Eukaryotic Parasites Flashcards
What are the 2 types of parasites
Extracellular- thrive on tissues without entering cells
Intracellular- penetrate host cell for nutrients to complete life cycle
What are the 2 types of intracellular parasites
Vesicular and cytoplasmic
MICROSPORIDIA are opisthokonta parasites, which infection route do they take
Oral- faecal route
Are MICROSPORIDIA opportunistic?
Yes
Which organelle do microsporidia have instead of mitochondria
Mitosomes
Explain the life cycle of microsporidia
They form spores and penetrate the cell via polar tubes to expel parasite into cell
It then grows and the new spores with polar tubes are released from cell to infect another host
Entamoeba are amoebozoa parasites, how do they infect
Oral- faecal route
They infect the colon and can perforate the mucosal layer to form abscesses eg in kidney
How do entamoeba survive when they infect and perforate mucosal layer
As cysts which can then infect another host
Apicomplexa have a secondary plastid; what did they engulf to have this
Red algae (archaeplastida)
What do the apical organelles in apicomplexa parasites do
Allow attachment and internalisation into host cell
What is the secondary plastid in apicomplexa called
Apicoplast
What are the 3 types of apicomplexa
Plasmodium(malaria)
Toxoplasma
Cryptosporidium
Which 2 types of apicomplexa contain a mitochondria and apicoplast
Plasmodium and toxoplasma
Which 2 hosts do plasmodium infect in life cycle
Mosquito and human
Which 2 hosts does toxoplasma usually infect
Cat and their prey eg mouse
