Pathogen: biological agent that causes disease to host. Disease: injurious physiological activity caused by continuous irritation by primary causal factor & expressed in characteristic pathological conditions (symptoms) Infectious: disease caused by pathogen which can spread from diseased to healthy host. Non-infectious: disease caused by environmental/host factor; not spread. Ex: heart/cardiovascular disease, cancer, sickle cell, diabetes. Human diseases -> related animal disease (cattle, pigs, birds, monkeys) An infectious disease that can be transmitted from animals to humans. Ex: swine flu, rabies, ebola, plague, lyme disease. Case study: use of molecular tools to study source of disease. Symptoms: high fever, drowsiness -> swelling of brain, death. Pigs eating fruit that bats (flying fox) had fed from.
