Study Notes
Parasitic Infections
Entrobius Vermicularis (Pinworm)
- Detection methods include:
- Scotch tape test (stick a clear adhesive tape to the perianal skin to collect eggs)
- Cellophane tape test (similar to Scotch tape test)
- Stool examinations (Microscopy and Concentration techniques)
- Perianal swabs
- Graham's method (collecting eggs from the perianal skin using a special tool)
Giardiasis
- Detection methods for Giardia lamblia:
- Stool examinations (Microscopy and Concentration techniques)
- Duodenal aspirate or string test
- ELISA (Enzyme-Linked Immunosorbent Assay)
- Immunofluorescence
- PCR (Polymerase Chain Reaction)
Trichomoniasis
- Detection methods for Trichomonas vaginalis:
- Wet mount or direct microscopy of vaginal discharge
- Culture
- Rapid antigen detection tests
- Nucleic acid amplification tests (NAATs)
- PCR (Polymerase Chain Reaction)
Trichuriasis
- Detection method for Trichuris trichiura:
- Stool examinations (Microscopy and Concentration techniques)
- Kato-Katz technique (to quantify eggs per gram of stool)
Test your knowledge of parasitology by identifying different specimens and the methods used to detect them.
