Study Notes
Protists and Human Disease
- Parasitic protozoa are responsible for most protist diseases in humans.
- Protozoa act as human parasites, leading to various illnesses, some of which may be fatal without treatment.
Trypanosoma Protozoa
- Genus Trypanosoma includes flagellate protozoa responsible for sleeping sickness in Africa and Chagas disease in South America.
- Transmission occurs through insect vectors, particularly the "kissing bug" for Chagas disease.
- The bite of the vector allows Trypanosoma parasites to enter the bloodstream, spreading throughout the body.
- Carlos Chagas, a Brazilian physician, discovered and documented Chagas disease in the early 1900s, identifying its pathogen, vector, host, symptoms, and transmission method.
Giardia Protozoa
- Giardia are flagellate protozoa that cause giardiasis.
- Infection occurs through consuming contaminated food or water, often tainted by feces of infected individuals or animals.
- Giardia attach to the small intestine's lining, hindering nutrient absorption and potentially causing diarrhea, abdominal pain, and fever.
Plasmodium Protozoa
- Plasmodium protozoa are the causative agents of malaria, a prevalent disease in tropical and subtropical regions.
- Transmission is facilitated by mosquito bites, whereby parasites enter the bloodstream and infect red blood cells.
- Symptoms of malaria include fever, joint pain, anemia, and fatigue; it is a serious disease responsible for millions of deaths annually, predominantly among children.
- Ongoing research is exploring the development of a vaccine against malaria.
Summary
- The primary protist diseases in humans stem from protozoa that act as parasites.
- Key diseases include Chagas disease and sleeping sickness (Trypanosoma), giardiasis (Giardia), and malaria (Plasmodium).
