Unit 1: Parasite identification and viral inoculation
- Routine stool examination with concentration methods (saline, iodine, floatation, centrifugation, formal ether, zinc sulphate)
- identification of adult worms from models/slides (tapeworm, tapeworm segments, Ascaris, hookworms, pinworms)
- malarial parasite thin/thick smear preparation
- staining and examination for P. vivax and P. falciparum
- life cycle stage demonstration
- demonstration of fertilized hen egg and inoculation routes

Study guide
In this practical you perform routine stool examination with concentration methods (saline, iodine, floatation, centrifugation, formal-ether, zinc sulphate), identify adult worms and segments from models and slides, prepare, stain and examine malaria thin and thick smears for P. vivax and P. falciparum and demonstrate fertilised hen egg and inoculation routes. Learn to identify malaria stages on a stained smear.
Why Parasitology and Virology (Practical) Matters
Stool and malaria examination are among the most frequently performed tests in diagnostic laboratories.
How to Prepare for Parasitology and Virology (Practical)
- Practise malaria smear preparation and staining.
- Learn to identify common ova from photographs.
- Follow biosafety rules with stool and blood samples.
