Study Notes
Parasitism and Medical Importance
- Parasitism is beneficial to one partner and harmful to the other, with the former being called a parasite and the latter a host.
- Medical parasitology focuses on the study and medical implications of parasites that infect humans.
- Many parasites are causative agents of major public health problems, with estimates of prevalence and deaths per year for various diseases.
- Types of parasites include ectoparasites (living on the external surface) and endoparasites (living within another living organism).
- Obligate parasites are completely dependent on the host during their life cycle, while facultative parasites exhibit both parasitic and non-parasitic modes of living.
- Echinococcus granulosus, an accidental parasite, can survive within a host when accidentally taken and cause slow-growing cysts.
- Types of parasites also include erratic parasites that wander into organs where they are not usually found, and opportunistic parasites that occur in immunocompromised patients.
- Different types of hosts include definitive hosts (where the adult or sexually mature stage lives) and intermediate hosts (where the parasite lives during a period of its development only).
- Reservoir hosts harbor the parasite for a long time and act as a source of infection in the environment, while accidental hosts are not normally infected with the parasite.
- Terminology includes monoxen parasites (having only one host for all its life cycle) and heteroxen parasites (having more than one host for their life cycle).
- Pathogens are parasites able to produce disease, and vectors are living carriers that transport a pathogenic organism from an infected to a non-infected host.
- The routes of transmission include congenital, contact, water, soil, and arthropod transmission, as well as avenues of invasion such as the digestive tract, skin, and blood.
