Chapter 5 Flashcards
What do we study within Apicomplexa
Gregarina and Hepatozoon
What kind of parasites are in Apicomplexa
protozoan obligate parasites
What are the structural characteristics of Apicomplexa
single nucleus, no flagella or cilia expect microgametes, apical complex, micropores
What is the apical complex, what is it for, what does each part do
polar rings (tip) , conoid (fibers in ring) , rhoptries (enzyme release to dissolve membrane) , micronemes (also enzyme release) , for cell entry
What are micropores for and what stages are they found in
only in merozoites, to bring in food, vacuole is created to eat it.
What are the 3 stages of life in Apicomplexa?
sporozoite, merozoite, gamont

Explain how sporogony works
sporulation outside of host (exogenous). oocyst divides into sporozoites, 8 sporozoites per cyst
Explain how Merogony/ Schizogony works
sporozoites become merozoites that feed and create meronts (clump), meronts nuclei do multiple fission and create up to 900 new cells. Several generations later they become gamonts
Explain how gametogony works
gamonts can be either micro or macro gametocytes, micros look for macros in cells, fertilization occurs resulting in a zygote,
What animals do Monocytis lumbrici infect
Male earthworms, in their seminal vesicles, NOT HUMANS
How do monocystis lumbrici spread
they shed from the genital pore of the earthworm and are left in the soil, which worms eat up again
How does monocystis lumbrici travel through the body of its host
sporocysts enter through gizzard migrate to seminal vesicle and enter sperm cells
What kind of animals are earthworms? Monacious or Diacious
monacious- M and F
Where in the body do monocystis lumbrici mature
in the seminal vesicle lumen
