__ these are not worms, but are instead free-living organisms (mostly one cell), a few of which may live in the bodies of mammals causing disease.
What are some diseases associated with protozoans?
__ live in the blood, lymph and tissue spaces and are transmitted indirectly by blood sucking flies
__ live in the intestinal tract and genital tract and are spread directly through the feces or genital discharges
__ the disease regardless of species is referred to as African Sleeping Sickness
Trypanosoma is the disease regardless of species is referred to as __
African Sleeping Sickness
__ effects ruminants in south africa causing Nagana using the Tsetse fly as the intermediate host between wild and domestic cattle
_ no intermediate host (unique), uses direct sexual contact in horses causing Dourine.
Trypanosoma brucci effects ruminants in south africa causing:
This hemoflagellate uses the Tsetse fly as the intermediate host between wild and domestic cattle...
Trypanosoma equiperdum has no intermediate hose(unique), uses direct sexual contact in horses causing__
Dourine "Silver Dollar"
__ this parasite lives in the cecum and colon multiplying in fluid feces and often are blamed for the diarrhea
__ is common in women but is not considered a pathogen
Trichomonas is also seen with bacteria in __ producing pyorrhea and gingival problems
Sporozoa has two classes of blood causing hemolytic anemia:
__ is a mucoflagellate of interest and are very host specific often resulting in superparasitism.
What are the three Oocyst:
- Eimeria- farm animals
- Isospora- dogs, cats, swine and small companion pets
- Toxoplasma- all domestic animals
Coccidian Life Cycle
- Sporozite are swallowed and invade cells of mucosa and divide to form Merozoites
- Merozoites leave the cells and enter new cells and develop into Male/Female Gamonts
- Gamonts mature to Macrogametes
- The male Macrogamete divides into the Microgamete which fertilize the female Macrogametes
- The female Macrogamets give rise to Zygotes
- As food materials accumulate around the zygote, it becomes in Oocyts
- The oocyts are released at death of mucosa cell
What is the Review of the Coccidian life cycle?
- IN THE HOST
- 1. Sporozoite
- 2. Merozoite
- 3. Gamont
- 4. Macrogamete and Microgamete
- 5. Zygote
- 6. Oocyts
- OUTSIDE HOST
- 7. Oocyst 8. Sporocysts 9. Sporozoite
__ simplest of the Genuses found in farm animals and in birds. Direct life cycle
__ found in the dog, cat, swine and pocket pets
Life cycle is direct or indirect through sporozoite infected mice that serve as faculative host for __
__ sporozoites of __ utilize the direct and indirect means, with the indirect means being far more complex than with Isospora genus
Lifecycle of Toxoplasma:
- eggs pass from the cat
- oocysts, sporocysts, or sporozoites are picked up by intermediate
- sporozoites (or sporocysts) will migrate into the tissues of the intermediates and become encysted or pass to the placenta in the human and cause abortions
- cat eats the intermediate and picks up the sporozoite from the intermediate, thus completing the life cycle
__ felidae (family) is the definitive host, all other domestic and non-domestics serve as intermediates
__ is an ubiquitous protozoan parasite infects virtually all warm-blooded vertebrates (cats are the definitive host)
It is estimated that up to __% of people possess circulating antiboides to Toxoplasma gondii worldwide, implying either active parasite infection or prior exposure
in immunocompetent people, toxoplasmosis is either an inapparent __ or brief flulike illness
People with a brief flulike illness caused from Toxoplasma gondii often present what other signs:
- enlarged/inflammed lymphnodes
Cats with Toxoplasma present what signs:
- abdominal disorder
