living amoeba found in water; they can live and produce on the eye surface | Acanthamoeba spp. |
| free-living amoeba found in water; can cause brain infection (affects CNS) | Balamuthia spp. |
| transmitted through the ingestion of encysted forms of flagellates in the feces | Giardiasis |
| flagellate protozoa that infects the GI tract | Giardia lamblia |
| sexually-transmitted disease; a venereal disease (doesn't form cysts); causes urinary/genital infections | Trichomoniasis |
| flagellate protozoan found in the vagina and urethra of women, in the prostrate gland of men | Trichomonas vaginalis |
| transmitted by the tsetse fly; if caught before reaching CSF, the disease can be treated; if not, death is more probable | African Sleeping Sickness |
| a chronic disease of humans that can occur in cattle, goats, sheep, cats, and dogs | Trypanosoma gambiense |
| The ____ will vary their surface antigens, making it difficult (if not impossible) to manufacture effective vaccines. | trypanosomes |
| disease transmitted by the kissing bug; may be found in Southern states, mostly | Chagas disease |
| associated with smooth muscle, intestines, GI tract; causes heart damage | Trypanosoma cruzi |
| transmitted by the sand fly | Leishmaniasis |
| causes visceral Leishmaniasis in humans and carnivores | Leishmania donovani |
| reservoir hosts are forest rats, dogs; causes mucocutaneous Leishmaniasis in humans | Leishmania braziliensis |
| causes cutaneous Leishmaniasis in humans and dogs | Leishmania tropica |
| a serious disease in humans, albeit mild in domestic animals and monkeys | Trypanosoma rhodesiense |
| balantidiasis; transmitted through the ingestion of encysted forms in feces; pigs serve as a reservoir | Ciliate Dysentery |
| Ciliate dysentery | Balantidium coli |
| Apicomplexans | Sporozoa |
| Transmitted by the female Anopheles mosquito; the affected red blood cells may rupture at night | Malaria |
| transmitted by the female Anopheles mosquito; the sporozoans can travel to the liver, where they develop and multiply until the liver cells burst, before moving on to invade the erythrocytes | Plasmodium falciparum Plasmodium malariae |
| causes Malaria | Plasmodium vivax |
| disease that can be carried by domestic cats; can also be acquired by eating undercooked meats with cysts; is teratogenic (affects embryonic development) | Toxoplasmosis |
| sporozoa found in healthy humans lungs; a disease in those that are immunocompromised (i.e. ppl with AIDS) | Pneumocystic Pneumonia |
| sporozoa transmitted in feces of cows, rodents, dogs and cats; found in contaminated water as well; causes minor diarrhea | Cryptosporidiosis |
