1
Q
subkingdom
A
protozoa
2
Q
order
A
eucoccidiorida
3
Q
hosts
A
all horses
4
Q
oval ____ is very large
A
oocyst- 50-60 micrometers
5
Q
oocyst has thin or thick shell
A
thick- shell can come off
6
Q
three phases of life cycle
A
sporulation
infection/schizogony
gametogony/ oocyst formation
7
Q
sporulation
A
unsporulated oocyst pass in feces sing cell develops in oocyst develops into 4 sporoblasts sporoblast develops into 4 sporocysts- each contain 2 sporozoites oocyst is now sporulated
8
Q
infection/ schizogony
A
host becomes infected by ingesting sporulated oocyst sporocysts are liberated sporozoites penetrate epithelial cells is now known as trophozoite trophozoite forms schizont divides and forms mature schizont schizont ruptures and merozoites invade cells gives rise to male and female gemtocytes
9
Q
schizont consists of ____
A
merozoites
10
Q
gametogony
A
male microgametocytes undergo division
form microgametes
microgametes are freed by rupture of host cell
microgamete penetrates macrogamete
results in zygote- oocyst
liberation of unsporulated oocyst passing in feces
11
Q
when does schizogony terminate?
A
when merozoite gives rise to male and female gametocytes
12
Q
macrogametocytes are ____
A
female- unicellular
13
Q
microgametocytes are ____
A
male
14
Q
PPP
A
15 days
15
Q
site of infection
A
small intestine
