Protozoa

Question Answer Article
What are the four different ways protozoa can move?
  • Cilia
  • Flagellum
  • Pseduopodia
  • Gliding
 Link to Answer Article
How do protozoa reproduce?
  • By binary fission
  • By schizogony
  • By sporogony
  • By gametogeny
 Link to Answer Article
Briefly summarise the life cycle of protozoa
  • The infectious sporozoite are released from the oocyst invading epithelial tissue
  • The nucleus of the sporozoites divides forming a schizont which contains merozoites (schizogony)
  • Schizont ruptures releasing merozoites which form micro and macrogamonts in the epithelial tissue (gametogeny)
  • Microgamonts penetrate the macrogamont forming the zygote
  • The zygote forms the oocyst which is passed in the faeces
  • Sporulation occurs which makes the oocyst infectious

Coccidia

Cryptosporidia

Giardia

Question Answer Article
What is the key points of the life cycle and prepatent period of Giardia?
  • Simple life cycle
  • Direct life cycle
  • Reproduce by binary fission
  • 5-6 day prepatent period
 Link to Answer Article
How do both people and animals become infected by Giardia?
  • Water bourne transmission
  • Direct faecal-oral transmission
 Link to Answer Article
How would you diagnose a Giardia infection?
  • The cysts are heavy and do not float well in saturated sodium chloride solution
  • Cysts excretion is intermittent so faeces need to be collected and sampled over 3 days
  • Cyst antigen can be detected in faeces by an immunoassay
