BUG Lecture Final Flashcards
protozoa is also referred to as
coccidia
protozoa comes from the family:
Eimeriidae
What are the two most common Genus of Protozoa?
Eimeria and Isospora
T/F. Protozoa is obligate extracellular parasite.
false. obligate intracellular parasite
what are the three main types of feeding habits of Protozoan organisms? describe them
Saprozoic: nutrients obtained by diffusion through the cell membrane
Holozoic: nutrients obtained through a primitive mouth part
Holophytic: nutrients obtained through manufacture of carbs through photosynthesis
Sporozoites penetrate the epithelial cells of the gut and damage the lining. The most common clinical signs are:
Diarrhea and water loss/dehydration
Most protozoa are zoonotic
False. most are species specific.
Isospora is the most common type of coccidia in cats and dogs
true

Ingesting contaminated flesh
Many animals are ________ of the coccidia parasite
asymptomatic carriers

True
Although no drugs are very effective, the best drug of choice for treatment of Protozoa is:
Sulfonamide antibiotics
Steaming, boiling and strong chemicals like _______ will kill oocysts
Ammonia 10%
An infected cat could produce up to 1,000 oocysts in one day (T or F)
False. Could produce up to 100,000 or more in one day.
What is the Tachyzoite stage of Toxoplasma gondii?
Rapid multiplication once the Sporozoite is in the body
What is the Bradyzoite stage of Toxoplasma gondii?
Cyst stage. Doesn’t stop multiplying but it is very slow
