Types and Examples in Medical Lab
Understanding how parasites are grouped helps in laboratory diagnosis and identification.
Main Groups of Parasites 🪱
1️⃣ Protozoa (Unicellular Parasites)
• Single celled microscopic organisms
• Common examples: Amoeba, Giardia, Plasmodium
2️⃣ Helminths (Parasitic Worms)
• Multicellular worms infecting intestine or tissues
• Types include Nematodes, Cestodes, and Trematodes
3️⃣ Ectoparasites
• Live on the surface of the host body
• Examples: Lice, Fleas, Ticks, Mites
Why This Matters in the Lab
• Stool microscopy helps detect intestinal parasites
• Blood smear identifies malaria parasites
• Correct sample collection improves diagnosis accuracy
