PARASITOLOGY MIDTERM (short thread)

Fixatives not good for sedimentation concentration technique

Top layer of centrifuged tube is composed of

Addition of drops of flotation solution is done until

a. Bulk of fecal debris has formed in the middle layer
b. Eggs and oocysts can be visualized
c. Bubbles rise from the bottom
d. Formation of meniscus

This is placed under the Baermann apparatus to enhance larval migration

This method quantifies the number of parasitic elements per gram of feces.

a. Baermann technique
b. Zinc sulfate flotation technique
c. McMaster technique
d. Formalin ethyl acetate sedimentation technique

Pikachu reported 5400 Taenia eggs per gram of feces. How many eggs were counted on the slide?

Protozoan cysts and trophozoites may be detected after processing the specimen in a concentration technique.

Sedimentation technique is more recommended than flotation technique.
