The formalin-ether concentration technique (FECT) is a widely used sedimentation technique for the diagnosis of intestinal protozoa in preserved stool samples (2). The most commonly used fixatives for stool preservation are either formalin or sodium acetate-acetic acid-formalin (SAF) (3, 24, 40).
Concentration procedure separate parasites from fecal debris and increase the chances of detecting parasitic organisms when these are in small numbers. They are divided into flotation techniques and sedimentation techniques.
Moreover, Why do parasites settle at the bottom when using the sedimentation method?
Sedimentation techniques use solutions of lower specific gravity than the parasitic organisms, thus concentrating the latter in the sediment. It takes advantage of the high specific gravity of protozoan cysts and helminth eggs compared to water. Parasitic elements are sedimented at the bottom.
Secondly, What are the different specimens used for the detection of parasites?
– A fecal (stool) exam, also called an ova and parasite test (O&P)
– Endoscopy/Colonoscopy.
– Blood tests.
– X-ray, Magnetic Resonance Imaging (MRI) scan, Computerized Axial Tomography scan (CAT)These tests are used to look for some parasitic diseases that may cause lesions in the organs.

What are the factors to consider in choosing the right preservative for stool specimen?
Factors such as preservative cost, inhibitor resistance, toxicity, availability, associated labor, sample shipping requirements and study purpose should also be considered when determining an appropriate method for fecal specimen preservation.
How do you get a parasite infection?
Infection that is spread through the fecal-oral route is acquired when a person somehow ingests something that is contaminated by feces from an infected person or animal, such as a dog or cat. Many parasites invade or live in people’s digestive tract. Thus, parasites or their eggs are often present in people’s feces.
How long does it take for a parasite to show up?
Symptoms usually show about two weeks after infection. With treatment, the symptoms can improve in six weeks.
How long does it take for Giardia symptoms to appear?
Occasionally, some people will have chronic diarrhea over several weeks or months, with significant weight loss. The symptoms may appear from 3 to 25 days after exposure but usually within 10 days.
What are the symptoms of having a parasite?
– skin bumps or rashes.
– weight loss, increased appetite, or both.
– abdominal pain, diarrhea, and vomiting.
– sleeping problems.
– anemia.
– aches and pains.
– allergies.
– weakness and general feeling unwell.
How do you treat a parasite infection?
Treatment. For some parasitic infections, no treatment is needed. The infection may disappear on its own. Some drugs (antiparasitic drugs) are designed particularly to eliminate parasites or, in the case of some worm infections, reduce the number of worms enough so that symptoms clear up.
Is zinc sulfate flotation concentration recommended for concentrating trematode eggs?
latum eggs. The sedimentation concentration method should be used; because the eggs are operculated, they will not float using the zinc sulfate flotation concentration method.
What is a parasite infection?
Parasites are organisms that live in (or on) another organism, called the host. The parasites can be microscopic or large enough to see with the naked eye, and they survive by feeding from the host. They can also spread parasitic infections, which can lead to sepsis.
What is the principle of flotation technique?
The principle of fecal flotation is based on the ability of a solution to allow less dense material (including parasite elements) to rise to the top. However, there are numerous factors that will influence the accuracy and use of such a theoretically simple technique.
