Endoparasites Flashcards
1
Q
- Name this parasite and one distinct physical feature
- how does it move?
- what area does it favor?
- cyst shape? which stage can infect?
- intermediate host?
- Clinical Signs?
- Species Affected?
- Diagnosis?
- Is it zoonotic?
A
- giardia
- two eyes
- it’s a flagellate trophozoite–it moves into the intestinal lining
- small intestine
- elliptical, persist/resist
- environmental stage
- none
- acute or chronic diarrhea, fever, with or without emesis
- multiple species
- direct smear(might detect trophozoites, motile, twisting, pear shaped structure, Can stain with Idoine , but this will kill the motile stage.), FF (fecal flotation), snap test, fecal ELISA or direct FAT
- Can be

Q
- Identify
- shape?
- D. Host?
- Intermediate host?
- Diagnosing?
- Clinical signs?
A
- Toxoplasma Gondii
- Coccidian
- Cats are the D.H.
- All warm blooded animals are I.H.
- DETECTION
- Fecal exam (1-3wks active shedding),
- antibody detection (most times cats that are shedding are seronegative. If there is a high titer, this can defintiley mean that there is immunity present or an active infection ( need to accompany c/s)
- serology in humans
- Anorexia, weight loss, GI upset, neurological, abortion, lymph enlargement
- Zoonotic potential

Q
- Name this parasite
- Give an alternate name
- Types of cysts present
- Diagonosis?
- Clinical Signs?
- Who’s mainly affected?
- Which oocysts are resistant to environmental conditions, sometimes surviving up to a year?
- Why might you see these absent an active infestation?
A
- Coccidia
- Isospora
- Unsporulated and sporulated
- Diagnosis
- oocyst structure
- clinical signs
- history
- signalment
- Clinical Signs
- may be mild
- inflammation
- blood loss (if an increased presence)
- chronic diarrhea
- puppies and kittens
- sporulated oocysts
- d/c can eat feces of other animals with coccidia so you need too have c/s too
