Protists parasites Flashcards
Describe the characteristics of Trichomonas vaginalis
- A sexually-transmitted protist (parasite)
- when pH increases, Trichomonas becomes active and replicates which causes inflammation
When does Trichomonas becomes symptomatic?
When pH increases
What are the four types of protists?
- Trichomonas vaginalis
- Giardia lamblia
- Trypansoma
- Plasmodium species
Trichomonas vaginalis can usually be asymptomatic in…
Men
In women, Trichomonas vaginalis symptoms appear when pH is…
Higher than 4.5
Lactobacillus should keep pH between____ which will inhibit the growth of______.
3.8–4.2
Trichomonas vaginalis
What happens if Lactobacillus pH just disrupted?
Trichomonas vaginalis grows in inflammation results
How many life stages does Trichomonas vaginalis have and what is that stage called?
Only 1 lifestage = vegetative cell
Why isn’t there another stage needed for trichomonas vaginalis?
Because they’re never outside the human so no other stages needed
What are the 4 life stages of Plasmodium?
Sporozoite
Merozoite
Trophozoite
Gametocytes
(Back to sporozoite)
What’s the 1st stage of Plasmodium?
Mosquito bites; draws up blood with infected male & female gametocytes.
What happens when male and female gametocytes fuse together inside the mosquitoes gut?
Once inside the mosquitoes gut, both male and female gametocytes fuse together and results into a sporozoite and multiply into more sporozoites
What’s the resulting stage of when male & female gametocytes fuse inside the mosquitos gut?
Sporozoite
Where do sporozoites travel inside the mosquito? For what?
Sporozoites travel to the mosquito salivary gland’s and is ready to be injected into a new host
When a mosquito drops the sporozoites into a new host, what do the do next?
Sporozoites travel to the liver via blood and Reside in the hepatocytes (liver cells)
