Experiment Objectives:

Understand the technique of parasitological analysis.
Develop procedures relating to the Faust method.
Interpret and express the results obtained.
Analyze and compare methods used in clinical fecal parasitology.
Practical Applications:
The Faust method is essential for detecting cysts, protozoan oocysts, and light helminth eggs and larvae. Essential in the routine of parasitological analysis laboratories, this simple, fast and low-cost method is vital for public health.

Experiment Step by Step:

Use the centrifugal-flotation technique in zinc sulfate to enrich fecal samples.
Centrifuge the diluted sample and separate cysts and eggs by flocculation.
"Fish out" the flocculated material and deposit it on a slide for microscopic analysis.
Safety first:

Wear gloves, a lab coat, a mask and safety glasses.
Wash your hands before picking up PPE.
Dispose of used materials in biological waste or in a beaker with sodium hypochlorite.
Experiment Scenario:

Work in a clinical parasitology laboratory with an optical microscope and other organized equipment.
Follow the instructions in the practice script to ensure correct execution of the experiment.
