Study Notes
Parasitology Overview
- Parasitology examines the relationships between parasites and their hosts.
- Studies the dynamics of how parasites survive, thrive, and impact their hosts.
Basic Definitions
- Parasite: Organism depending on a host for survival, can be unicellular (e.g., protozoans) or multicellular (e.g., worms).
Examples of Human Parasites
-
Plasmodium spp: Protozoans causing malaria, includes:
- P.falciparum
- P.malariae
- P.vivax
- P.ovale
- Leishmania: Unicellular parasites linked to leishmaniasis.
- Entamoeba and Giardia: Cause gastrointestinal infections, including dysentery and diarrhea.
-
Helminths: Group of intestinal worms, notable species include:
- Schistosoma spp.
- Wuchereria bancrofti
- Necator americanus (hookworm)
- Taenia spp. (tapeworm)
- Ectoparasites: External parasites affecting humans, such as ticks, scabies, and lice.
Medical Parasitology
- Focuses specifically on human-infecting parasites.
- Encompasses disease causation, methods of diagnosis, treatment, and prevention.
- Highlights the interconnectedness of hosts and parasites beyond their harmful impacts.
