Document Summary

Nearly all organisms are parasitized at some point. Available routes of transmission (e. g. : water-borne transmission) Don"t need to know lifecycles or taxonomy; don"t really need to know about the drugs discussed. Short term (e. g. : mosquito) or permanent (e. g. Short term (e. g. : mosquito) or permanent (e. g. : tapeworm in the gut) Extremely common way of life (50% of animals are parasitic at some stage in life) True parasites include protozoans (single-celled eukaryotes), helminths (e. g. : tapeworms, roundworms, other worms), and arthropods (ectoparasites; parasitic on the outside of the body; i. e. : tics and mites) Success of parasites is defined in terms of: Many are issues related to developing countries; determine likely hood and severity of infection. All of the enteric parasites are transmitted through person to person or water borne. Zoonotic deals with transmission from animals to humans. Toxoplasma has many routes of transmission and this lends to its success.
