Micro 77: Arthropods
This episode concludes parasitology with arthropods, organisms that either directly parasitise humans or serve as vectors for other pathogens. Drawing from Murray’s Chapter 77, it examines their dual role in disease ecology.
Arthropods include:
* Ectoparasites - lice, fleas, mites, ticks
* Vectors - mosquitoes, sandflies, tsetse flies
Direct infestation may cause:
* Pruritus and dermatitis
* Secondary bacterial infection
* Hypersensitivity reactions
As vectors, arthropods transmit:
* Protozoa (e.g., malaria, leishmaniasis)
* Bacteria (e.g., rickettsiae, Borrelia)
* Viruses (e.g., arboviruses)…
