Study Notes
Parasitology
Definition
- Study of parasites and their interactions with hosts
- Parasites: organisms that live on or in another organism (host) and benefit at the host's expense
Types of Parasites
- Ectoparasites: live on the host's body surface (e.g., lice, ticks, fleas)
- Endoparasites: live inside the host's body (e.g., tapeworms, roundworms, protozoa)
Important Parasites
- ** Protozoa**:
- Plasmodium (malaria)
- Toxoplasma gondii (toxoplasmosis)
- Giardia lamblia (giardiasis)
-
Helminths:
- Tapeworms (Taenia saginata, Taenia solium)
- Roundworms (Ascaris lumbricoides, hookworms)
- Flukes (Schistosoma spp., liver and lung flukes)
Host-Parasite Interactions
- Immune response: host's defense against parasites
- Parasite evasion mechanisms: strategies to avoid host immune response (e.g., antigenic variation, immune suppression)
Parasitic Diseases
- Malaria: caused by Plasmodium spp., transmitted by mosquitoes
- Toxoplasmosis: caused by Toxoplasma gondii, transmitted through contaminated food and water
- Schistosomiasis: caused by Schistosoma spp., transmitted through skin contact with contaminated water
Diagnosis and Treatment
- Microscopy: used to identify parasites in stool, blood, or tissue samples
- Serological tests: used to detect parasite antibodies in blood or serum
- Antiparasitic drugs: used to treat parasitic infections (e.g., antimalarials, anthelmintics)
