Flashcards in Eimeria Leukarti Deck (19):
1

subkingdom

protozoa

2

order

eucoccidiorida

3

hosts

all horses

4

oval ____ is very large

oocyst- 50-60 micrometers

5

oocyst has thin or thick shell

thick- shell can come off

6

three phases of life cycle

sporulation
infection/schizogony
gametogony/ oocyst formation

7

sporulation

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

infection/ schizogony

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

schizont consists of ____

merozoites

10

gametogony

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

when does schizogony terminate?

when merozoite gives rise to male and female gametocytes

12

macrogametocytes are ____

female- unicellular

13

microgametocytes are ____

male

14

PPP

15 days

15

site of infection

small intestine

16

pathogenesis

inflammation
disruption of villous architecture

17

clinical signs

benign
foals may get diarrhea

18

diagnosis

sugar flotation
sedimentation

19

treatment

antiprotozoal remedies
